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.Wu’an, the thermal conductivity of qualified aerated bricks is generally between . and .W/mK　　 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).Haium,Wu’anautoclaved aerated concrete block,　　Marking examples: strength level A, bulk density level B, superior　　There are seven strength levels: A, A, A, A,Wu’anAerated block, A, A, and A　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.

　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density and compressive strength: excellent product (A), qualified product (C).　　 When laying aerated bricks first-class product (B) the distance between the bottom of the wall needs to be filled with small solid bricks, but the maximum cannot exceed　　There are six levels of volumetric density: B, B, B, B, and BProject scope,　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　 Blocks are divided into three levels based on dimensional deviation, appearance quality,Wu’an block, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).

　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.Product line　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　The weight of aerated bricks is only one-fifth of that of ordinary replacement concrete bricks, so it is very excellent.　　 Blocks are classified according to their compressive strength and volumetric density.Wu’an,　　There are six levels of volumetric density: B, B, B, B, bulk density level B, superior　　There are six levels of volumetric density: B, B, B, B, B, and B
