　　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.Xingtai Shahe,　　Silica sand and slag are ground into slurry with water, then powdered lime, gypsum, and foaming agent are added, stirred, and injected into the mold frame　　Marking examples: strength level A, bulk density level B, superiorJizzax,　　 Blocks are classified according to their compressive strength and volumetric density.　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B), with an appropriate amount of aerating agent,Xingtai Shaheaerated block brick, 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).

　　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 weight of aerated bricks themselves is very light, and their overall performance is relatively stable. Even when subjected to strong compression　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B),　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level specification size, product grade, inspection rules test methods technical requirements, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.

And it is required that each design unit should indicate the strength of the materials in the design documents when selecting them,【 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, foam bricks, foam forming, light bricks, steam cured aerated blocks, 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,Xingtai ShaheAerated block, gypsum, slag, etc.　　There are seven strength levels: A A, A, A, A, A, and AXingtai Shahe,　　Marking examples: strength level A, bulk density level B, superior　　Marking examples: strength level A, bulk density level B, superior　　Marking examples: strength level A, bulk density level B, superior
