What is Foam Concrete and CLC Blocks

What exactly is Foam Concrete and CLC Blocks?

CLC blocks are made of foam concrete. In this article, we'll learn more about the types of foam concrete and how they are used. We will also learn about their strength and density. Concrete blocks that are emulsified are costly and have certain limitations. Contrary to conventional concrete blocks, CLC blocks are more economical and require a lesser cost of capital investment. Moreover, they are more durable than conventional concrete blocks. The initial investment required for establishing one CLC plant is much lower than the aerated concrete plants.

Foam concrete is what it is.

Foam concrete is a type of concrete with a lightweight structure that has at least 20% foam. It is also referred to also as Low Density Cellular Concrete, or Light-weight Cellular Concrete. It is a cement-based slurry that has to contain at the least 20% foam in order to qualify to be considered to be foam concrete. This kind of concrete is an ideal option for construction projects of all kinds as it helps save on both labor and expenses.

This lightweight concrete has a compressive strength between 5-8 MPa. It has a density about 1000 kg/m3. It is a great material to build homes since it can be used for strength as well as insulation. The concrete that is lightweight is usually created using a slurry made of fly ash or cement, but some companies use pure cement and water with the addition of a foaming agent.

Another advantage from foam concrete is that the material doesn't need to be compacted. The material adheres to the shapes of the subgrade. It is able to be pumped over long distances with relatively little pressure. It's also extremely strong and will not degrade. However, foam concrete costs more than normal concrete.

Another advantage in foam concrete's use is that they can reduce the structure's weight by up to up to 80%. Due to its air content that is evenly dispersed throughout the material. The size of these air bubbles can range between 0.1 to one mm. In terms of density, foam concrete is between 400 and 1600 kg/m3. It offers a high level of fire resistance . It is a good acoustic and thermal insulation. Another benefit from foam concrete is that it needs little or no compaction.

Where can CLC blocks used?

Cellular Lightweight Concrete (CLC) blocks offer a number of advantages over solid concrete blocks that are typically used. They have a low density due to their low aggregate and cement content. They are also better for sound and thermal insulation. They also have a larger dimensions and shape than conventional clay bricks. In the past, recycled plastic and glass scraps were used as cement additives for enhancing the compressive strength. It is important to note that the particle size of glass needs to be less that 45 mm for it to function as a cement substitute.

Usually, CLC blocks are manufactured using a foaming ingredient that is mixed with water and air. This mixture is later placed into moulds. When it's poured in, the mixture will take between 18 and 24 hours for the mixture to be cured. In certain cases steam curing can be used in order to reduce the curing duration. This method of curing improves the finish.

CLC blocks are made of polypropylene microfibers. They are a reliable alternative for clay bricks. CLC blocks are an ideal option to build low-cost homes. Furthermore, polypropylene fibers can improve the performance of brick and masonry. The final product has A density of 2.8 N/m2 This is significantly more than brick or concrete.

CLC blocks can also be ecologically friendly. Since the blocks are made from waste materials they are not contaminated by toxic chemicals and do not emit harmful pollutants into the air. Additionally, they are also great insulators and help to reduce the dead load of an building. They save on energy and construction materials for homeowners.

Density and strength of foam concrete

The strength and density of foam concrete can be different depending on the kind of material used. In general, foam concrete is composed of cement and an aerogel. Due to its composition foam concrete is susceptible to chemical shrinkage. To prevent this, the mixture is kept in check with the addition of two to three layers of concrete as well as mechanical connectors. The addition of additional materials to the mix in order to improve its strength and stiffness.

The high temperatures can cause cracks in concrete foam. The higher your temperature rises, more cracks could occur. A concrete sample that has a density of 1000 kg/m3 has approximately one sixth of the thermal conductivity of a normal concrete. In turn, reducing the density of the concrete will reduce its thermal conductivity by 0.04 W/mK.

Furthermore, because foamed concrete was a relatively new material, it is not yet covered by tests that are standard for it. As a result, the procedure for preparing samples and testing it was based on the procedures for ordinary concrete. For example, the compression strength of the concrete was measured according to PN-EN 12390-3:2011 + AC:2012. Furthermore, the degree of flexibility was calculated as per the instructions that is part of the Research Building Institute No. 194/98. It was identified using PN.EN. 12390-5.2011.

The strength and density of foam concrete are determined by the proportion of foam that is present in the mortar. Its structure is made up of low-mass aggregates such as expanded clay pumice, vermiculite and so on. The density of concrete is significant because it has an impact on the strength and permeability, as well as thermal characteristics. Amount of admixtures could significantly alter its properties.
