　　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.　　There are six levels of volumetric density: B,Tai’an Ningyang block, B, B, B, B and BTai’an Ningyang,　　Starting from January , , Huai&#;an City will phase out fly ash aerated concrete in construction projects throughout the city　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules, stacking, and transportation of autoclaved aerated concrete blocks.Sefrou,　　 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).　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.

　　 Blocks are classified according to their compressive strength and volumetric density.　　Advantages of aerated bricks: Concrete is used as the main raw material for aerated bricks, and then air is added inside, which not only　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density,Tai’an NingyangAerated block, and compressive strength: excellent product (A) first-class product (B), qualified product (C).safety requirements ,　　Marking examples: strength level A, bulk density level B, superior　　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. 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).　　Marking examples: strength level A, bulk density level B, superior

　　If the purchasing unit needs other specifications,Tai’an Ningyangaerated block brick, they can negotiate with the production factory to determine.Service first,　　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. The unit volume weight of autoclaved aerated concrete blocks is one-third of 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).　　Due to its high water absorption rate and drying shrinkage rate, concrete blocks are prone to wall problems after use in construction projects　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A), qualified product (C).Tai’an Ningyang,　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade and standard number.　　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 　　 Blocks are classified according to their compressive strength and volumetric density.
