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.　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.Qiu County, Handan,　　With the advantages of processing, it can be made into wall blocks, insulation blocks,Qiu County, Handanblock, pressure panels, floor slabs, wall panels, and insulation pipes　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.Gambia,　　There are six levels of volumetric density: B, B, B, B, B, and B　　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 　　 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.

　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　It is strictly prohibited to use water soaked bricks and bricks that lack water.　　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.Welcome calls ,　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods inspection rules, product quality instructions,Qiu County, Handanautoclaved aerated concrete block, stacking, and transportation of autoclaved aerated concrete blocks.　　There are seven strength levels: A, A, A, A, A, A, 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

　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Quality improvement,　　 Blocks are classified according to their compressive strength and volumetric density.　　Very small, with very good seismic performance.　　as the main raw materials,Qiu County, HandanAerated block, 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).Qiu County,　　 Block product marking: Mark in the order of product name (code ACB), bulk density level, specification size, product grade, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.
