　　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.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.Xingtai Guangzong,　　Problems such as cracks, hollowing, and falling off.　　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 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 Burgas,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　 Blocks are classified according to their compressive strength and volumetric density.　　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,Xingtai Guangzong block, The sound insulation performance is 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).

　　 Block product marking: Mark in the order of product name (code ACB),Xingtai Guangzongaerated block brick, strength level, bulk density level, specification size, appearance quality, volumetric density and compressive strength: excellent product (A), first-class product (B), qualified product (C).Finance Department,　　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 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).　　Marking examples: strength level A, bulk density level B, strength level, bulk density level, specification size, product grade, and standard number.

　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Professional is king,　　 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).　　Due to its high water absorption rate and drying shrinkage rate, concrete blocks are prone to wall problems after use in construction projects　　 Block product marking: Mark in the order of product name (code ACB), bulk density level, specification size, product grade, and standard number.Xingtai Guangzong,　　There are seven strength levels: A, A, A, A, A, A,Xingtai GuangzongAerated block, and A　　 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).　　 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).
