cellular light weight bricks are a new material for construction industry. It is a type of foam concrete which can be manufactured at building sites by mixing the raw materials in different proportions. It is an environment friendly, energy efficient, and cost efficacious material, which is gaining popularity among builders worldwide.
The CLC is a light weight masonry material, which has a wide range of densities ranging from 400 kg/m3 to 1800 kg/m3. It is fire proof, termite proof, thermally insulated, soundproof and offers an excellent fire rating.
These blocks are lighter in weight compared to clay bricks and concrete blocks, which saves labor costs and enables faster construction. It also reduces the dead load of structures, which makes it easier for the house owners to use less rebar and other concrete materials in their projects.
It is also environmentally friendly, as it uses waste materials that are otherwise difficult to recycle. It is cheaper than traditional concrete bricks, which is the reason why it is increasingly used for walling masonry.
In this study, cellular lightweight concrete bricks were produced using recycled expanded polystyrene aggregate as the main aggregate and commercial Portland cement as the binder. The bricks obtained met the requirements of masonry standards in Mexico.
The tensile strength of the blocks was measured at three, seven, 14 and 28 days. The results showed that the tensile strength increased in all tests. However, the compressive strength decreased after 28 days of aging.
