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.　　 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,　　Block. And it is required that each design unit should indicate the strength of the materials in the design documents when selecting them and all parties using this standard should explore the possibility of using the latest versions of the following standards.Giant Deer,【 Conclusion 】 Although there are differences in the production process and performance between autoclaved aerated concrete blocks and autoclaved aerated concrete precision blocks, the superior performance and widespread application of precision blocks have been recognized and loved by many construction engineers and designers. Autoclaved aerated concrete blocks, aerated concrete blocks, aerated blocks, aerated bricks, foam bricks, foam forming, light bricks, steam cured aerated blocks steam cured aerated bricks, etc. are all the same. It&#;s just that different regions have different understandings and titles. Autoclaved aerated concrete blocks are a type of porous concrete block made from fly ash lime, cement, gypsum, slag etc.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Tome,　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size product grade, and standard number.　　as the main raw materials, with an appropriate amount of aerating agent, 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 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).　　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.

　　Marking examples: strength level A, bulk density level B,Giant Deerblock, superior　　After standing still, foaming, and curing, cut into pieces. Aerated concrete block products are a type of adhesive containing silicon, calcium, sulfur, aluminum, etc　　as the main raw materials, with an appropriate amount of aerating agent, regulator, and processed through batching, 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).Manufacturing cost,　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　Marking examples: strength level A, bulk density level B, superior　　 Blocks are classified according to their compressive strength and volumetric density.

　　There are seven strength levels: A, A, A, A, A, A, and AEquipment maintenance,　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching,Giant DeerAerated 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,Giant Deeraerated block brick, 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).　　Aerated blocks have been widely used in load-bearing or non load-bearing structures and pipeline insulation in industrial and civil buildings in China　　 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).Giant Deer,　　 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.　　There are seven strength levels: A, A, A, A, A, A, and A　　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
