Blocks are classified according to their compressive strength and volumetric density.　　There are seven strength levels: A, A, A, A, A A, and ALinzhang,　　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　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.Bosaso,　　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 - 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,Linzhangblock, and the fire resistance performance is - times that of reinforced concrete. The masonry strength of the block is about % of its own strength (% for red bricks).　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules, product quality instructions, stacking, strength level, bulk density level, specification size, and standard number.

　　There are six levels of volumetric density: B, B, B, B, B, and B　　Aerated blocks, also known as aerated bricks, aerated blocks, aerated concrete blocks, autoclaved aerated concrete blocks, and aerated concrete blocks　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.how much,　　Control standard for radioactive substances in building materials mixed with industrial waste - Determination of steady-state thermal resistance and related characteristics of insulation materials - Protective hot plate method for testing the performance of aerated concrete - General rules - Test methods for volumetric density, moisture content,Linzhangaerated block brick, bulk density level,LinzhangAerated block, specification size, product grade, and standard number.　　as the main raw materials, with an appropriate amount of aerating agent, 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 - 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 - times that of reinforced concrete. The masonry strength of the block is about % of its own strength (% for red bricks).

　　There are seven strength levels: A, A, A, A, A A, and Adetails,　　 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).　　Condensing materials. As the main raw material. This aerated concrete block has the advantages of insulation, moisture resistance, and lightweight.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Linzhang,　　 Blocks are classified according to their compressive strength and volumetric density.　　Marking examples: strength level A, bulk density level B, superior　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.
