　　 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).　　Marking examples: strength level A bulk density level B, superiorXinhe,　　Over centimeters.　　There are seven strength levels: A, A, A, A, A, A, and AWest-Raleigh,　　There are six levels of volumetric density: B, B,Xinheaerated block brick, B, B, B, and B　　Marking examples: strength level A, bulk density level B, superior　　There are seven strength levels: A, A, A, A,Xinheblock, A, A, and A

　　There are six levels of volumetric density: B, B, B, B, B, and B　　 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,　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching,Xinheautoclaved 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, 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).Welcome calls ,　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B), 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.Quality department,　　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 　　 According to the prescribed standards the thermal conductivity of qualified aerated bricks is generally between . and .W/mK　　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.Xinhe,　　There are six levels of volumetric density: B, B, B B, B, and B　　Marking examples: strength level A, superior　　If the purchasing unit needs other specifications
