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 discover more about the different types of foam concrete and how they can be used. We will also know about their strength and density. Aerated concrete blocks are expensive and have certain limitations. If compared with conventional concrete blocks, CLC blocks are more affordable and have a lower costs of capital. In addition, they're more durable than conventional concrete blocks. The initial investment required to establish CLC plant CLC plant is less than the cost of aerated concrete plants.
Is foam concrete a thing?
Foam Concrete is a kind made of lightweight concrete, which contains at least 20 percent foam. It is also known as Low Density Cellular Concrete, or Lightweight Cellular Concrete. It is a slurry made of cement that must contain at minimum 20% of foam to be considered foam concrete. This type of concrete is an excellent option for a variety of construction projects as it helps save on both labor and expenses.
The concrete is lightweight and has a compressive strength of 5-8 MPa and an density of approximately 1000 Kg/m3. It is a great material in the construction of a home since it offers both strength and insulation. The lightweight concrete is normally produced using a mixture of fly ash or cement, while other vendors will use pure cement and water , along with the addition of a foaming component.
Another advantage with foam concrete is that it doesn't require compacting. The material bonds to edges of the subgrade. As a result, it can be pumped for long distances at a low pressure. Also, it is extremely durable and does not decompose. However, foam concrete has a higher price than normal concrete.
Another advantage from foam concrete is that they can reduce the weight of structures by as much as 88%. Due to the air content of the material and air bubbles, they are evenly distributed throughout the body of the material. The size of the air bubbles can vary between 0.1 to one millimeter. The density of foam concrete is between 400 and 1600 kg/m3. It's got a very high level of fire resistance . It is an excellent thermal and acoustic insulator. Another benefit of foam concrete is that it requires the least amount of compaction and vibration.
Where are CLC blocks used?
Cellular Lightweight Concrete (CLC) blocks offer a number of advantages over regular concrete blocks. The lightweight bricks have lower density because of their low cement and aggregate content. They are also better for sound and thermal insulation. Additionally, they have a larger dimensions and shape than conventional clay bricks. In the past, recycled plastic and glass materials were used as cement additives, which improved the compressive strength. It is crucial to remember that the particle size of glass needs to be less that 45 millimeters in order to be efficient as a cement substitute.
Usually, CLC blocks are manufactured using a foaming agent that is mixed with air and water. The mixture is then placed in molds. When it's poured in, the mixture needs between 18 and 24 hours to fully harden. In some instances steam curing is utilized in order to shorten the curing time. The method also will give you a higher quality look.
CLC blocks are manufactured using polypropylene micro fibers. These fibers make a durable alternative to clay bricks and are an excellent choice for low-cost housing. Furthermore, polypropylene microscopic fibers help improve the peak performance of brick and masonry. The resultant product has a density of about 2.8 N/m2 which is more than the average concrete or brick.
CLC Blocks can be described as environment green. Since they are made from waste materials, they are not contaminated by harmful chemicals and do not pollute the environment. Furthermore, they're excellent insulators and can help reduce dead loads of a structure. They can save money on energy and construction materials for home owners.
strength and density of foam concrete's strength and density
The strength and density of foam concrete can depend on the type of material that is used. Generallyspeaking, foam concrete has cement and an aerogel. Due to its composition foam concrete is prone to chemical shrinkage. To reduce this, the mixture is restrained with one or two layers of reactive powder concrete and mechanical connectors. Further materials can be added to the mix to increase its stiffness and strength.
The high temperatures can cause cracks in foam concrete. The greater temperatures, the greater cracks will develop. A concrete material with 1000 kg/m3 of density has about one sixth of the thermal conductivity of a normal concrete. As a result, reducing the density reduces the temperature conductivity of the concrete by 0.04 W/mK.
Furthermore, because foamed concrete is a new material, there's no standard test procedures for it. The method of preparing the specimens and testing they were based on tests for regular concrete. For example, the compression strength of the concrete was measured as per PN EN 12390-3:2011 AC:2012. Meanwhile, the degree of flexibility was calculated according to the instructions for the use of the Research Building Institute No. 194/98. The density of the foam was also determined by using PN-EN-12390-5:2011.
Foam concrete's density and strength is dependent on the amount of foam present in the mortar. The composition of the mortar is composed of low-mass aggregates such as expanded clay, vermiculite, and pumice. The density of a concrete is significant because it affects the strength of it, its permeability, the thermal properties, and strength. The quantity of admixtures used can affect the properties of the concrete.
