Cellular Lightweight Concrete Blocks

Unlike burnt clay bricks, Cellular Lightweight Concrete (CLC) blocks are environment-friendly and economical. CLC is a homogeneous combination of cement and silica. It is characterized by lower density and acoustic insulation. It is also fire and pest-resistant. Moreover, it is a versatile material that is utilized as thermal insulation over flat roofs and tunnels.

CLC is manufactured by using a foaming agent. This agent is diluted with water at a ratio of 1:35. It then passes through a foam generator. The resulting foam is stable and can be pumped to a maximum height. The air content is kept at 40 to 80 percent of the total volume.

The size of the foam bubbles varies between 0.1 and 1.5 mm. This material is highly resistant to freezing issues and can be used in a variety of applications. Besides, it is termite-proof. It is also easy to work on.

Low-density CLC is perfect for thermal insulation, which helps to save energy and reduce long-term maintenance costs. It is also ideal for unused cellars and wells. It is a great alternative to dense concrete. It also helps in saving construction expenses.

Fly ash is another major ingredient in CLC. It is a waste product from industries. It is a by-product of the burning process. The addition of fly ash diminishes the cost of construction. The addition of fly ash has no effect on the strength of the structure.

In order to increase acoustic insulation, the density of the CLC is decreased. This can be done by adding an appropriate agent to the mix.
