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).　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching,Jinan Overpassautoclaved aerated concrete block, 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,Jinan Overpassblock, 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).Jinan Overpass,　　 days, so that the strength can reach the standard. At the same time, it is required that the brick body should not have cracks and the surface should be clean,　　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.Mozambique,　　Marking examples: strength level A bulk density level B, superior　　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.

　　If the purchasing unit needs other specifications they can negotiate with the production factory to determine.　　Aerated blocks, also known as aerated bricks, aerated blocks, aerated concrete blocks, autoclaved aerated concrete blocks, and aerated concrete blocks　　There are six levels of volumetric density: B, B, B, B, and Bmanagement,　　Marking examples: strength level A, bulk density level B, superior　　There are seven strength levels: A, A, A, A, A, A and A　　 Block product marking: Mark in the order of product name (code ACB), bulk density level, specification size, product grade, and standard number.

　　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,　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules, stacking, and transportation of autoclaved aerated concrete blocks.　　Problems such as cracks, hollowing, and falling off.　　There are six levels of volumetric density: B B, B, B, B, and BJinan Overpass,　　as the main raw materials, with an appropriate amount of aerating agent, regulator, 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, 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.
