Rescued hedgehog at LafargeHolcim Tanzania

Hedgehog rescued from ditch at LafargeHolcim Tanzania

LafargeHolcim Tanzania takes pride in protecting the flora and fauna around its operations. All environmental incidents are reported and dealt with swiftly. One such incident in the first week of January 2019 involved a trapped hedgehog.

Christophila Mbiki, a LafargeHolcim employee, spotted the tiny hedgehog in a drainage ditch at the cement factory in Mbeya. She reported the incident and the hedgehog was immediately freed and relocated away from the Tembo cement operations. The hedgehog, who would have perished in the floods, wandered off happily.

Being the rainy season, the drainage ditches around LafargeHolcim are often flooded. It’s small success stories like these that prove that environmental incident reporting and care for the flora and fauna is worth it.

How to make concrete floors

Large warehouse with concrete floors

Concrete floors are durable and easy to maintain. They are a popular choice in modern homes as they keep costs down and are easy to clean. The affordability of concrete floors and the fact that you can make them yourself mean they are suited to Tanzanian homes.

Items needed to make concrete floors

Steps to make your own concrete floors

  1. Using the string and the chalk, mark the desired floor height on the walls around the room. This will be your fill line.
  2. Pour a layer of crushed stone on the floor, about 2cm lower than the fill line. Using the tamper or a steel plate, stamp the stones down to compact them. Make sure they are level.
  3. Pour a layer of sand over the crushed stones and pat it flat with a trowel or shovel. The sand should be about 1cm below the fill line.
  4. Lay a plastic sheet on top of the sand and tape the edges to the side of the wall along the fill line.
  5. Mix your Tembo cement with water in a wheelbarrow. FastaPlus works best as it is durable and can support weight. Follow the instructions on the bag.
  6. Starting at the wall furthest from the door, place a layer of concrete on the plastic sheet with a shovel.
  7. Use a straight plank to scrape and level the concrete along the fill line, covering the plastic sheet and smoothing the concrete along the base of the walls.
  8. Use a trowel and extra concrete to fill in any gaps or indentations. Use a plastering trowel or a float to smooth the concrete floor nicely.
  9. Allow the concrete to cure for seven days, keeping it damp the entire time.

How to lay a concrete driveway

House with concrete driveway

If you’re building your own driveway, it’s important to use high-quality cement. Driveways have to support heavy cars and endure years of wear and tear, so the concrete needs to be strong and durable. A well-laid concrete driveway can last up to 30 years.

The driveway should be at least 7.5cm thick and between 2.5m to 3m  wide. To allow for expansion in the hot Tanzanian weather, joints should be created in the concrete every 2.5m – this means laying square panels of concrete to complete the driveway.

There should be no dips or depressions in the concrete as water will accumulate and affect the durability of the driveway. The concrete driveway should also slope away from any garage or house for at least 1m so that rainwater does not run into the building.

Prepare the area for the concrete driveway

The ground where the driveway will be laid needs to be prepared properly before starting the project. Make sure the soil is solid and stable. Remove all grass, plants, roots and topsoil. Dig a foundation about 10cm deep – it should be the same width and length as the driveway.

Make sure that the soil is compacted down and at the same desired level as the driveway. You can roll a straight gum pole along the soil to compress it and smooth it, like a makeshift roller.

Next, install your wooden formwork. Timber planks (at least 75mm in width) can be held in place by metal pegs along the length of the plank. The concrete driveway will sit flush with the top edge of the formwork, so make sure to treat the wood with a coat of form oil to prevent the concrete sticking to the wood.

The forms should be at least 2.5m by 2.5m. This will allow you to lay square concrete panels in sections, as discussed above.

Materials needed to make the concrete driveway

You’ll need durable cement – Tembo FastaPlus is ideal for concrete driveways – as well as sand and 19mm stone. Remember to store your cement and aggregates in a clean and dry environment, out of direct sunlight and away from contaminants such as soil, seeds and leaves.

A single batch of concrete can be made from one bag of cement, 80 litres of sand, 80 litres of stone and enough water to make the right consistency. A cubic metre of concrete will need about eight bags of cement and 640 litres each of sand and stone.

Wheelbarrows or 25-litre drums are useful ways to measure sand and stone quantities. Just make sure the drums or wheelbarrows are clean from oil, dirt, sugar and other contaminants. A builder’s wheelbarrow is 65 litres when the aggregate is level with the rim.

Laying the concrete driveway

Once your foundation is flat, the forms laid and you have the right materials, you can start the process of laying the driveway. To mix the concrete, first put a layer of sand down on a clean and smooth surface – about 10cm will do. Then, spread the cement on top of the sand and mix the two until the colour becomes uniform.

Next, slowly add water until the consistency is like a thin porridge. Finally, add the stones and mix thoroughly. The concrete should be able to stand in a heap but should settle quickly when tapped with a shovel.

Now you can start laying the concrete. Spray a bit of water on the soil foundation to moisten the base, but don’t leave pools of water. Each square section of the driveway should be laid in one go.

Place a layer of crushed stone or gravel (at least 4cm thick) at the base of the foundation. Pour the concrete over the top and fill the wooden forms. Make sure there are no gaps along the edges or in the corners.

Use a thick plank that is long enough to reach either end of the forms pat down the concrete. When water starts to appear on the surface of the concrete, then it has been compacted enough. Then, using the same plank, slide it along the top of the forms to scrape away any excess concrete. Fill any holes if needed.

If you want to add some grip to the driveway, brush it with a dry broom once it has started to harden. This will create tiny lines in the concrete and give it some texture. You should be able to lay two or three panels of concrete per day.

To form expansion joints between panels, lay alternating sections (i.e. lay the first panel, then leave a gap for the second panel and lay the third panel). You can then lay the gaps the following day, once the forms are removed. This will create separate panels in the core of the driveway to prevent cracking in hot weather.

Protecting and curing the concrete driveway

Once the driveway is laid, it needs to be protected from the weather while it cures – especially in hot, dry and windy conditions. Cover the driveway with plastic sheeting and keep it damp for about 10 days if the weather is warm. Keep the plastic sheet in place with stones or planks to weigh it down and stop it from blowing in the wind.

After 7 to 10 days of damp curing, remove the cover. The driveway will be able to support the weight of cars after another five days, and bigger trucks after another 10 days.

How to lay a foundation

House foundation with wooden formwork

One of the most important parts of any construction is the foundation. A solid and strong foundation will give the structure something to stand on. Every wall, house and building needs good foundations and quality cement to make it last for decades.

Laying the foundation is the first part of any project and it’s a basic skill that needs to be mastered. LafargeHolcim Tanzania offers a range of cement and the durable FastaPlus brand is perfectly suited to building foundations.

Items needed to lay a foundation

  • Tembo FastaPlus cement
  • River sand
  • Water
  • Aggregate
  • Spade or pickaxe
  • Wheelbarrow
  • Trowel
  • Spirit level
  • String
  • Steel pegs

Steps to lay your own foundation

  1. First, you’ll need to prepare the ground. Mark out the shape of the foundation with string and steel pegs and clear any rocks, trees or plants.
  2. Dig a trench or pit for the foundations (about 25cm deep for a house) using a pickaxe or spade. The higher the wall or building, the deeper the foundations need to be.
  3. Level and compact the soil in the trench or pit. Pour in a layer of loose sand or gravel to cover the mud at the base. This will prevent moisture from seeping up through the ground while you lay the concrete foundation. Put a layer of polyethylene plastic sheeting on top of the sand or gravel for added moisture protection.
  4. Construct a wood form to outline the foundation site according to the dimensions of your structure. Now you can mix and pour the concrete.
  5. Mix two bags of FastaPlus cement with 50 litres of water, three wheelbarrows of sand and three wheelbarrows of aggregate. Adjust these ratios until the consistency of the concrete is just right. Start pouring the concrete into the foundation and level it across the top of the wooden form to ensure it’s flat.
  6. Once the excess concrete has been removed and the foundation is leveled, remove the wood form. You can use a trowel to add bits of cement to dips in the surface of the foundation. It is best to do this while the concrete is still damp and mouldable.
  7. When the foundation is perfectly flat, leave it to cure for up to 28 days. Keep the concrete covered and damp while it’s curing.

How to build a wall

Builder building a wall

One of the first skills a builder learns is how to make a simple wall. No matter the purpose of the wall, whether it’s to build a house or surround a garden, the basics stay the same. Choose some bricks and use the right brand of cement – Tembo is perfect for general purpose projects such as walls.

Items needed to build a wall

  • Tembo and FastaPlus cement
  • River sand
  • Water
  • Bricks
  • 13mm or 19mm stones
  • Shovel
  • Wheelbarrow
  • Pickaxe
  • Trowel
  • Spirit level
  • Builder’s square
  • String
  • Steel pegs

Steps to build your own wall

  1. First, you’ll need to make the foundation. Mark out where the wall will be built with some string and steel pegs. Remove any grass and tree roots, then dig a trench 25cm deep (for a wall 150cm high) using a pickaxe. The higher the wall, the deeper the foundations need to be – about one fifth the height of the wall.
  2. Mix your Tembo cement with the river sand, water and small stones. Mix two bags of cement with two-and-a-half wheelbarrows of river sand and two-and-a-half wheelbarrows of small stones. Add 50 litres of water and mix thoroughly.
  3. Spray a small amount of water into the trench to make it damp, but make sure there are no puddles. Fill the trench with concrete and allow to cure for seven days. Keep the concrete covered and damp while it’s curing.
  4. Now it’s time to build the wall. Mix a mortar using one bag of FastaPlus to four wheelbarrows of plaster sand and 25 litres of water.
  5. Mark a straight line on the foundation using the string and steel pegs, then place a layer of mortar (about one centimetre thick) along this line using a trowel. Start laying your bricks on top of the mortar and make sure they are level using the spirit level. Keep the bricks aligned with the string to ensure that your wall is straight.
  6. Pour some mortar between the bricks and scrape off any excess with the trowel. There should be about a 1cm gap between bricks. Continue placing bricks and filling the gaps with mortar along the length of the wall until the first layer is done. Don’t forget to use the spirit level to check that each brick is perfectly level.
  7. Add a layer of mortar on top of the first layer of bricks. For every second layer of bricks, move them half a length over. Do this by laying half a brick at one end and then continuing normally to the end of the wall. This staggered pattern is what gives walls their strength.
  8. Continue building the wall with a staggered pattern and checking the alignment of the bricks with string and a spirit level.
  9. For extra strength and reinforcement, you can lay some brick force steel wire along the length of the wall at every fifth level of bricks. If the wall is long, leave an expansion joint every four metres and fill the gap with styrofoam or some other compressive material.

The importance of aggregates in concrete

Three different aggregates

Concrete consists of three core ingredients; cement, aggregates and water. Aggregates play a major role in holding the concrete together and adding to the durability of the finished product. Using the right aggregates is important when it comes to the performance of the concrete – they make up between 60% and 80% of concrete, after all.

The main types of aggregate are sand and gravel. These both come in a variety of forms, such as fine river sand, small gravel chips or larger crushed stones. A combination of aggregates can be used to create the perfect concrete texture for your project.

Choosing the right aggregates

The size, weight and moisture content of aggregates will directly affect the quality of the final concrete mix. Aggregate choice can also affect the cost, workability and durability of the concrete, so it is a major factor to consider when starting a construction project.

Aggregates should be clean, hard and strong. Choose aggregates that are free of clay coating, soil impurities, additional chemicals and organic material. Sand and gravel should not contain any mud, seeds or leaves.

Other factors to consider when choosing aggregates

The moisture content of aggregates is also important. It can affect the water-cement ratio in the concrete mix and either cause the concrete to be too dry (by absorbing the water) or too wet (by adding additional moisture to the mix).

Ideally, the aggregates should be in a saturated surface dry (SSD) condition. This means that they are dry on the outside but have internal moisture. In turn, the aggregates will not absorb any moisture from the concrete mix and leave it too dry.

Choosing the right gradation is also important. Aggregates that are too fine will need more water and will result in a sticky concrete mix – such as ultra-fine river sand. Aggregates that are too coarse will make the concrete harsh, hard to work and more difficult to place. The key is to find the right balance with aggregate gradations.

Aggregates make up the majority of concrete and are a vital factor to consider. Depending on the project and the final finish of the concrete, choose the right aggregate for your needs.

How to make concrete bricks and blocks

Pile of concrete bricks and blocks

Making your own concrete bricks and blocks is easy. It can be done outside with just a few items and will save you money. Small-scale businesses can even be started through the production of concrete bricks.

Concrete bricks and blocks can be solid or hollow, it depends on the builder’s preference. Hollow bricks and blocks are lighter and require less concrete to make. Bricks are smaller than blocks, but both can be made using the same techniques.

Making concrete bricks is quite easy, but they need to have a standard size and consistent quality if they are to be sold for a profit. Whether you want to make concrete bricks to sell or for your own building project, here are a few things to think about.

Choosing a site for making concrete bricks

Before you start constructing your own concrete bricks, make sure you have access to a flat piece of land big enough to store the equipment, materials and finished bricks. There should be enough space to store the aggregates (rocks or gravel and sand) and cement.

Do not store the aggregates or cement on bare ground as soil and water can contaminate the materials. Do not store them under trees as leaves and seeds can fall into the stockpiles. Keep aggregates and cement dry and separate until you need to mix them. Bags of cement should ideally be stored in a dry room.

You’ll need space to produce and store the concrete bricks and blocks. A flat concrete slab is ideal – about 50 square metres is big enough to store 1000 bricks or 200 blocks for curing and drying. This slab can be slightly sloped to ensure that rainwater runs off but not so much that the stockpiles fall over.

Using the right equipment to make concrete bricks

To make your own concrete bricks, you’ll need various general purpose tools and a moulding machine. There are two types of moulding machine – a stationary block moulder that produces one brick at a time on a pallet, and an “egg-layer” machine that moulds bricks on a concrete slab. Both of these moulding machines come in hand-operated versions and electrically-powered versions.

Concrete mixers are not necessary, but they do make the process easier. Mixing concrete by hand will save money but it is more physically challenging. It can be done with a shovel on a flat concrete slab or steel sheet. Never mix concrete directly on the earth as the soil will contaminate the mix.

If you are able to use a concrete mixer, only a pan mixer should be used. Drum mixers do not work because they cannot mix the semi-dry concrete needed to make bricks. Other equipment needed includes wheelbarrows, hosepipes, plastic sheeting and shovels.

Using the right cement and aggregates

The cement used for making concrete bricks should be strength class 42,5N or higher as the concrete needs to cure as quickly as possible. Tembo Cement’s SupaSet and TemboFundi brands are ideal for this purpose.

Sand and stones will form the aggregates for the concrete bricks. You can use fine river or pit sand, coarse sand (up to 5mm in size) or stones with a maximum size on 13mm for solid bricks or 10mm for hollow bricks. Usually, it is possible to make concrete bricks with just coarse sand, but a combination of aggregates can be used.

When making your first batch of bricks, try using coarse sand only. Then replace some with fine river sand and stones to see what makes the strongest mix for your bricks. Try using aggregate to cement ratios of 6:1, 8:1 and 10:1 (230 litres, 300 litres and 380 litres of aggregate per 50kg bag of cement).

For each combination or ratio, mix a batch of concrete with water and use the brick moulding machine to create some test bricks. This will allow you to find the perfect mixture for your needs – the heavier the freshly moulded brick, the better. Test the strength of the dried bricks by knocking them together – a hollow thud means they may be weak, a ringing sound means that they are strong.

Making your own concrete bricks

Once you’ve established the best mixture for the concrete bricks and blocks, you can start producing them in larger quantities. Make sure you have enough cement and aggregates to make the number of bricks you require.

Using an aggregate to cement ratio of 8:1 with three-and-a-half bags of cement and a cubic metre of aggregates will produce enough concrete mixture to make about 400 bricks. This number can vary depending on the size of the bricks and whether they are hollow or solid.

The amount of water added to the concrete mix is usually judged by eye. Once the approximate amount of water needed per batch is known, measure about 90% of this and add it to future batches. The remaining 10% can be added slowly to get the right consistency of concrete.

The concrete mixture must be wet enough to hold together when compacted, but not so wet that the bricks sag and deform when removed from the mould. If you see ripple marks on the bricks once they are moulded, then your mixture has slightly too much water. If the concrete is too dry, the bricks won’t bind properly and will crumble when dried.

To mix the concrete, first spread the sand out on a steel plate or concrete slab. The sand should be 5cm to 10cm thick. Spread the cement over the sand and add any other aggregates. Mix the sand and cement with a shovel until a uniform colour is achieved. Sprinkle water over the surface of the mixture and continue to mix until the right consistency of concrete is achieved.

Place the concrete in the moulding machine and compact it about six to eight times to ensure that the brick is properly formed. Take the moulded brick out of the machine with care and set them somewhere to cure for seven days. The bricks should be protected from rain and direct sunlight while curing.

You can cover the bricks with a plastic sheet to prevent moisture loss. A light spray of water may be necessary if it’s hot and windy. This will allow the bricks to cure properly and avoid drying too quickly. Congratulations, you’ve just made your own concrete bricks or blocks.

Aggregates: the difference between crushed stone and gravel

Crushed stone and gravel aggregates

Aggregates are an essential part of any concrete mix. Different concrete projects call for different aggregates, so make sure you know what the differences are between the aggregates. Crushed stone and gravel are not the same, even though they come from the same ore and the same quarries.

Crushed stone and gravel have different uses in construction. This is why aggregate suppliers will sell them separately. They have different methods of production and separate applications. Here are some details that you should know.

Production of crushed stone and gravel

Crushed stone is the result of breaking down large rocks in a crushing machine. The most common ore used to make crushed stone includes granite, limestone, trap rock, basalt, dolomite and sandstone.

Gravel is a natural product of weathering and erosion. It can be collected from river beds or harvested from the same quarries that produce crushed stone. The types of ore in the gravel are similar to crushed stone.

Crushed stone usually has more angled surfaces than gravel as a result of the crushing process. Crushed stone can also range in size from fine dust to large rocks. Gravel is more rounded and often smaller than crushed stone. Gravel also comes in various sizes, from 6mm up to 50mm.

Uses for crushed stone and gravel

Both aggregates are most commonly used for construction projects. The angular surfaces of crushed stone make it perfect for forming flat surfaces when compacted or rolled. It makes a stable, interlocking base for concrete foundations, roads and floors.

Crushed stone is also ideal for railway track ballast beds, a filler element, drainage system and retaining walls on shorelines and mountain roads.

Gravel, being smoother, is often used for aesthetic purposes. It also has a wider range of natural colours, which makes it ideal for decorative landscaping on pathways and flower beds. Gravel is also used as a flooring material on patios, paths, stepping stones and driveways.

If you want an aggregate for construction purposes, crushed stone is your best option. If you need an aggregate for decorative purposes, then gravel is the answer. The two aggregates have different purposes so use the right stone for the job.
