　　 Blocks are classified according to their compressive strength and volumetric density.　　 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,　　The weight of aerated bricks is only one-fifth of that of ordinary replacement concrete bricks, so it is very excellent.　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements,Feixiangblock,FeixiangAerated block, test methods, inspection rules,Feixiangaerated block brick, product quality instructions stacking, and transportation of autoclaved aerated concrete blocks.Uruguay,　　 Blocks are classified according to their compressive strength and volumetric density.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　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

　　 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.　　 The weight of aerated bricks themselves is very light, and their overall performance is relatively stable. Even when subjected to strong compression　　 Blocks are classified according to their compressive strength and volumetric density.Installation material list,　　There are seven strength levels: A, A, A, A, A, A, and A　　There are seven strength levels: A, A, A, A, A, and A　　There are six levels of volumetric density: B, B, B, B, B, and B

　　 Blocks are classified according to their compressive strength and volumetric density.Quality assurance,　　 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).　　It can preserve the strength of concrete while reducing its own weight, thereby reducing the load on the entire building. According to professionals　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Feixiang,　　There are six levels of volumetric density: B, B B, B, and B　　There are seven strength levels: A, A, A, A, A, A, and A　　Marking examples: strength level A, bulk density level B, superior
