Abstract
In the history of building construction brick is one of the oldest of all material. Bricks are very widely use building material because cost of bricks is very cheap and manufacturing of bricks is very simple. Generally, we use bricks in partition wall and main wall of building. strength of brick is satisfactory for building construction. Brick masonry is an easy masonry technique as compare to stone masonry technique but we required more new technology in construction work. Brick masonry and stone masonry take more time in construction of wall and other components of building. So, we required new masonry technique for building construction. In now days most of countries use AAC Blocks instead of bricks. Autoclaved Aerated Concrete block is a light weight concrete block and weight of AAC block is 1/5 of concrete block so dead load of wall and other components is obviously decrease. AAC block have more air bags so weight of AAC block is very less as compared to ordinary concrete block. Basic material of AAC block is widely available in nature. these include sand, cement, lime, fly ash, gypsum, aluminium powder and expansion agent. Autoclaved aerated concrete block contains 70% to 80% air and this air content change accordingly strength and density of AAC blocks.in the last decade, construction industry has been conducting various researches on the utilization of easily available raw materials in construction. AAC blocks are very good material for construction site because AAC blocks are energy efficient and environmentally friendly concrete. This paper introduces with the Autoclaved aerated concrete blocks and its advantages compared to other building materials
