Concrete Blocks

CONCRETE BLOCKS

Concrete block construction has gained importance and has become a valid alternative to fired clay bricks. Concrete blocks are rectangular concrete masonry oldst units either, solid or hollow. The essential ingredients of concrete blocks are cement, aggregate (sand, gravel) and water. Solid and hollow concrete blocks are manufactured in various sizes to meet the requirements of building blocks in cities and towns. They can be produced manually or with the help of machines.

Concrete solid blocks are made from aggregate, cement and sand. These blocks have a solid material, not less than 75% of the total volume of the block calculated from the overall dimensions. Hence, they are heavy in weight. These blocks provide good stability to the structure. So, these blocks are used for a large work of masonry. They are used in the load-bearing walls as well as the non-load bearing walls. Solid blocks are available in large sizes as compared to the conventional bricks. Therefore, less time is required to construct concrete block masonry than brick masonry.
