What is Foam Concrete and CLC Blocks

What exactly is Foam Concrete and CLC Blocks?

CLC blocks are made of foam concrete. In this article, we'll explore the different kinds of foam concrete as well as how they are utilized. Also, we will learn about their density and strength. Concrete blocks that are emulsified are costly and have some limitations. Contrary to conventional concrete blocks, CLC blocks are more affordable and require less capital investment. Moreover, they are more robust than concrete blocks of the conventional variety. However, the initial amount required to start a CLC plant is much lower than the cost of aerated concrete plants.

The foam cement is what?

Foam concrete is a type of lightweight concrete which has at least 20% foam. It is also known in the industry as Low Density Cellular Concrete or Lightweight Cellular Concrete. It is a cement-based slurry which must have at least 20% foam to be considered a foam concrete. This kind of concrete is a great option for construction projects of all kinds since it saves in terms of time and expense.

This lightweight concrete comes with a compressive force of between 5-8 MPa. It has a density around 1000 kg/m3. It is a great material for building a home because it's strong and offers insulation. The lightweight concrete is normally made using a slurry of fly ash and cement, unlike other brands that use pure cement and water with foaming agents.

Another advantage in foam concrete lies in the fact it doesn't require compacting. The material sticks to the lines of the subgrade. Thus, it can be pumped far distances at a low pressure. It is also very durable and won't break down. However, foam concrete has a higher price than regular concrete.

Another advantage that foam concrete has is that they can reduce the weight of structures by as much as 88%. Because of the air content of the material the air bubbles are evenly all over the body of the concrete. The size of the air bubbles can vary from 0.1 to one millimeter. Density of concrete foam is between 400 to 1600 kg/m3. It's got a very high level of fire resistance . It also serves as an excellent thermal and acoustic insulation. Another benefit to foam concrete is it needs no compaction or vibration.

Where can CLC blocks employed?

Cellular Lightweight Concrete (CLC) blocks have a variety of advantages over regular concrete blocks. These lightweight bricks possess a lower density because of their low aggregate and cement contents, and are more suitable in thermal and sound insulation. Furthermore, they are of wider shape and size than traditional clay bricks. In the past recycling plastic and glass wastes were utilized as cement additives that could improve the compressive strength. It is important to note that the particle size of glass should be less than 45 millimeters in order to function as a substitute for cement.

Typically, CLC blocks are manufactured using a foaming agent that is mixed with water and air. This mixture is pouring into moulds. After it is poured, the concrete mixture needs between 18 and 24 hours for it to cure. In some cases steam curing is utilized to reduce the curing time. This type of curing will give you a higher quality finish.

CLC blocks are made of polypropylene micro fibers. The fibers offer a dependable alternative to clay bricks and are a good choice for affordable housing. In addition, polypropylene micro fibers enhance the performance of brick and masonry. The resulting product has an average density of 2.8 N/m2 this is significantly higher than the average brick or concrete.

CLC blocks are environment friendly. Since the blocks are made out of waste materials, they are free of hazardous chemicals and do NOT emit any pollutants to the environment. Furthermore, they're great insulations and help decrease the dead load of an entire building. They save money on energy and construction materials for home owners.

The strength and density of foam concrete

The strength and density of foam concrete may depend on the type of material used. Most commonly, foam concrete is made up of cement as well as an aerogel. Because of its composition, 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 in order to improve its stiffness and strength.

High temperatures can cause cracks in concrete foam. The higher the temperature, the greater cracks that will form. Concrete with 1000 kg/m3 of density will have about one sixth the thermal conductivity in normal concrete. So, reducing the quantity of concrete can decrease the energy conductivity in the form of 0.04 W/mK.

Additionally, since foamed concrete is an entirely new material, it is not yet covered by standards for testing it. So, the method of preparing the specimens and testing them was based in the same way as tests for normal concrete. For instance, the compression strength of the concrete was determined as per PN EN 12390-3:2011 AC:2012, while the modus of elasticity of the concrete was determined in accordance with the Instruction of the Research Building Institute No. 194/98. The density of the foam was also calculated using PN EN 12390-5.

A concrete's durability and hardness are determined by the proportion of foam that is present in the mortar. Its mix is composed of lower mass aggregates such as expanded clay pumice, vermiculite and so on. The density of concrete is critical because it can affect its strength, permeability, and thermal properties. The amount of additives can modify the properties of a concrete.
