What exactly is Foam Concrete and CLC Blocks?

CLC blocks are constructed of foam concrete. In this article, we'll know more about the various types of foam concrete as well as how they can be used. Additionally, we will discuss their density and strength. Aerated concrete blocks are expensive and come with some limitations. Comparatively to conventional concrete blocks, CLC blocks are more affordable and have a smaller costs of capital. Furthermore, they are more robust than concrete blocks of the conventional variety. But, the initial investment needed to begin CLC plant CLC plant is lower than that of aerated plants.

How do you define foam concrete?

Foam concrete is a sort of lightweight concrete that contains a minimum of 20 percent foam. It is also known for its low Density Cellular Concrete, or Light-weight Cellular Concrete. It is a slurry made of cement that has to contain at the least 20% foam in order to qualify to be considered foam concrete. This type of concrete is a fantastic option for construction projects of all kinds as it helps save money on labor and cost.

The lightweight concrete has a compressive force of between 5-8 MPa and a density of around 1000 kg/m3. It is a great material to build houses because it can be used for strength as well as insulation. The lightweight concrete is normally made using a slurry of cement or fly ash, but some companies use pure cement as well as water with foaming agents.

Another benefit with foam concrete is that it does not require compacting. It adheres to the patterns of subgrade. In turn, it can be pumped across long distances at a low pressure. It's also very strong and will not degrade. However, foam concrete costs more than ordinary concrete.

Another benefit from foam concrete is that it is able to reduce the structure's weight by as much as 88%. Due to its air content that is evenly distributed throughout the material. The size of the air bubbles can vary from 0.1 to one mm. The density of foam concrete can range between 400 to 1600 kg/m3. It's got a very high level of fire resistance , and is a good acoustic and thermal insulation. Another benefit to foam concrete is it requires little or no compaction.

Where can CLC blocks employed?

Cellular Lightweight Concrete (CLC) blocks have numerous advantages over the traditional concrete blocks. These lighter bricks have a low density due to their low aggregate and cement content. They are also better in thermal and sound insulation. In addition, they come with a larger shape and size than traditional clay bricks. In previous studies they used recycled plastics and glass wastes have been used as cement additives in order to increase compressive strength. It is important to know that the size of the particles in glass must be smaller than 45 mm for it to be efficient as a cement substitute.

In general, CLC blocks are manufactured by using a foaming agent which is mixed with water and air. The mix is then and poured into molds. After being poured, the concrete mixture needs between 18 to 24 hours to set. In some cases, steam curing is used to speed up the curing process. This method of curing improves the look.

CLC blocks are made of polypropylene micro fibers. These fibers provide a reliable alternative for clay bricks. They are an ideal option for low-cost housing. Furthermore, polypropylene fibers help improve the peak performance of brick and masonry. The end product is characterized by a density of approximately 2.8 N/m2 and is greater than the average brick or concrete.

CLC blocks are also environment friendly. Since they are made from waste materials they are not contaminated by harmful chemicals , and they do not discharge pollutants into the surroundings. Furthermore, they're excellent insulators and can help reduce dead loads of buildings. They help save money on building materials and power bills for house owners.

strength and density of foam concrete

The strength and density of foam concrete could be different depending on the kind of material employed. It is generally believed that foam concrete comprises cement as well as an aerogel. Due to its composition, foam concrete is susceptible to shrinkage in chemical form. To minimize this, the mixture is controlled by one or two layers of reactive concrete and mechanical connectors. In addition, additional substances can be added to the mix to increase its rigidity and strength.

High temperatures can cause cracks in foam concrete. The greater in temperature more cracks are likely to occur. A concrete sample having 1,000 kg/m3 of density has about one sixth of the thermal conductivity as a normal concrete. In turn, reducing the quantity of concrete can decrease the heat conductivity to 0.04 W/mK.

Furthermore, because foamed concrete was a relatively new material, there aren't tests that are standard for it. So, the method for making specimens and testing it was based on the procedures for normal concrete. For example, the compression strength of the concrete was determined as per PN EN 12390-3:2011 AC:2012. Additionally, the Modulus of Elasticity was calculated according to the Instructions for the use of the Research Building Institute No. 194/98. In the same test, density also measured using PN-EN 12390-5:2011.

Density and strength of concrete made from foam is determined by the proportion of foam present in the mortar. Its composition is composed of low-mass aggregates like expanded clay, vermiculite, as well as pumice. The density of concrete is important as it affects the strength of it, its permeability and even its thermal performance. The amount of admixtures can also drastically change its properties.
