What exactly is Foam Concrete and CLC Blocks?

CLC blocks are constructed of foam concrete. In this article, we'll be able to learn more about the forms of foam concrete, as well as where they can be used. In addition, we will know their strength and density. Aerated concrete blocks can be expensive and are subject to certain limitations. Compared to conventional concrete blocks, CLC blocks are more affordable and require less capital investment. Furthermore, they are more robust than concrete blocks of the conventional variety. However, the initial amount needed to begin a CLC plant is less than that required for aerated plants.

Do you know what foam concrete means?

Foam concrete is a sort of lightweight concrete that contains at least 20% foam. It is also referred to for its low Density Cellular Concrete or Leichter Cellular Concrete. It is a slurry made of cement that must have at least 20% foam before it can be considered as foam concrete. This kind of concrete can be a wonderful option for construction projects of all kinds as it helps save on both labor and expenses.

This lightweight concrete can be found with a compressive strength ranging from 5-8 MPa. Its density is approximately 1000 Kg/m3. It can be used to build homes since it can provide strength and insulation. It is generally constructed using a mix of fly ash or cement, unlike other brands that use pure cement and water , along with an ingredient that foams.

Another benefit for foam concrete is the fact that it does not require compacting. The concrete sticks to the surface contours and lines that the subgrade. Because of this, it can be pumped far distances with very little pressure. It's also very strong and won't break down. However, it costs more than normal concrete.

Another advantage with foam concrete that it can reduce the weight of structures by as much as up to 80%. Because of its air content air bubbles are evenly all over the body of the concrete. The size of these air bubbles can vary from 0.1 to 1 millimeter. Foam concrete's density can range between 400 and 1600 kg/m3. It has a high degree of fire resistance . It's also a good acoustic and thermal insulator. Another benefit for foam concrete is the fact that it demands minimal compaction or vibration.

Where are CLC blocks utilized?

Cellular Lightweight Concrete (CLC) blocks have numerous advantages over the traditional concrete blocks. The lightweight bricks have lower density because of their low aggregate and cement content. They are also more effective for sound and thermal insulation. The bricks also come in a larger form and larger size than traditional clay bricks. In the past, recycled plastic and glass scraps were used as cement additives, which improved the compressive strength. It is important to remember that the size of the particles in glass must be less than 45 millimeters in order to be effective as a cement substitute.

In general, CLC blocks are manufactured using a foaming agent that is mixed with water and air. This mixture is then directly put into molds. When it's poured in, the mixture needs between 18 to 24 hours to set. In some cases steam curing may be utilized for reducing the time required to cure. This method of curing offers a superior finishing.

CLC blocks are constructed of polypropylene micro fibers. The fibers offer a dependable alternative to clay bricks and are an ideal option to build low-cost homes. In addition, the polypropylene fibers increase the performance of masonry and bricks. The resulting product has the density of 2.8 N/m2 which is more than the average concrete or brick.

CLC block are eco green. Since the blocks are made of waste materials, they are free of harmful chemicals and do not emit any pollutants to the environment. In addition, they're fantastic insulators that help lessen the dead load in buildings. They save on building materials and energy costs for homeowners.

The strength and density of foam concrete's strength and density

The strength and density of foam concrete can vary based on the type of material used. The most common ingredient in foam concrete is cement as well as an aerogel. Because of its nature, foam concrete is susceptible to shrinkage in chemical form. In order to limit this, the mix is kept in check with one or two layers of reactive powder concrete and mechanical connectors. Further materials can be added to the mix in order to improve its rigidity and strength.

Temperatures that are high can cause cracks in concrete foam. The higher heat, more cracks could occur. A concrete slab with the density of 1000 kg/m3 contains about one-sixth the thermal conductivity of normal concrete. As a result, reducing the density of the concrete will reduce its heat conductivity to 0.04 W/mK.

Additionally, since foamed concrete is a brand new material, there are no standard test procedures for it. As a result, the procedure for preparing samples 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 in accordance with PN-EN 12390-3:2011 and AC:2012. Meanwhile, the flexibility modulus was determined in accordance with the instructions for the use of the Research Building Institute No. 194/98. It was identified using PN.EN. 12390-5.2011.

Density and strength of concrete made from foam are dependent on the amount of foam in the mortar. Its composition consists of low-mass aggregates, such as expanded clay pumice, and vermiculite. The density of concrete is significant because it influences its strength, permeability also thermal qualities. The amount of additives can be a major influence on the properties.
