Marking examples: strength level A, bulk density level B,Handan GuangpingAerated block, superior　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.Handan Guangping,　　 According to the prescribed standards, the thermal conductivity of qualified aerated bricks is generally between . and .W/mK　　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,Handan Guangpingaerated block brick, 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).Udon Thani,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　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.

　　 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).　　The weight of aerated bricks is only one-fifth of that of ordinary replacement concrete bricks, so it is very excellent.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Trustworthy,　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　There are seven strength levels: A, A, A, A, A, A, and A　　 Blocks are classified according to their compressive strength and volumetric density.

　　There are seven strength levels: A, A, A, A, A, and AWelcome calls ,　　There are six levels of volumetric density: B, B B, B, B, and B　　After standing still, foaming, and curing, cut into pieces. Aerated concrete block products are a type of adhesive containing silicon, calcium, sulfur, aluminum, etc　　 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.Handan Guangping, moisture content, bulk density level strength level, product grade, and standard number.　　 Blocks are divided into three levels based on dimensional deviation, appearance quality,Handan Guangpingblock, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).
