Autoclaved aerated concrete blocks weigh 500-700kg/m3, which is 1/4-1/5 of clay bricks and 1/5 of most concrete. This is a lighter type of concrete. Compared with most brick-concrete structures, the self-weight is reduced by more than 40%.
AAC blocks have very low thermal conductivity, and the thermal insulation effect is 6 times that of clay and 12 times that of ordinary concrete. A 200MM thick block used for external walls can meet the strict requirements of heat preservation and energy saving without auxiliary insulation materials.
The sound insulation volume of the wall built by aac blocks can reach 30-50 decibels. The wall has the dual effect of sound insulation and sound absorption.
The autoclaved aerated concrete block is formed by foaming, and the internal pores are independent and closed, with a uniform size and diameter of about 1MM, which can effectively block water diffusion. And due to the use of mortar masonry, the thickness of the ash joint between the products is not more than 5MM, further improving the overall anti-seepage performance of the wall.
The autoclaved aerated concrete block itself is an inorganic material, a non-combustible material, and has excellent fire performance. The experiment proves that autoclaved gas block product is an ideal fireproof material, and the fire resistance limit of 10CM wall can reach more than 4 hours, which is widely used as a firewall.
As the AAC blocks are generally used for wall structure, the dimension accuracy is essential. The accuracy can reduce the trimming of construction and save motar and other finishing materials.
