　　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 　　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.Jining Rencheng,　　Starting from January , , Huai&#;an City will phase out fly ash aerated concrete in construction projects throughout the city　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added,Jining Renchengautoclaved aerated concrete block, 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).El-Estor,　　as the main raw materials, 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.

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.　　 Blocks are classified according to their compressive strength and volumetric density.

　　There are six levels of volumetric density: B, B, B, B, B, and B　　,　　 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.　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　There are seven strength levels: A, A,Jining Renchengaerated block brick, A, A, A, A, and A

　　There are six levels of volumetric density: B, B, B, B, and BHow much is it,　　There are six levels of volumetric density: B,Jining Renchengblock, B, B, B, and B　　The weight of aerated bricks is only one-fifth of that of ordinary replacement concrete bricks, so it is very excellent.　　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.Jining Rencheng,　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　There are seven strength levels: A, A A, A, A, A, and A　　If the purchasing unit needs other specifications
