CLC blocks are made of foam concrete. In this article we will know more about the various types of foam concrete along with the areas they can be used. In addition, we will know their strength and density. Aerated concrete blocks are expensive and have certain limitations. In comparison to conventional concrete blocks, CLC blocks are more economical and require a lesser cost of capital investment. In addition, they're more durable than conventional concrete blocks. However, the initial investment necessary to start a CLC plant is less than the cost of aerated cement plants.
Foam concrete is a form of concrete that is lightweight and contains a minimum of 20% foam. It is also referred to by the name Low Density Cellular Concrete or lightweight cellular concrete. It is a cement-based slurry that must contain at minimum 20% foam to be considered a foam concrete. This type of concrete is an ideal alternative for numerous construction projects as it is able to save on both labor and expenses.
This lightweight concrete has a compressive strength that ranges from 5-8 MPa with a density of around 1000 Kg/m3. It is a great material for building a home because it has strength and insulation. This lightweight concrete is usually produced using a mixture of cement or fly ash, but some companies use only pure cement and water with an ingredient that foams.
Another benefit in foam concrete lies in the fact it doesn't need to be compacted. The material is able to adhere to lines of the subgrade. Because of this, it can be pumped far distances using relatively little pressure. It's also extremely strong and doesn't degrade. However, foam concrete has a higher price than regular concrete.
Another advantage for foam concrete is that it is able to reduce the structure's weight by up to 88%. Because of the air content of the material there are air bubbles that are evenly scattered throughout the concrete. The size of these air bubbles can range from 0.1 to one mm. Its foam concrete density ranges between 400 to 1600 kg/m3. It has a high level of fire resistance and is a good acoustic and thermal insulation. Another benefit for foam concrete is the fact that it requires minimal compaction or vibration.
Cellular Lightweight Concrete (CLC) blocks are superior to conventional concrete blocks. The lightweight bricks have low density due to their low aggregate and cement content, and are better in thermal and sound insulation. The bricks also come in a larger design and dimension than traditional clay bricks. In previous studies recycled plastic and glass scraps were used as cement additives to increase the compressive strength. It is important to know that the size of the particles in glass must be less than 45 millimeters for it to function as a substitute for cement.
Usually, CLC blocks are manufactured with a foaming agent that is combined with air and water. This mixture is then directly put into moulds. When it's poured in, the mixture needs between 18 and 24 hours before it is able to solidify. In some instances steam curing can be employed to speed up the curing process. This method of curing can provide a better quality look.
CLC blocks are constructed from polypropylene micro fibers. They are a reliable alternative for clay bricks. They are an ideal option to build low-cost homes. In addition, polypropylene micro fibers enhance the performance of brick and masonry. The final product has an approximate density of 2.8 N/m2 this is significantly higher than concrete or brick.
CLC Blocks can be described as environment green. Since the blocks are made out of recycled materials, they are free of harmful chemicals , and they do not emit any pollutants to the environment. They are also good insulators and lower the dead load of a structure. They help reduce the cost of energy bills and construction materials for homeowners.
The strength and the density of foam concrete depend on the type of material employed. In general, foam concrete is composed of cement as well as an aerogel. Because of its nature, foam concrete is susceptible to shrinkage in chemical form. To limit this, the mix is held in check by 2 or 3 layers of physically reactive powder concrete as well as mechanical connectors. Additionally, other materials can be added to the mix to increase its stiffness and strength.
The high temperatures can cause cracks in foam concrete. The greater heat, greater cracks that will form. A concrete material with 1,000 kg/m3 of density has approximately one sixth of the thermal conductivity of a normal concrete. Consequently, reducing the density will reduce the energy conductivity in the form of 0.04 W/mK.
Furthermore, because foamed concrete is still a relatively new substance, there aren't any standardized test procedures for it. Therefore, the method of preparing the specimens and testing them was based in the same way as tests that are used for conventional concrete. For example, the compression strength of the concrete was determined using PN-EN12390-3:2011 + AC:2012. Meanwhile, the elastic modulus was determined in accordance with the Instruction by the Research Building Institute No. 194/98. It was assessed using the PN-EN12390-5:2011.
Strength and densities of the foam concrete are determined by the proportion of foam in the mortar. Its mix is composed of lower mass aggregates like expanded clay, pumice, and vermiculite. The density of concrete is critical because it can impact the strength and permeability along with its thermal property. The amount of admixtures in the concrete can modify the properties of a concrete.
