CONCRETE BLOCKS are usually made in large sizes to make blockwork faster and consume less cement in joints than the brickwork. If the percentage of the voids is more than 25%, then they are hollow blocks and blocks with voids less than 25% are only perforated blocks.
The cellular concrete blocks are generally referred to as lightweight aerated concrete blocks. All these blocks are extensively used for compound walls and non-loadbearing walls.
Hollow blocks are specially made for loadbearing walls, which are useful in reducing a dead load of masonry in buildings. Blocks can also be with cement and sand called cement-sand blocks or with cement and soil called soil-cement blocks which are of low strength and use for low-cost construction.
Concrete blocks are nowadays replacing bricks in masonry construction, notably in many multi-storeyed buildings. They are available in three types namely solid, hollow and cellular, widely used for the construction of filler walls and boundary walls in RC framework.
