　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, static stopping pouring, 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).　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Shen County, Liaocheng,　　Starting from January , , Huai&#;an City will phase out fly ash aerated concrete in construction projects throughout the city　　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 More than Saida,　　 Blocks are classified according to their compressive strength and volumetric density.　　If the purchasing unit needs other specifications,Shen County, LiaochengAerated block, they can negotiate with the production factory to determine.　　 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.

　　There are seven strength levels: A, A, A, A, A, and A　　Due to its high water absorption rate and drying shrinkage rate, concrete blocks are prone to wall problems after use in construction projects　　Marking examples: strength level A, bulk density level B,Shen County, Liaochengblock, superiorDesign brand,　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching, mixing, pouring, cutting, and high-pressure steam curing.
