What is Foam Concrete and CLC Blocks?

CLC blocks are made from foam concrete. In this article, we’ll know more about the various types of foam concrete and where they are utilized. We will also discuss their strength and density. Aerated concrete blocks can be expensive and have certain limitations. As compared to conventional concrete block, CLC blocks are more accessible and come with a lower expense of capital. Moreover, they are more durable than traditional concrete blocks. However, the initial cost needed to begin CLC plant CLC plant is lower than that required for aerated plants.

Do you know what foam concrete means?

Foam Concrete is a kind of lightweight concrete that contains a minimum of 20 percent foam. It is also known by the name Low Density Cellular Concrete, or L-C Concrete. It is a cement-based slurry that must contain at minimum 20% foam in order to be considered to be foam concrete. This kind of concrete is an ideal option for many construction projects as it is able to save on costs and labor.

This concrete lightweight has a compressive strength ranging from 5-8 MPa with a density of about 1000 kg/m3. It is a great material to construct houses since it can provide strength and insulation. The lightweight concrete is typically created with a slurry of fly ash or cement unlike other brands that use pure cement and water , along with foaming substances.

Another benefit over foam cement is that it doesn’t need to be compacted. The material bonds to patterns of subgrade. In turn, it is able to be pumped for extended distances using a relatively low pressure. It’s also extremely durable and doesn’t degrade. However, it costs more than normal concrete.

Another advantage with foam concrete that the material can reduce the structure’s weight by as much as an 80%. Due to the air content of the material the air bubbles are evenly spread throughout the concrete. The size of the air bubbles can range between 0.1 to one mm. Density of concrete foam can range between 400 and 1600 kg/m3. It has a high degree of fire resistance . It’s also an excellent thermal and acoustic insulator. Another advantage in foam concrete lies in the fact it needs zero compaction or vibrating.

Where are CLC blocks used?

Cellular Lightweight Concrete (CLC) blocks have several advantages over solid concrete blocks that are typically used. The lightweight bricks have lower density because of their low aggregate and cement content. They also perform better for sound and thermal insulation. They also have a larger form and larger size than traditional clay bricks. In the past recycling plastic and glass scraps were used as cement additives for enhancing compressive strength. It is essential to keep in mind that the particle size of glass must not exceed 45 millimeters for it to be efficient as a cement substitute.

In general, CLC blocks are manufactured using a foaming ingredient that is combined with water and air. This mixture is later dumped into molds. After the moulds are filled, the concrete mixture will take between 18 and 24 hours before it is able to solidify. In certain cases the use of steam curing to reduce the curing time. This type of curing gives a more polished look.

CLC bricks are made from polypropylene micro fibers. They provide a solid alternative to clay bricks . It is an ideal choice for affordable housing. Furthermore, polypropylene fibers help improve the peak performance of masonry and bricks. The resulting product has an average density of 2.8 N/m2 and is greater than concrete or brick.

CLC blocks are also ecologically green. Since the blocks are made out of recycled materials, they are free of harmful chemicals , and they do not emit harmful pollutants into the air. They are also great insulators and help to decrease the dead load of a building. They are a great way to save money on energy bills and construction materials for home owners.

the strength and density of foam concrete’s strength and density

The strength and densities of foam concrete depend on the type of material that is used. The majority of foam concretes contain cement as well as an aerogel. Due to its composition, foam concrete is prone to shrinkage in chemical form. To limit this, the mix is confined by 2 or 3 layers of physically reactive powder concrete and mechanical connectors. Additional materials can be added to the mix to increase its rigidity and strength.

Cracks can form when temperatures rise in concrete foam. The greater heat, more the cracks will occur. A concrete sample that has 1000 kg/m3 of density will have about one sixth the thermal conductivity as a normal concrete. Thus, reducing amount of density decreases the heating conductivity by 0.04 W/mK.

Additionally, since foamed concrete was a relatively new product, there’s not tested methods that have been developed for it that are standardized. In the end, the procedure of making the specimens for testing their properties was based off procedures for regular concrete. For example, the compression strength of the concrete was measured according to PN – EN 12390-3 :2011 + AC:2012, while the flexibility modulus was calculated according to the instructions from the Research Building Institute No. 194/98. It was also determined by using PN-EN-12390-5:2011.

Its strength as well as density is dependent on the amount of foam in the mortar. Its composition consists of low-mass aggregates, such as expanded clay pumice, vermiculite and so on. The density of concrete is critical because it may affect the strength, the permeability along with its thermal property. The quantity of admixtures used can modify the properties of a concrete.
