In the city block,What factors affect the service life

In the cityautoclaved aerated concrete block,,

　　3 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).

　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.

In the city.　　Promoting the application of earth blocks for external wall self insulation, autoclaved sand aerated concrete blocks, and internal partition wall autoclaved sand aerated concrete blocks

　　4 Block product marking: Mark in the order of product name (code ACB) strength level, bulk density level, specification size, product grade, and compressive strength: excellent product (A) volumetric density appearance quality, first-class product (B), qualified product (C).

　　There are six levels of volumetric density: B03, B04, B05, B06, B07, and B0

The unit volume weight of autoclaved aerated concrete blocks is one-third of that of clay bricks,In the cityAerated block, and the insulation performance is 3-4 times that of clay bricks, The sound insulation performance is twice that of clay bricks, the impermeability performance is more than twice that of clay bricks, and the fire resistance performance is 6-8 times that of reinforced concrete. The masonry strength of the block is about 80% of its own strength (30% for red bricks).
