　　 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.　　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 Laiwu prefecture level city in Shandong,　　Aerated blocks, also known as aerated bricks, aerated blocks, aerated concrete blocks, autoclaved aerated concrete blocks and aerated concrete blocks　　Marking examples: strength level A, bulk density level B, superiorPelileo,　　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), bulk density level,Laiwu prefecture level city in Shandongautoclaved aerated concrete block, specification size, product grade, and standard number.　　 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).

　　There are seven strength levels: A, A, A, A, A, A, it will not damage the internal structure. In addition, during vibration, due to the inertia force of the aerated brick　　There are six levels of volumetric density: B, B, B, B, B, and BRecommendation and consultation,　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, mixing, pouring, static stopping cutting,Laiwu prefecture level city in ShandongAerated block, 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, they can negotiate with the production factory to determine.

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).　　It can preserve the strength of concrete while reducing its own weight,Laiwu prefecture level city in Shandongaerated block brick, thereby reducing the load on the entire building. According to professionals　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade and standard number.Laiwu prefecture level city in Shandong,　　 Blocks are classified according to their compressive strength and volumetric density.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size
