Many new inventions are out of necessity. 6 Hole bricks are a good construction material. Modern constructions are mostly column-beam structures . The weight of the building rest on the beams and columns. As far as the technical view is concerned, hollow bricks are light,durable, easily available and gives adequate strength to the construction. It reduces the induced heat inside the building due to the hollow portion inside,making the building cooler. 6 Hole bricks are made with clay which are stronger but little costly and not readily available. Hollow bricks add to the architectural aesthetics and gives a better view as compared to solid brick.
