In the city block,The stress when it continues to elongate

　　3 Blocks are divided into three levels based on dimensional deviation, appearance quality,In the cityautoclaved aerated concrete block,, volumetric density, and compressive strength: excellent product (A),In the cityaerated block brick,In the cityAerated block, first-class product (B), qualified product (C).

　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching mixing, pouring, static stopping, cutting, and high-pressure steam curing. The unit volume weight of autoclaved aerated concrete blocks is one-third of that of clay bricks, 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).

In the city.　　 The weight of aerated bricks themselves is very light, and their overall performance is relatively stable. Even when subjected to strong compression

　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.

.　　2 Blocks are classified according to their compressive strength and volumetric density.

　　4 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade,The stress when it continues to elongate' >

　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.

　　Problems such as cracks, hollowing, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).

　　There are seven strength levels: A0, A5, A5, A0, A5 and A

　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.

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

The cheapest.　　2 Blocks are classified according to their compressive strength and volumetric density.

　　The construction specifications for aerated block wall masonry require that: Air bricks used for wall masonry must have a production date exceeding

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

In the city.　　There are seven strength levels: A0, A0, A5, A5, A0, A5, and A
