What is Foam Concrete and CLC Blocks
What exactly is Foam Concrete and CLC Blocks?
CLC blocks are made up of foam concrete. In this article, we'll learn more about the types of foam concrete as well as the places they can be used. We will also discuss their strength and density. Concrete blocks that are emulsified are costly and are subject to certain limitations. In comparison to conventional concrete blocks, CLC blocks are more affordable and have a smaller expense of capital. Furthermore, they are more durable than traditional concrete blocks. But, the initial investment required to start a CLC plant is less than the cost of aerated cement plants.
How do you define foam concrete?
Foam concrete is a sort of concrete with a lightweight structure that has at least 20 percent of foam. It is also known also as Low Density Cellular Concrete or L-C Concrete. It is a cement-based slurry which must be composed of at least 20% of foam to be considered as foam concrete. This kind of concrete is an ideal alternative for numerous construction projects as it will save on labor costs and other expenses.
This lightweight concrete has a compressive strength between 5-8 MPa, and a density of approximately 1000 Kg/m3. It can be used for building a home because it can provide strength and insulation. The concrete that is lightweight is usually produced using a mixture of fly ash or cement while other vendors will use only pure cement and water with a foaming ingredient.
Another benefit with foam concrete is that it does not need to be compacted. It adheres to the contours of the subgrade. Thus, it can be pumped far distances at a low pressure. It's also extremely long-lasting and doesn't degrade. However, it has a higher price than regular concrete.
Another benefit of foam concrete is that it can reduce the structure's weight by up to an 80%. Due to the air content of the material it is possible to have air bubbles evenly spread throughout the concrete. The size of these air bubbles can vary from 0.1 to one mm. Density of concrete foam is between 400 and 1600 kg/m3. It's got a very high level of fire resistance . It's also an excellent thermal and acoustic insulator. Another advantage for foam concrete is the fact that it needs zero compaction or vibrating.
Where can CLC blocks utilized?
Cellular Lightweight Concrete (CLC) blocks offer a number of advantages over solid concrete blocks that are typically used. The lightweight bricks have low density due to their low aggregate and cement content. They are also more effective in thermal and sound insulation. The bricks also come in a larger shape and size than traditional clay bricks. In past studies in the past, recycled plastic and glass wastes were utilized as cement additives that could improve the compressive strength. It is imperative to realize that the size of the particles in glass should be less than 45 mm for it to be effective as a substitute for cement.
Most often, CLC blocks are manufactured using a foaming agent that is combined with water and air. This mix is then and poured into moulds. Once the concrete is poured into the moulds, the mixture will take between 18 and 24 hours to harden. In certain cases steam curing can be used in order to shorten the curing time. This curing method also gives a more polished finishing.
CLC blocks are constructed of polypropylene micro fibers. These fibers provide a reliable alternative for clay bricks. CLC blocks are an ideal choice for affordable housing. Furthermore, polypropylene microscopic fibers improve the peak behaviour of masonry and bricks. The resulting product has a density of about 2.8 N/m2 which is much higher than that of conventional concrete or brick.
CLC Blocks are environmental friendly. Since they are made using waste materials, the blocks are free of damaging chemicals and release harmful substances into the environment. Furthermore, they are good insulators and reduce the dead load of an entire building. They also help to save money on energy and construction materials for house owners.
strength and density of foam concrete
The strength and density of foam concrete can vary based on the type of material that is used. Most commonly, foam concrete is made up of cement as well as an aerogel. Due to its composition foam concrete is susceptible to chemical shrinkage. To limit this, the mix is kept in check with one or two layers of reactive concrete and mechanical connectors. The addition of additional materials to the mix in order to improve its strength and stiffness.
High temperatures can cause cracks in concrete foam. The greater that temperature is the more cracks may occur. A concrete sample that has an average density of 1000 kg/m3 has roughly one-sixth the thermal conductivity in normal concrete. Accordingly, reducing its density will decrease the heat conductivity to 0.04 W/mK.
Furthermore, because foamed concrete was a relatively new material, there isn't standards for testing it. As a result, the process of making samples and testing them was based upon procedures of ordinary concrete. For example, the compression strength of the concrete was measured as per PN EN 12390-3:2011 AC:2012. Furthermore, the modus of elasticity of the concrete was calculated in accordance with the Instruction by the Research Building Institute No. 194/98. This foam's density is measured using PN-EN 12390-5:2011.
A concrete's durability and hardness are dependent on the proportion of foam in the mortar. Its structure is made up of low-mass aggregates like expanded clay, pumice, and vermiculite. The density of concrete is important as it affects its strengthas well as its permeability the thermal properties, and strength. Additive amounts can be a major influence on the properties.
