Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　 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).Dezhou Qihe　　When deformation occurs, it will not damage the internal structure. In addition,Dezhou Qihe block, during vibration, due to the inertia force of the aerated brick　　There are six levels of volumetric density: B, B, B, B, and BDara,　　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 six levels of volumetric density: B, B, B, B, B, and B　　as the main raw materials,Dezhou QiheAerated block, with an appropriate amount of aerating agent, 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 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).

　　There are seven strength levels: A, A, A A, A, A, and A　　Promoting the application of earth blocks for external wall self insulation, autoclaved sand aerated concrete blocks, and internal partition wall autoclaved sand aerated concrete blocks　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Quality assurance,　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, test methods, inspection rules, product quality instructions stacking, moisture content and transportation of autoclaved aerated concrete blocks.　　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, 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 　　There are seven strength levels: A, A, A, A,Dezhou Qiheaerated block brick, A, A, and A

　　 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.market,　　 Blocks are classified according to their compressive strength and volumetric density.　　Starting from January , , Huai&#;an City will phase out fly ash aerated concrete in construction projects throughout the city　　 Blocks are classified according to their compressive strength and volumetric density.Dezhou Qihe,　　Marking examples: strength level A, bulk density level B, superior　　There are seven strength levels: A, A, A, A, A, A, and A　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.
