What is Foam Concrete and CLC Blocks

What is Foam Concrete and CLC Blocks?

CLC blocks are made up of foam concrete. In this article we will know more about the various types of foam concrete along with the areas they are utilized. We will also learn about their density and strength. Aerated concrete blocks can be expensive as well as have limitations. Comparatively to conventional concrete blocks, CLC blocks are more accessible and come with a lower capital investment. In addition, they're more robust than concrete blocks of the conventional variety. However, the initial cost necessary to start an CLC plant is lower than that of aerated plants.

What is foam concrete?

Foam Concrete is a kind of concrete that is lightweight and contains a minimum of 20 percent of foam. It is also referred to as low Density Cellular Concrete, or light-weight cellular concrete. It is a slurry made of cement which must contain at least 20% of foam to be considered foam concrete. This kind of concrete is a good choice for many construction projects as it will save on costs and labor.

The lightweight concrete has a compressive strength of 5-8 MPa and a density approximately 1000 Kg/m3. It is a great material to build a house because it offers both strength and insulation. The lightweight concrete is normally created using a slurry made of fly ash or concrete, however, some vendors use the pure cement along with water that has the addition of a foaming component.

Another advantage for foam concrete is the fact that it does not need to be compacted. The material sticks to the patterns of subgrade. As a result, it can be pumped far distances, but with a very low pressure. It's also very strong and won't break down. However, it can be more costly than normal concrete.

Another advantage with foam concrete that it is able to reduce the weight of a structure by up to an 80%. Because of its air content there are air bubbles that are evenly distributed throughout the concrete. The size of the air bubbles can vary between 0.1 to one millimeter. Density of concrete foam can range between 400 and 1600 kg/m3. It offers a high level of fire resistance , and is a good acoustic and thermal insulator. Another benefit to foam concrete is it needs zero compaction or vibrating.

Where are CLC blocks utilized?

Cellular Lightweight Concrete (CLC) blocks have numerous advantages over the traditional concrete blocks. These bricks that are lightweight have a lower density because of their low cement and aggregate levels, and they are better for sound and thermal insulation. In addition, they come with a larger design and dimension than traditional clay bricks. In the past the use of recycled plastic and glass materials were used as cement additives that could improve the compressive strength. It is important to know that the size of the particles in glass should be less than 45 millimeters to be effective as a cement substitute.

Typically, CLC blocks are manufactured using a foaming ingredient that is mixed with water and air. The mixture is then and poured into moulds. After being poured, the concrete mixture requires between 18 and 24 hours for it to cure. In certain cases steam curing is utilized to speed up the curing process. This kind of curing helps to give a better final appearance.

CLC blocks are manufactured using polypropylene microfibers. They provide a solid alternative to clay bricks . It is an ideal option for low-cost housing. Additionally, polypropylene micro fibers boost the peak performance of brick and masonry. The final product has a density of approximately 2.8 N/m2, which is higher than the typical concrete or brick.

CLC Blocks are environment green. Since they are made from waste materials, they are free of harmful chemicals and don't release harmful substances into the environment. Additionally, they are also extremely efficient at insulating and reduce the dead load on a building. They save money on building materials and power bills for homeowners.

the strength and density of foam concrete

The strength and density of foam concrete differ based on the type of material used. In general, foam concrete is composed of cement as well as an aerogel. Because of its chemical composition, foam concrete is susceptible to shrinkage in chemical form. In order to minimize this, the mixture is confined by multiple layers or layers concrete and mechanical connectors. Other materials can be added to the mix in order to improve its stiffness and strength.

High temperatures can cause cracks in foam concrete. The greater the temperature, the greater cracks may occur. A concrete slab with 1000 kg/m3 of density has roughly one-sixth the thermal conductivity as a normal concrete. Therefore, reducing the density will decrease the efficiency of thermal radiation by 0.04 W/mK.

Furthermore, because foamed concrete is a brand new substance, there aren't established test methods that can be used to test it. As a result, the process of making samples and testing their properties was based off procedures to test ordinary concrete. For instance, the compression strength of the concrete was measured by PN-EN-12390-3:2011 plus AC:2012. Meanwhile, the degree of flexibility was measured by reference to the instructions from the Research Building Institute No. 194/98. The foam's density was determined 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 such as expanded clay vermiculite, and pumice. The density of a concrete is vital because it affects its strengthas well as its permeability in addition to its thermal and mechanical properties. The amount of admixtures in the concrete can alter the properties of the concrete.
