Three untrue myths about concrete

Three untrue myths about concrete

There are many myths and beliefs about concrete in the construction industry. Some contractors may believe these myths and, as a result, shy away from using concrete in a project, in favour of other less adequate building materials. Concrete is a strong, resilient and cost-effective building material, so take note of the following three myths.

1. Adding lots of water to the concrete mix will be better

Many contractors believe that the more water you add to the concrete mix, the better the results will be. In truth, the correct water to cement ratio is absolutely vital to the final quality and strength of the concrete. By adding too much water, you actually weaken the bonds between the materials in the concrete mix. This can lead to brittle concrete that is prone to cracking. It also makes the concrete slump and runny, which means that it can leak out of formwork easily.

2. All concrete will crack

This is simply untrue! If the concrete is mixed, poured and cured correctly, it should never crack. Any cracks in concrete are the result of improper building practices or shortcuts being taken. If a contractor does not use the right ratios of cement to water to aggregates, then the final concrete structure can be compromised. Not allowing the poured concrete to cure properly afterward can also result in a weaker structure. Concrete will not crack if due care is taken throughout the entire process.

3. Concrete does not require maintenance

Many homeowners believe that concrete requires no maintenance. While concrete is incredibly durable, it does need to be looked after. Concrete structures and surfaces should be cleaned regularly, inspected once in a while and repaired as soon as any defects present themselves. Homeowners need to look after their concrete surfaces as they are an asset and can impact the value of the home.

These are the three most common myths about concrete that can mislead contractors and homeowners. Concrete is a versatile and useful building material, especially when it is used properly and looked after in the decades following.

Things to know about mortar for bricklaying

Things to know about mortar for bricklaying

The two most common types of mortar used for bricklaying are cement and lime mortar. They have different properties and strength characteristics, so it is important for contractors to which one to use for a project. LafargeHolcim Tanzania manufactures a few cement products that are suitable for use as mortar in brickwork. These are Tembo cement, TemboFundi and FastPlus.

Here are the things that contractors should know about mortar for bricklaying and brickwork construction:

1. Mortar does not affect the strength of brickwork – Various mortar mixes have different strengths, but they do not affect the overall strength of the brickwork. For example, mortars of mix ratios 1:6 and 1:4 have different strengths, but the brickwork will have the same strength in both cases, regardless. This is because the strength of brickwork depends on the bricks used, not the mortar.

2. An ideal mix ratio is 1:3 – When a mortar is mixed with one part cement (or lime) to three parts sand, it creates a dense mortar with fewer voids. This is an ideal mix ratio for most projects and general applications. A mix ratio richer than 1:3 is not used in bricklaying because of the high shrinkage rate. 

3. Lime mortar has a few advantages – Although lime mortar is generally weaker than cement mortar, it does have a few other advantages:

  • Lime mortar does not experience as much shrinkage as cement mortar.
  • Lime increases the workability and plasticity of the mortar mix.
  • Lime has good water retention and the mix does not dry out as quickly.
  • Lime can increase the volume of mortar by filling voids.
  • Lime makes the mortar more water-resistant and impervious to rain.

4. Lime mortar gains strength slowly – This is the reason why lime has a lower strength than cement. Lime mortar may develop early strength but it does not develop long-term strength as quickly as cement.

5. Cement-lime mortar ratios are important – When mixing cement and lime to form a hybrid mortar, it is important to know that leaner mixes (a ratio between 1:4 and 1:8) tend to be harsh when mixed with coarse sand. In these cases, plasticisers are recommended to help improve the workability of the mortar.

6. Sand affects the strength of mortar – The following factors of sand affect the strength of cement mortar, regardless of the ratio between cement and sand:

  • The grading of the sand.
  • The fineness or coarseness of the sand.
  • The angularity and roundness of the sand particles.
  • The fineness or coarseness of sand affects the plasticity of the mortar mix. Plasticity can also be increased by adding more cement to the ratio.
  • Fine sand results in a more workable mortar but more cement and water will be needed in the mix. This increases the water-cement ratio which reduces the strength of the mortar.

8. Curing is critical – The curing process is absolutely necessary to achieve the maximum strength of the mortar mix. Curing can take about seven days after bricklaying.

9. Common mistakes in brickwork mortar – The following are common mistakes that are made by contractors when making mortar mixes for bricklaying:

  • Not mixing the mortar properly.
  • Adding too much water to the mixture.
  • Laying a thick bed of mortar between bricks.
  • Using dry bricks that suck moisture out of the mortar.
  • Uneven joints between corners and bricks.
  • Voids in vertical joints between bricks.
  • Disturbance of bricks after laying.

10. Addition of pozzolana – Adding pozzolana to the mortar mix increases its strength and makes it more resistant to chemicals and harsh substances.

Things to consider when pouring concrete during the rainy season

Pouring concrete during rainy season

Construction projects are planned and executed all-year-round. This means that contractors need to build in some extreme weather conditions, from searing hot and dry temperatures to windy and rainy weather. These factors can all affect concrete and how it cures, but the rainy season can be particularly hard because it brings water and wind.

Contractors need to keep an eye on their concrete structures during the rainy season. Rain can affect the surface appearance of concrete as well as the internal strength. When the concrete is between its initial setting time and final setting time, the rain can leave patch marks and pores in the wet concrete. This can disturb the upper layer of the concrete before it can cure properly.

Rain can also affect the internal strength of concrete. If there is consistent and heavy rain for multiple days, the excess water on the concrete can slow down the curing process. This can affect the internal bonds between the concrete particles and make the mixture weaker than intended. Here are some other points to consider when pouring concrete in the rainy season.

1. Extra water in the concrete mixture during the rainy season

If you store your aggregates outside, the rain will make the sand and crushed stone wet. This will add extra water to the concrete mix, so remember to use less water when making a batch of concrete. You will also need to keep an eye on your cement and ensure that no moisture gets into the bags while they are being stored. The cement needs to be stored in a dry environment at all times.

2. Use waterproofing admixtures in your concrete

During the rainy season, consider using hydrophilic crystalline admixtures in your concrete batch. These admixtures react with water and cement to form calcium silicate crystals. The crystals block pores and microcracks in the concrete and prevent water from seeping into the structure. Essentially, they seal the concrete and protect it from excess water damage.

3. Avoid pouring concrete during heavy rains

Make sure that the weather conditions are not too wet or windy before you decide to pour concrete. Keep an eye on the weather forecasts and try to find a gap of at least 12 hours where there is no rain. Fresh concrete needs about 12 hours to start the curing process and any rain could affect this. The wind can also have a negative impact on the curing process. Strong winds can cause bleeding in the concrete and affect the evaporation rate of its internal moisture.

4. Rain can cause delays

It is a well-known fact that rain can affect traffic. This can create delays for the transport and delivery of concrete batches. Suppliers need to keep an eye on the weather and avoid making deliveries during the rain. If this is not possible, then drivers should plan to use alternative routes with less traffic. Any delays in delivery will be costly to the project and will allow excess water to affect the construction site.

5. Use waterproof covers to protect concrete

Plastic sheeting and waterproof canvas should be kept on-site during the rainy season. Once a concrete batch is poured, cover it with the sheeting to shield the concrete from the rain. This will keep moisture in the concrete and keep excess water out. Waterproof covers can also be used to protect aggregates and keep them dry.

6. Perform inspections after the rain

Once the rain has subsided, asses the concrete and see if there is any damage or pools of water on the surface. A simple scratch test can be done to see if the surface of the concrete has been affected by the rain. If there is any surface damage or dimples left by the rain, contractors can use a float to remove excess pools of water and smooth the surface of the concrete at the same time.

The key to ensure the success of a building project during the rainy season is preparation. Be ready for heavy rains and have the right equipment and materials on-hand to deal with the wind and water. Pouring concrete in the rain is not advisable – rather stop and wait for the rain to pass, then remove the surface water in the foundations or on the already-poured concrete before completing the pour.

Inspection checklists for pouring concrete

Inspection checklists for pouring concrete

All construction projects should be inspected at least once a day. This will ensure that the quality of the structure is up to standards and that the work is being done properly. An inspection is especially important when pouring concrete. There are a number of checks that should be performed to record the process and make sure that quality control measures are followed.

The inspection of concrete can be performed in three stages; pre-placement, during placement and post-placement. It will be beneficial to the contractor and the client if these steps are recorded and supervised. This will minimise any discrepancies during billing and the completion of work.

The following inspection checklists can be used to measure the volume of concrete used and to ensure that everything is in order before, during and after pouring concrete.

Avoid these common construction mistakes

Image of common construction mistakes

A building’s quality and resilience are not only affected by the materials used to construct it. Workmanship and building techniques also determine how well a structure will be completed. Poor concrete construction methods will result in a badly-built structure. Construction mistakes are made when contractors are not trained properly or when they are negligent.

Poor construction methods can also be the result of inadequate supervision from project managers or inadequate quality control. The lead supervisor on any construction site must check the workmanship and inspect the quality of the building on a daily basis. Here are the common construction errors that supervisors need to look for.

Common concrete construction mistakes

1. Inadequate concrete curing

The curing process is vital when it comes to the quality and strength of a concrete structure. Concrete needs to be kept hydrated for about 28 days after pouring to ensure that it cures sufficiently. The main cause of poor curing is not keeping the concrete wet during this time. This negatively affects the strength of the concrete and can cause it to shrink, resulting in cracks and a brittle structure.

2. Poor concrete compaction

Even if you use the highest-quality cement and building materials, poor concrete compaction will lead to a bad structure. Concrete compaction is important because it removes air bubbles and creates a solid, dense and well-bonded structure. Propper ramming and vibration is needed to ensure that all the trapped air inside the wet concrete is removed.

3. Concrete segregation 

This construction mistake is the result of poor mixing of cement, water and aggregates. If the aggregates and mortar mix are not properly mixed, the concrete can segregate. Segregation can also occur when concrete is dropped from a height. Contractors need to use chutes or pipes to transport mixed concrete down into a building basement. A concrete mix with a high volume of aggregates, or over-compaction, can also cause aggregates to sink in the concrete mix, leading to segregation.

4. Incorrect placement of steel rebar

The placement of steel rebar within a concrete structure is vital. It forms the inner skeleton of the structure and provides extra strength and reinforcement. Incorrect placement of steel rebar can lead to a weakened structure. If this rebar is exposed, it can also lead to rust and corrosion – especially in coastal regions. In the worst-case scenario, steel rebar that is badly placed can lead to a sudden collapse of the structure.

5. Concrete leakage in bad formwork

Concrete leakage is a common mistake that takes place when concrete is being placed and compacted in formwork. The formwork needs to be airtight and properly sealed. If the joints in the formwork are not tight, the wet concrete will seep through the gaps and the water inside the concrete will leak out. This will result in a hardened concrete with a high cement to water ratio. The concrete will be weaker, more brittle and prone to cracking and chipping.

6. Incorrect construction joints

This point leads on from the last – construction joints need to be created with proper preparation and execution in line with the original architect drawings. Before making joints between new concrete and old concrete, the surface of the old structure needs to be washed and prepared properly. This will ensure a proper bond between the two structures. If the construction joints are not good, a number of issues can arise, including moisture penetration, concrete staining, cracking, disconnection and compromised structural integrity.

7. Concrete with high water content

Experience is important when it comes to concrete mixing. Sometimes, inexperienced contractors do not use the right amount of cement, water and aggregates in a concrete mix. The most common of these mistakes is using too much water. A high water content will make the concrete slump and decrease its workability. Too much water will also affect the final strength of the mix.

These are common mistakes that can be made on construction sites by inexperienced builders or through poor supervision. Project managers need to inspect the building process and completed jobs on a daily basis to ensure that these mistakes are not being made. These mistakes can determine the final quality of a building so they need to be avoided.

Update your business space with concrete

Update your business space with concrete

Concrete is a wonderful building material. Not only is it perfect for the structure of buildings, but it can also be used in a decorative way. Business owners, restauranteurs and retailers should consider incorporating concrete into the interior design of their workspaces. This will modernise and improve the look and feel of the office, restaurant or store.

Concrete can be used to create clean designs and improve the value of a business space. By investing in concrete design upgrades, business owners will be able to sell the property for more when the time is right. Concrete can give an office a sleek and contemporary look, so consider using it to update your business space.

Types of businesses that can benefit from concrete

Almost any business can use concrete to its advantage. From concrete countertops and floors to exposed beams and patios, concrete is an excellent interior and exterior addition to a commercial property. The following businesses can benefit from concrete upgrades:

  • Restaurants
  • Bars
  • Clothing stores
  • Grocery stores

Any business space can use concrete to create a polished floor that is modern and easy to clean. Concrete is affordable and durable – perfect for businesses that have a lot of foot traffic across the floor.

Concrete doesn’t have to be a grey slab either. It can be made to look like other materials, such as granite, wood and stone. Contractors can colour concrete using dyes and shape it using overlays to make the surface bright, textured and aesthetically pleasing. Overlays can make the surface of the concrete resemble wood, stone slates and tiles.

Why choose concrete for a business space?

There are many reasons why a business should consider using concrete in its interior design. Firstly, concrete is incredibly durable. It can withstand the wear and tear of customers and employees without cracking, chipping or scratching. Concrete requires very little maintenance and it is simple to clean.

Building relationships between contractors and architects

Building relationships between contractors and architects

A successful construction project requires a healthy relationship between architects and contractors. The architect is responsible for the initial design and layout of the building, as well as overseeing that all work is completed according to their vision. The contractors are responsible for the actual process of building the structure itself.

These two job responsibilities go hand-in-hand and both need to work with each other in order for a project to finish on-time. It is important to have a good working relationship between architects and contractors for the following reasons:

  • It helps the construction project to run smoothly and efficiently.
  • It will minimise stress for both teams.
  • It will ensure effective communication throughout the project.
  • It will minimise disagreements and delays.
  • It can help to guarantee more work for both teams in the future.

Sometimes the relationship between architects and contractors is hostile. When these two teams do not agree with one another, it can cause severe problems for a project. It can lead to miscommunications, which then leads to building delays and additional expenses. Here are some tips that will help to strengthen the relationship between architects and contractors.

1. Know each other’s needs and priorities

Different teams have different priorities when it comes to construction projects. Architects and contractors have different skills and tasks that they need to complete as quickly as possible. An architect is focused on the design concept and whether the actual building is constructed according to his or her design. A contractor will prioritise deadlines, the supply chain and his or her employees.

Recognise these differences and understand that conflict can come from one team’s priorities being neglected. Architects need to understand that contractors have more to worry about than the exact design of the building. Contractors need to understand that building according to the architect’s design will ensure that everything fits and that there are no delays.

2. Address budget and cost problems as soon a possible

One of the biggest causes of disagreements on a building site is budgetary disputes. An architect will often design a building with the functionality and look in mind. A contractor will be more concerned with keeping costs to a minimum. This often results in disputes as the architect will want premium quality finishings, but the contractor will want to reduce costs wherever possible.

When it comes to budgets and financial problems, architects and contractors don’t often see eye-to-eye. But the two teams need to work with each other to find a common solution as soon as possible. The architect and the contractor need to agree with one another and address budgetary concerns early in the process. Working as a team will ensure the success of the project.

3. Communicate openly and often

In any working relationship, communication is key. Architects and contractors need to openly discuss issues and concerns without fear. This will help to strengthen the partnership and build trust. Open communication relies on honesty and understanding. Both teams need to be absolutely clear with one another when it comes to resources, budgets and capabilities.

These three simple points should be kept in mind when working with other teams on a construction project. They will help architects and contractors to work alongside each other happily and efficiently. By leaning on a good relationship, a building project will run smoothly and with minimal delays. This helps to keep costs down and will allow the project to be completed on time.
