Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A), qualified product (C).Yanggu,　　When deformation occurs, it will not damage the internal structure. In addition during vibration, moisture content due to the inertia force of the aerated brick　　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 Sanbaoyan,　　 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 classified according to their compressive strength and volumetric density.　　as the main raw materials, with an appropriate amount of aerating agent, bubble stabilizer added, and processed through batching, mixing pouring, static stopping, cutting,Yangguautoclaved aerated concrete block, 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, 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 six levels of volumetric density: B, B, B, B, B, and B　　The weight of aerated bricks is only one-fifth of that of ordinary replacement concrete bricks, so it is very excellent.　　 Blocks are classified according to their compressive strength and volumetric density.Customer first,　　 Blocks are classified according to their compressive strength and volumetric density.　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules, product quality instructions,Yanggublock, stacking, and transportation of autoclaved aerated concrete blocks.　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, product grade, and standard number.
