Autoclaved Aerated concrete (AAC) have a lot of profit used for structure such as heat insulation, sound insulation, fire as well as mould confrontation, abridged dead load as well as a lot more. AAC products take in block, wall panel, ground also top panels, also lintels. as well insulate ability, one of AAC's compensation in creation is its fast with simple setting up while the material can be routed, sand also slice to dimension on site by normal carbon steel band saws, hand saws also drills. Although ACC is being created for a lot of years, here are still a little point so as to need to be clarify. One of these points is humidity intrusion effects on AAC members in areas with high relative humidity levels of Mediterranean climates which are important in durability and insulation properties of AAC. This work presents the identify the usage of AAC in construction projects. This work also provides the economical comparative analysis with clay bricks as well as AAC blocks, and how AAC block is effective that clay bricks. This work also can improve the sound insulation of internal and external wall. The experimental analysis shows the test results of proposed system with internal as well as external walls.
