Blocks are classified according to their compressive strength and volumetric density.　　Marking examples: strength level A, bulk density level B, superiorHeze,　　Silica sand and slag are ground into slurry with water, then powdered lime, gypsum, and foaming agent are added, stirred, and injected into the mold frame　　Marking examples: strength level A, bulk density level B, superiorHajjah,　　There are six levels of volumetric density: B, B, B, B, B, bulk density level B, superior　　There are seven strength levels: A, A, A, A, A, and A

　　 Blocks are classified according to their compressive strength and volumetric density.　　Very small, with very good seismic performance.　　 Blocks are classified according to their compressive strength and volumetric density.Honesty is the foundation,　　 Block product marking: Mark in the order of product name (code ACB), strength level,Hezeblock, bulk density level, specification size, product grade, and standard number.　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, product quality instructions, stacking and transportation of autoclaved aerated concrete blocks.　　There are six levels of volumetric density: B, B, B B, B, and B

　　 Blocks are classified according to their compressive strength and volumetric density.Credit guarantee,　　 The following standards contain provisions that constitute the provisions of this standard by reference in this standard. At the time of publication of this standard, all versions shown are valid. All standards will be revised, and all parties using this standard should explore the possibility of using the latest versions of the following standards.　　The reason why six parts of ordinary concrete have excellent thermal insulation performance. Aeration block is a lightweight and porous material　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Heze,　　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,HezeAerated block, The sound insulation performance is twice that of clay bricks, the impermeability performance is more than twice that of clay bricks,Hezeautoclaved aerated concrete block, 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, moisture content and A　　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, and water absorption of aerated concrete - Mechanical properties of aerated concrete - Test methods for drying shrinkage of aerated concrete - Test methods for frost resistance of aerated concrete ( - Terminology of bricks and blocks Product classification Specifications: The specifications and dimensions of the blocks are shown in Table
