Abstract—More than 40 million residential units are needed to house millions of homeless people in India. Blocks are important components in residential buildings. Even though bricks made of soil have been widely used so far, there is very good scope for using blocks made of cement, sand and coarse aggregates because bricks are not available at all places to the desired requirements. A concrete block is primarily used as a building material in the construction of walls. A concrete block is one of several precast concrete products used in construction. Major advantage of concrete blocks is that their strength can be engineered as per requirement, thus making them relatively stronger than masonry with bricks walls by around 15-20%. The market for building block is growing at a rapid rate, especially in the areas where burnt bricks are not easily available or of poor quality. Unfortunately, rigorous scientific studies have not been made on the strength, durability and economy of concrete building blocks. Lightweight concretes can either be lightweight aggregate concrete, foamed concrete or Autoclaved Aerated Concrete (AAC). Such lightweight concrete blocks are often used in mason's house construction, because of their less density and self-weight, it helps for faster construction.
