Xingtai Xindu block,

　　If the purchasing unit needs other specifications, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).Xingtai Xindu,　　Silica sand and slag are ground into slurry with water then powdered lime, gypsum, and foaming agent are added, stirred, and injected into the mold frame　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade,Xingtai XinduAerated block, and standard number.Dallas,　　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, strength level 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).　　 Block product marking: Mark in the order of product name (code ACB), bulk density level,Xingtai Xinduaerated block brick, specification size, product grade, and standard number.　　 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.
