Jizeaerated block brick,

　　 Blocks are classified according to their compressive strength and volumetric density.　　 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).Jize,　　 When laying aerated bricks, it is necessary to make batches of poles according to the height of the bricks, and then erect them at the corners of the wall　　 Blocks are classified according to their compressive strength and volumetric density.Silang,　　There are seven strength levels: A A, A, A, A,JizeAerated block, A, and A　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　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 　　 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,　　Marking examples: strength level A, bulk density level B, superior　　There are seven strength levels: A, A, A, A, A, A, and A　　There are six levels of volumetric density: B B, B, B, and B

　　 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).Promise and keep promise,　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods,Jize block, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　It is strictly prohibited to use water soaked bricks and bricks that lack water.　　 Blocks are classified according to their compressive strength and volumetric density.Jize,　　Marking examples: strength level A, bulk density level B, superior　　Marking examples: strength level A, bulk density level B, superior　　Marking examples: strength level A, bulk density level B, superior
