LafargeHolcim Group launches ‘Plants for Tomorrow’

LafargeHolcim Group launches Plants for Tomorrow

The global LafargeHolcim Group is on a mission to upgrade all of its cement manufacturing facilities around the world. This drive, called ‘Plants for Tomorrow’, will see over 270 integrated cement plants and grinding mills being upgraded with the latest artificial intelligence and automation technology.

Cement manufacturing facilities, like LafargeHolcim Tanzania’s Tembo cement plant in Mbeya, will get an overhaul of the entire production line. ‘Plants for Tomorrow’ is a four-year initiative that will take LafargeHolcim subsidiaries into the future of cement and building materials.

The upgrades to the cement plants will improve operational efficiency, meaning that these facilities will be able to produce more cement at the end of the initiative. Currently the LafargeHolcim Group is testing the upgrades on 30 pilot projects around the world, where it will iron out any issues before proceeding with a full-scale rollout.

Transforming the cement industry through technology

“Transforming the way we produce cement is one of the focus areas of our digitalisation strategy and the ‘Plants of Tomorrow’ initiative will turn Industry 4.0 into reality at our plants,” says LafargeHolcim global head of cement manufacturing Solomon Baumgartner.

“These innovative solutions make cement production safer, more efficient and environmentally-fit. We are moving to fully data-driven operations in order to support further profitable growth as part of our Strategy 2022 – ‘Building for Growth’,” he explains.

Some of the new technologies to be installed at cement plants

A number of new technologies will be installed at cement manufacturing facilities, such as predictive operations systems that will be able to detect any problems with the production process and implement solutions instantly. This will help to reduce maintenance costs and minimise any downtime of the facilities due to breakdowns. 

The technology will also help to further reduce energy consumption at these facilities. Production lines will become more automated to reduce risks for employees in high-exposure areas of the facilities. 

LafargeHolcim is also planning on using drones to inspect chimney stacks and inaccessible regions of the cement plants. This will allow more frequent inspections to take place while also reducing costs and improving safety standards.

The group is connecting cement plants to a central network

The LafargeHolcim Group is in the process of link all of its global cement manufacturing facilities to a centralised network, dubbed the ‘Technical Information System’. Over 80% of these facilities have already been linked to this system that is able to track performance and allocate resources where necessary.

The Technical Information System also provides specific data at plant, country, region and global levels. This has allowed LafargeHolcim to start building a valuable bank of historical data that can be used to improve efficiency and performance in the future. Since the launch of the Technical Information System in 2006, it has saved LafargeHolcim 184.7-billion TZS in maintenance costs and added around 3-million tonnes of cement through efficient operations.

Concrete for roads and driveways

Concrete can be used to build roads

Concrete is becoming a more popular choice for civil engineers and road builders. Previously, asphalt was the favoured material for building roads but concrete has some unique qualities and benefits that make it a good choice. The three main benefits of using concrete to build roads and driveways are its strength, durability and sustainability.

Another major reason why concrete is becoming a popular road material is its cost-effectiveness over the long-term. Concrete roads will cost a similar price to tar roads, but they will need less maintenance and are less susceptible to potholes over a long period of time. Concrete is a good investment for roads, driveways and parking lots. 

Benefits of concrete for roads and driveways

1. Strength

On average, a road will last between 20 and 25 years before it needs to be completely resurfaced. Roads often need major repairs within the first seven years of their life. Concrete, on the other hand, is a much stronger building material. Concrete roads can last up to 50 years before needing major repairs.

This is due to the strength of concrete. These roads often outlast their initial lifespan. Concrete is designed to last long and withstand lots of wear and tear. This is important for road that need to support heavy vehicles and the friction of rubber tyres.

2. Durability

This brings us to our next point; concrete is durable enough to withstand years of punishment from daily traffic. It is a highly durable material that does not crack or crumble under the weight of vehicles. Concrete can also withstand rain and hot weather, which means fewer potholes.

Concrete has the ability to spread the weight of traffic evenly, which minimises the pressure on the internal structures of the road. Normal roads cannot do this as easily, which is why they are less durable and more susceptible to cracks and potholes. This leads to earlier repair and maintenance needs for normal roads.

3. Sustainability

Concrete is highly sustainable and 100% recyclable. Old concrete structures can be broken down into rubble, which is then reused on new building sites. Concrete is the most widely-recycled construction material. It is also environmentally-friendly, for a number of reasons.

Concrete roads have a light grey colour which is highly reflective. Unlike black road surfaces, concrete roads reflect the sun’s radiation which helps to cool the surface temperature of the road. This is better for vehicle tyres and surrounding buildings – it helps to keep cities and towns cool. Concrete is also manufactured from recyclable natural materials, such as fly ash from coal-fired power stations.

4. Affordability

Concrete is an affordable building material – that is why it is so popular. During its lifetime, a concrete road will cost the government and taxpayer less to maintain and use.

These reasons highlight why concrete is a better building material for roads and pavements. Concrete is relatively inexpensive, but it offers far more advantages over its lifetime. It is strong, durable, sustainable and affordable – ideal for any construction project, including roads.

What is fly ash and why is it used in cement?

Fly ash is used as an ingredient in cement

One of the core ingredients of cement is fly ash. This is a byproduct from the burning of coal in power stations. Fly ash is a fine powder that is light grey in colour and is made up of tiny spherical particles. Fly ash also contains pozzolanic materials, similar to volcanic ash, that react with lime to form cement.

The substance is widely used in the manufacture of cement, including at LafargeHolcim Tanzania’s Tembo cement facility in Mbeya. Fly ash has a number of physical properties that make it perfectly suited to creating cement, which we will outline below:

Physical properties of fly ash

Fly ash is a super fine material. The particle sizes average 45 microns in diameter – that’s 0.045mm. The smallest particles can be just 10 microns thick. This helps to give cement it’s fine, powdery texture which is what makes it a good bonding agent when added to water and aggregates.

These particles are usually spherical in shape and have a glassy texture when viewed under a microscope. The colour of fly ash can differ, depending on whether other chemicals and minerals are present. Lime particles in fly ash gives it a lighter colour, whereas iron gives the ash a brown hue. A dark grey, almost black, colour is usually caused by unburned coal in the power station furnace.

Ordinary Portland cement is made up of about 50% tricalcium silicate – this is the mineral that binds with other materials when hydrated with water. The fly ash in cement combines with the wet tricalcium silicate and begins to fill up empty spaces within the wet concrete mixture. This gives concrete its impermeability and strength once it has hardened and cured.

Other uses of fly ash

This pozzolanic substance has a range of uses in construction, including the following:

  • Used in the manufacture of Portland cement.
  • Used for the construction of embankments.
  • Used as a soil-stabilisation material.
  • Used as a filler mineral in asphalt roads, helping to fill voids in the tar.
  • Used as a component in geopolymers, such as ceramics.
  • Used in roller-compacted concrete dams.
  • Used in the manufacture of fly ash bricks.

How to fix foundation damage on your home

Foundation damage crack in concrete

Foundation damage to any building can occur in a number of ways, from weak soil to water damage. A concrete foundation can be a difficult structure to repair, so it’s best to look after your foundations and maintain them regularly. Keep an eye out for any signs of damage and fix them as soon as possible.

It is possible to repair foundation damage without having to demolish the building, but the process can be time-consuming and sometimes expensive. Foundations are the main support structure of a building. As such, they are an integral part of a building, acting like the skeleton upon which the rest of the structure is built.

Causes of foundation damage

Concrete foundations are strong and durable. However, other problems can occur that affect the strength of these structures. Most of the time, the type of soil and moisture in the ground are the cause of foundation damage. If the soil is saturated with water, it can move beneath the foundations or cause moisture damage to the concrete.

A building can be at risk of foundation damage if:

  • It is built on clay or sandy soil. 
  • If the soil around the foundations has inadequate drainage.
  • The region experiences extreme seasonal changes.
  • There is a major plumbing or water leak underneath the building.
  • Tree roots are growing too close to the foundations.
  • A flood, drought or earthquake affects the soil around the structure.

These problems cause the soil around the foundations to move. This movement is then directly transferred to the foundations themselves, which can cause cracks to form. This can cause the building to weaken and will affect its resale value. The longer foundation damage is left, the worse the resulting problems will become.

Signs of foundation damage

How can you tell if a building has foundation damage, especially if the foundations are below ground? These are the most common signs of stress and damage:

  • Walls leaning, rotating or cracking.
  • Separation of concrete around doors, windows and corners of walls.
  • Extended cracks up the side of the building.
  • Displaced mouldings.
  • Cracking and chipping of concrete where the building meets the ground.
  • Cracks along the floor of the building.
  • Uneven floors and misaligned internal features (like doors that won’t close).

The most common sign of foundation damage is the appearance of cracks on the interior or exterior of the building. Horizontal cracks or jagged cracks along brickwork are the most serious indication of foundation damage and should be addressed immediately.

Methods to repair concrete foundations

The most ideal repair methods are those that don’t require occupants to vacate the building or move their belongings. Luckily, with modern building techniques and technology, there are a few ways in which foundations can be fixed without causing disruption to home life or business.

The two most common solutions are slabjacking and hydraulic jacking. In a slabjacking repair, grout is pumped beneath the foundations to produce a lifting force that restores the foundations to their original elevation. In a hydraulic jacking repair, steel posts are driven into the unstable ground and hydraulic jacks are used to stabilise the concrete foundations.

These methods of repair are used to fix different types of foundation damage. Before deciding on a repair method, you will need to determine what is causing the foundation stress. Get a contractor to look at the cracks and correctly determine the best repair method to use. Slabjacking is suitable for smaller repair jobs whereas hydraulic jacking may be required for bigger problems, where the soil is fundamentally compromised.

Remember to inspect your foundations regularly to catch any issues early on. Regular maintenance will also avoid further problems caused by shifting soil, excess water in the ground and tree roots moving concrete foundations. Always fix any cracks as they appear and contact a professional contractor if you believe that your foundations are compromised.

Tips for mixing and casting concrete slabs

Pouring a concrete slab

Casting a flat concrete slab may seem like an easy task, but there are some important details to remember that will make process safe and successful. One of the first things that contractors will learn on the job is how to pour a flat slab of concrete, whether it is for a floor, countertop or a base for an object.

Here are some things to consider before, during and after pouring concrete slabs. These tips will ensure that you don’t waste money or time during the process. Once you have built the wooden formwork and mixed the batch of concrete, remember the following points:

Safety is paramount

All contractors should wear appropriate safety gear when working with cement and concrete. Workers should have dust masks, goggles, gloves, boots and overalls. Appoint one employee to perform a quality check of the building materials and equipment before mixing the concrete. 

This will ensure that everything is in working order and that a high-quality batch of concrete is created. It will also ensure the safety of other contractors as faulty equipment, such as cement mixers, could lead to injury. This designated worker can also file safety reports and create quality checklists if needed.

Create a detailed batch report system

Before mixing the concrete, print out a detailed batch report that lists all the building materials needed and their quantities for each batch. When measuring out the sand, gravel, cement and water, put a tick beside each material. When adding the materials to the mixer, put another tick next to each item on the list.

This double-tick system will help you keep a detailed record of your building materials and see if there are any discrepancies or losses. It will also help you to accurately calculate how much concrete you will need to mix for the slabs. The batch report can be used for future reference so that you can easily recreate the slab with the correct quantities of materials.

Keep materials, tools and equipment nearby

It will help you to keep all of your building materials (sand, gravel, cement and water) near to the location where you will pour the concrete slabs. Also have all the necessary tools and equipment nearby. This will save time and effort when you need to quickly add some more materials to the concrete batch. It also makes it easier to carry heavy bags of cement or wheelbarrows of sand if they are stored close to the working site.

Pour multiple slabs from the same batch of concrete

If you are pouring several slabs at once, it is important to mix a large batch of concrete and use it to pour all the slabs, rather than mixing a small batch for each individual slab. This will ensure quality and consistency between all the slabs. Any variation in the ratios of wet and dry ingredients will easily be seen in the slabs. By mixing one batch of concrete, you will end up with identical slabs. 

Add materials to the mixer in the correct order

There is actually an ideal order in which building materials should be added to a cement mixer; sand and gravel go in first, followed by water and any admixtures. Next add any fibres and pozzolans. Lastly, the cement should be added gradually to the mixer.

The reason for following this order is simple; if you add cement first, followed by water, it can clump inside the mixer. Mixing the sand and gravel with water first ensures that all of the aggregates are wetted and dispersed. When the cement goes in last, it will combine nicely with the other materials to form a high-quality batch of concrete.

Some other points to remember

If you are hand-packing a stiff batch of concrete into a wooden form, make sure that the concrete goes into every edge and corner of the mould. If you are pouring a fluid mix of concrete, make sure that you release all the trapped air bubbles by tapping on the side of the formwork. 

If you are using steel rebar for reinforcing, make sure that it is suspended in the middle of the concrete batch and that no rebar stick out of the surface of the slab. These are some of the points to remember when pouring concrete slabs. Some of these details can be overlooked, which could affect the quality of the slab, so keep these tips in mind.

What chemicals to use on concrete stains

What chemicals to use on concrete stains

While water is usually enough to remove dirt from concrete, you often need the help of chemicals to clean tough stains. From oil and grease to rust and graffiti, chemical cleaners will make the task of cleaning concrete much easier. 

Many contractors will recommend spraying the stain with the cleaning agent and leaving it to soak for about 15 minutes before using a high-pressure water spray to wash it away. Concrete is slightly alkaline because of the lime in the cement, so we suggest using an alkaline cleaning agent rather than an acidic one.

Oil and grease stains

One of the most common types of concrete stain is caused by oil. Parking lots, roads, pavements and garage floors are all victims of dripping oil from vehicles. Workshop and industrial floors can also suffer from grease stains. The best way to clean these surfaces is to use an alkaline degreaser with hot water.

The degreaser will improve the removal rate of these stains by emulsifying the oil and grease. The hot water will help to lift the oil from the concrete surface. Using a high-pressure water jet will also help to remove the tough stains in the pores of the concrete surface. Alkaline degreasers can also be used to clean soot and soil stains too.

Rust stains on concrete walls

Rust stains can either have a golden-brown appearance or a blue-green colour. They commonly occur on concrete walls around exposed pipes, metal brackets and bolts. Heavy rust stains can sometimes penetrate deep into the wall.

The golden-brown stains occur when steel oxidises and rusts, whereas the blue-green markings happen around copper water pipes. The best cleaning agents to use for these stains are the ones that contain oxalic acid. This chemical helps to break down the metals in the rust stain and make it easy to wash away with a hose or a water jet.

Graffiti on concrete walls

Graffiti on a wall can be very difficult to remove. The type of spray paint used will determine how much effort you need to clean it off. The best way to remove paint stains is to use a chemical stripper that contains a citrus-based solvent, methylene chloride or potassium hydroxide.

The citrus-based solvents are the least aggressive and safest cleaners, which is good for your concrete wall but not as effective at removing graffiti as the other two chemicals. Cleaning agents that contain potassium hydroxide are the best for paint stains. Spray them on the wall and allow it to soak for several hours before spraying the wall with a high-pressure hose. You will also need to spray an acid neutraliser on the wall after the cleaning process to protect the concrete from acid damage.

Another method of cleaning graffiti from a wall is to use a special attachment fitted to a water jet nozzle that feeds sand into the water stream. This essentially sandblasts the paint off the wall. While this method is safe and clean, it can damage the surface of the wall.

These tips will help you remove the most common types of stains from your concrete floors and walls. Water and a cleaning chemical will always give you the best results, but it is important to know what type of cleaning agent to use for each stain.

Concrete safety hazards and how to prevent them

Concrete safety hazards

Working on construction sites comes with a few occupational hazards, including some of the building materials themselves. However, with proper safety training and an awareness of these hazards, they can be easily prevented. All employees need to take the necessary precautions when working on a construction site.

Even the most simple of tasks need concentration, such as pouring concrete. The Occupational Safety and Health Administration (OSHA) has released a set of guidelines to avoid hazards and accidental injury on a construction site. These hazards include the following:

Injuries from lifting heavy objects

Injuries from improper lifting techniques are some of the most common on building sites, especially when it comes to concrete construction. Cement bags are heavy and lifting them in the wrong way can cause a contractor to hurt their spine or neck. 

It is important to train employees in proper lifting techniques and safe load-carrying procedures. When lifting bags of cement and objects over 25kg, contractors should work together to share the load. If employees have to lift heavy objects by themselves, they must lift with their legs and knees, not their back. 

Keep the back straight and bend the knees to pick up an object. Contractors must also avoid twisting when carrying heavy items as this can result in sprained ankles and spinal injuries. With proper training, injuries from lifting heavy objects can be easy to avoid.  

Injuries from falling objects

Construction sites often contain a combination of loose objects, such as tools and bolts, with heights. If a bolt or a drill falls from five floors up, it can cause severe injuries to anybody standing below it. Falling objects can easily be minimised on-site with due care and attention.

If working up on scaffolding, contractors must secure all tools to their belts or to the scaffolding itself. Safety nets can also be erected beneath the scaffolding to catch any falling objects before they hit any workers below. 

Falling off scaffolding

Like the safety hazard above, scaffolding also presents the chances of workers falling from a height. Contractors can slip and fall off scaffolding if they are not paying attention or if they are not secured to the structure. Foremen should always ensure that their employees wear safety harnesses when working on scaffolding.

Concrete structures such as staircases and open windows can also create falling hazards for contractors. It is important to properly train employees to be aware and concentrate when working at heights greater than one metre. Even a small fall can result in leg injuries or concussion.

Chemical burn hazards

Concrete can cause skin irritation and chemical burns if handled improperly. Wet concrete absorbs moisture as it hardens. It will dry skin easily and can damage the skin cells if not washed off properly. If left untreated, concrete on the skin can lead to blisters, swelling or rashes.

These chemical burns and skin irritation can be simply avoided by rinsing concrete off the skin with clean water. Contractors must always wear proper safety gear, including goggles, gloves, boots and overalls when working with wet concrete.

Respiratory irritation or illness

Working with concrete and cement often results in a lot of dust. Cement is a fine powder that can be breathed in and it can irritate the nose and lungs. Breathing in this dust is always a possibility when sweeping, grinding, pouring and cutting concrete.

A simple way to prevent this hazard is to wear dust masks to minimise the inhalation of cement dust on-site. Even contractors who are downwind of the dust should wear masks to prevent respiratory irritation.

Concrete formwork blowout

When working with heavy concrete structures, there is the possibility that the formwork fails and collapses, resulting in a blowout. These breaks can happen when there is too much pressure from wet concrete pressing on weak formwork. These blowouts can injure workers and weaken the actual structure of the building.

All formwork should be erected according to specifications and checked by site managers. They should have appropriate support to hold the weight of the concrete inside. The formwork material should also be capable of supporting the vertical and horizontal loads of wet concrete.

Vehicle or equipment accidents

These are common workplace hazards. Construction sites often have a lot of heavy vehicles and equipment moving around in tight spaces. The drivers and operators of these vehicles and machinery must be properly trained and certified. Not doing so can present risks for the drivers and other contractors working on the site.

Machinery operators must avoid taking shortcuts to save time. Proper operating procedures must be followed at all times, no matter what. Site managers must train their employees to be vigilant and pay attention to their surroundings constantly. Contractors must also wear high-visibility vests so that vehicle drivers can easily see them.

All construction sites should have a person responsible for overseeing the safety and risk management factors. This often falls into the hands of the foreman, but the person responsible must conduct daily inspections and ensure that all contractors are fit to work on the site. While many hazards exist in the construction industry, proper planning, care and safety procedures can easily prevent these hazards from turning into injuries.

How to keep polished concrete shiny

Polished concrete floor

Polished concrete floors can be a beautiful look for any home, office or retail space. The polish adds durability to the concrete surface, protecting it from scratches and scrapes. However, polished concrete surfaces tend to lose their sheen over time, so they do require good maintenance.

Floors in high-traffic areas such as shops and commercial facilities should be polished regularly to keep them looking clean and shiny. However, these types of floors are easier to maintain than other decorative concrete surfaces as they do not require additional waxing or sealing.

Daily cleaning for polished concrete floors

You should try to sweep or mop polished floors once a day to remove any dirt that might scratch the polish. Dust, sand and dirt are abrasive and can remove the polish easily if they are not cleaned daily. Remember to use clean water and a neutral-pH detergent when mopping polished concrete floors.

Try to use a soft mop or cloth to clean the floor so that it does not scrape the dirt across the polished surface. The more traffic across the floor, the more often it should be cleaned. Here are some tips for keeping your concrete floor shiny:

  • Dust mop the floor every day with a microfiber cloth to keep dust and soil off the floor. These particles are abrasive and can ruin the shine of polished concrete.
  • If you are wet-mopping the floor, use clean water and a soft mop. Try to use a neutral-pH cleaner (one that is not acidic or alkaline) to protect the polish.
  • Clean spills from the floor as soon as you can to prevent them from becoming stains. Once a liquid is absorbed into the polish, it can become difficult to remove.
  • Give your detergents enough time to break down tough grime, such as grease or oil. These cleaning agents need to sit on the surface of the concrete floor for a few minutes to loosen the dirt.
  • Do not let the detergents dry on the surface as they can stain the polish themselves. Clean small areas at a time to prevent this from happening.

By following these tips, you will keep your polished floor looking clean and shiny, no matter how many people walk across the surface. A daily cleaning routine will increase the lifespan of your concrete floors and ensure that the polish lasts a long time.

How is sustainable construction shaping the cities of the future?

Sustainable cities of the future

African cities are experiencing rapid urbanisation as more people move into these areas. They are fast becoming densely populated and, with it, comes an increase in energy consumption and waste. So, how can our buildings help to keep our cities sustainable in the future?

If we look at the ideal circular economy, the waste we produce is converted into useful products once again, such as energy or reusable goods. Nature is the perfect example of a circular economy – there is no wastage and everything recycles into the circle of life. Architects, engineers and contractors can learn from nature and make our cities more sustainable.

Our cities are likely to be a lot more green in the future. Trees and plants will be planted wherever possible to control air quality and naturally filter carbon emissions out of the atmosphere. Buildings are likely to have their own source of electricity from solar panels and wind turbines. 

Wastewater and sewage will be filtered and processed to create usable water for washing, watering plants and for use in cooling systems. Our buildings will also harness rainwater for drinking. These are some of the ways in which sustainable construction will shape African cities in the future.

Abundance of trees on rooftops

Research has shown that not only do trees have the obvious benefit of removing greenhouse gases from the air, they can also increase the longevity of building rooftops by protecting them from sun damage and severe weather. The lifespan of a flat roof can be doubled by planting trees on top of buildings. 

These trees will improve the air quality in city centres where excessive carbon emissions from vehicles and industry are pumped into the atmosphere. They can help to combat the effects of climate change and protect the buildings beneath them at the same time. Making buildings last longer also results in less construction waste and a more circular economy.

Recycling water in cities

One of the key features of sustainable construction will be the management of water. Tanzania is prone to droughts and saving water will become a priority for citizens. Buildings in the future will have rainwater catchment systems and filters that allow them to store clean drinking water for residents.

In addition, they are likely to have their own wastewater processing plants. This technology is already being used in Africa, whereby used water from baths, sinks, washing machines and toilets is filtered and treated to create ‘clean’ (but not drinkable) water for use in the household. This greywater can be used to wash, mop and water gardens, which saves the clean drinking water for human consumption.

Harnessing renewable energy

Sustainable construction should carry the benefits forward in the lifespan of a building. This means using renewable sources of energy to generate electricity for residents. Africa is a sunny continent, which means that the use of solar panels to create energy is a viable alternative to coal-fired power stations.

Each building in the city of the future is likely to become self-sufficient. They will have a combination of solar and wind power, backed up by large banks of batteries to store the excess energy created. Harnessing renewable sources of energy will minimise our dependence on coal and water to generate electricity, creating sustainable economies in the process.

These are just some of the ways in which sustainable construction will shape the cities of the future. By tackling several environmental issues at once, skyscrapers and apartment blocks will greatly reduce the impact of human activity on the environment. Most of these sustainable systems will also help cities and citizens to save money and lead more environmentally-friendly lifestyles.
