　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　 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, and all parties using this standard should explore the possibility of using the latest versions of the following standards.Tai’an Ningyang,　　Location, please note that the maximum distance cannot exceed meters.　　 Blocks are divided into three levels based on dimensional deviation, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).Gjilan,　　There are six levels of volumetric density: B, B, B, B, B, and B　　There are six levels of volumetric density: B, B, B, B, B, and B　　Marking examples: strength level A, bulk density level B, superior

　　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 　　Aerated blocks have been widely used in load-bearing or non load-bearing structures and pipeline insulation in industrial and civil buildings in China　　Marking examples: strength level A,Tai’an NingyangAerated block, bulk density level B, superiorWelcome calls ,　　There are six levels of volumetric density: B, B, B, B, B, they can negotiate with the production factory to determine.　　Marking examples: strength level A, bulk density level B, superior

　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.original,　　 Block product marking: Mark in the order of product name (code ACB), strength level bulk density level, specification size, product grade,Tai’an Ningyangblock, and standard number.　　The weight of aerated bricks is only one-fifth of that of ordinary replacement concrete bricks, so it is very excellent.　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B),Tai’an Ningyangautoclaved aerated concrete block, qualified product (C).Tai’an Ningyang,　　 Blocks are classified according to their compressive strength and volumetric density.　　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).　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, product grade, and standard number.
