What is Foam Concrete and CLC Blocks?

CLC blocks are composed of foam concrete. In this article we will be able to learn more about the forms of foam concrete and how they are used. We will also discuss their strength and density. Aerated concrete blocks are expensive and are subject to certain limitations. If compared with conventional concrete blocks, CLC blocks are more affordable and require less cost of capital. Additionally, they are more durable than traditional concrete blocks. However, the initial investment required to build CLC plants CLC plant is less than that of aerated concrete plants.

Do you know what foam concrete means?

Foam Concrete is a kind of concrete that is lightweight and contains at least 20 percent of foam. It is also referred to as low Density Cellular Concrete, or Light-weight Cellular Concrete. It is a cement-based slurry that has to contain at the least 20% of foam to be considered as foam concrete. This kind of concrete is a great option for a variety of construction projects as it will save on labor costs and other expenses.

The concrete is lightweight and has a compressive strength of between 5-8 MPa and an density of approximately 1000 kg/m3. It is a great material to construct a house since it can provide strength and insulation. This lightweight concrete is usually made using a slurry of cement or fly ash, but some companies use only pure cement and water with an ingredient that foams.

Another benefit from foam concrete is that the material doesn't need to be compacted. The material adheres to the lines of the subgrade. In turn, it is able to be pumped over long distances with very little pressure. It's also very strong and doesn't degrade. However, foam concrete tends to be more costly ordinary concrete.

Another advantage for foam concrete is the fact that it can reduce the weight of a structure by as much as 80%. Due to its air content that is evenly distributed throughout the material. The size of these air bubbles can range from 0.1 to one millimeter. The density of foam concrete can range between 400 to 1600 kg/m3. It is extremely resistant to fire. of fire resistance . It is an excellent thermal and acoustic insulator. Another benefit with foam cement is that it needs minimal compaction or vibration.

Where can CLC blocks employed?

Cellular Lightweight Concrete (CLC) blocks have a variety of advantages over the traditional concrete blocks. The lightweight bricks have lower density because of their lower aggregate and cement amount, and also are better in thermal and sound insulation. They also have a larger dimensions and shape than conventional clay bricks. In past studies that used recycled plastic as well as glass wastes have been used as cement additives to boost compressive strength. It is important to remember that the size of the particles in glass should not exceed 45 millimeters to be effective as a cement substitute.

Most often, CLC blocks are manufactured with a foaming agents that is combined with water and air. The mix is then placed in moulds. After it is poured, the concrete mixture needs between 18 and 24 hours to fully harden. In some cases steam curing is employed to reduce the curing time. This kind of curing can provide a better quality final appearance.

CLC blocks are manufactured using polypropylene microfibers. They are a reliable alternative to clay bricks and is an ideal choice for housing that is low-cost. Polypropylene micro fibers boost the peak performance of masonry and bricks. The product that is created has A density of 2.8 N/m2 this is significantly higher than the normal concrete or brick.

CLC block are environmentally friendly. Because the blocks are constructed using waste materials, the blocks are free of hazardous chemicals and do NOT release pollutants into the atmosphere. Furthermore, they are great insulations and help reduce dead loads of the building. They save on energy and construction materials for house owners.

The strength and density of foam concrete's strength and density

The strength and density of foam concrete depend on the type of material used. The majority of foam concretes contain cement and an aerogel. Because of its structure, foam concrete is susceptible to chemical shrinkage. To prevent this, the mix is secured with multiple layers or layers concrete and mechanical connectors. Add additional materials to the mix to increase the stiffness and strength.

The high temperatures can cause cracks in foam concrete. The greater that temperature is the greater cracks could occur. A concrete sample with 1,000 kg/m3 of density has around one sixth of the thermal conductivity that is found in a normal concrete. So, reducing the density will reduce the heating conductivity by 0.04 W/mK.

In addition, because foamed concrete is a brand new material, there are no established test methods that can be used to test it. So, the process of making samples and testing they were based on tests that were used for standard concrete. For example, the compression strength of the concrete was measured using PN-EN12390-3:2011 + AC:2012, whereas the coefficient of elastic modulus measured as per the Instruction by the Research Building Institute No. 194/98. Diet of the foam was also determined using PN -EN 12390-5.

In the strength and volume of foam concrete, it are dependent on the percentage of foam that is present in the mortar. Its components are composed of low-mass aggregates like expanded clay vermiculite, and pumice. The density of concrete is vital because it may affect the strength of it, its permeability, along with its thermal property. Additive amounts can alter the properties of the concrete.
