<b>Beneficial Usage of Autoclaved Aerated Concrete Block</b> This paper is about the study of beneficial usage of AAC block production in Mother Industrial Co., Ltd AAC and APC block factory . Autoclaved Aerated Concrete is one of such green materials. It not only uses the waste material like fly ash but also provides adequate strength to structures. The main aim of this paper is to show the beneficial usage of AAC block instead of the use of conventional brick. For that, the beneficial usage of AAC block is showed on many ways. The beneficial usage of AAC block shows the cost saving calculation of AAC block. As the next way, the beneficial usage of AAC block shows the weight saving calculation of AAC block. Quality control chart x bar and R chart use to prove the benefit of AAC blocks in checking the production process. The other way is the compressive strength calculation between conventional brick and AAC block to show the benefit of AAC block. Finally, the power consumption cost saving calculation of AAC block compared with conventional brick is to show the benefit of AAC block. aerated concrete block, beneficial usage, cost saving, compressive strength, weight saving, power consumption cost 1961-1965 Issue-5 Volume-2 Khin War Oo | Su Nandar Hlaing
