　　 Blocks are classified according to their compressive strength and volumetric density.　　 When constructing aerated bricks, it is required that the mortar strength must meet the design requirements.　　There are seven strength levels: A, A, A, A, A, and ATrustworthy,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　as the main raw materials, regulator, bubble stabilizer added, and processed through batching, mixing, pouring, static stopping, cutting,Lichengaerated block brick, 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).
