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.Longyao,　　Due to its high water absorption rate and drying shrinkage rate, concrete blocks are prone to wall problems after use in construction projects　　 Blocks are classified according to their compressive strength and volumetric density.Sumgate,　　 Blocks are classified according to their compressive strength and volumetric density.　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, stacking, and transportation of autoclaved aerated concrete blocks.　　Marking examples: strength level A, bulk density level B, superior

　　 Blocks are classified according to their compressive strength and volumetric density.　　When deformation occurs, it will not damage the internal structure. In addition,Longyaoaerated block brick, during vibration, due to the inertia force of the aerated brick　　 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.Welcome calls ,　　 Blocks are divided into three levels based on dimensional deviation,LongyaoAerated block, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B),Longyaoautoclaved aerated concrete block, qualified product (C).　　There are seven strength levels: A, A, A, A, A, A, and A　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.

　　 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).production,　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　 When laying aerated bricks, the distance between the bottom of the wall needs to be filled with small solid bricks, but the maximum cannot exceed　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.Longyao,　　There are six levels of volumetric density: B, B, B, B, B, and B　　There are seven strength levels: A, A, A, and A　　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 A 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
