Properties of Aerated (Foamed) Concrete Blocks

blocks, concrete industry has seen a small but significant growth in usage of Aerated (foamed) concrete blocks. Simul-taneously, there has been a very significant change in the re-placement of burnt clay bricks by concrete masonry units. It appears that the usage of Aerated concrete block masonry may become more common in the coming years.
