LongyaoAerated block,

　　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,　　Aerated blocks have been widely used in load-bearing or non load-bearing structures and pipeline insulation in industrial and civil buildings in China　　 Blocks are classified according to their compressive strength and volumetric density.Esenyurt,　　 Block product marking: Mark in the order of product name (code ACB), bulk density level specification size, product grade and standard number.　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules, stacking 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

　　 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).　　When deformation occurs, it will not damage the internal structure. In addition, during vibration, due to the inertia force of the aerated brick　　 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).Good quality,　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A),Longyaoautoclaved aerated concrete block, first-class product (B), qualified product (C).　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　There are seven strength levels: A, A, A, A, A, A, and A

　　Marking examples: strength level A, bulk density level B, superiorAnalysis project,　　There are seven strength levels: A, A, A, A, A, A,Longyaoblock, 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　　 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, and all parties using this standard should explore the possibility of using the latest versions of the following standards.Longyao,　　There are seven strength levels: A, A, A, A, A, A, and A　　 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 classified according to their compressive strength and volumetric density.
