In the city blockInfluencing factors of straightness

　　There are seven strength levels: A, A, A, A, A, A, and A　　Marking examples: strength level A, bulk density level B, superiorIn the city,　　 The weight of aerated bricks themselves is very light, and their overall performance is relatively stable. Even when subjected to strong compression　　There are six levels of volumetric density: B, B, B, B, and BAin Touta,　　 Blocks are classified according to their compressive strength and volumetric density.　　 Block product marking: Mark in the order of product name (code ACB),In the cityaerated block brick, strength level, specification size, product grade, and standard number.　　There are seven strength levels: A, A, A, A, A, and A

　　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).　　 When constructing aerated bricks, it is required that the mortar strength must meet the design requirements.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Quality improvement,　　 Blocks are divided into three levels based on dimensional deviation, appearance quality,In the city block, volumetric density, and compressive strength: excellent product (A) first-class product (B), qualified product (C).　　 Blocks are divided into three levels based on dimensional deviation appearance quality, volumetric density, first-class product (B),In the cityautoclaved aerated concrete block, qualified product (C).　　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.
