　　Marking examples: strength level A, bulk density level B, superior　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements,Dezhou Ningjinautoclaved aerated concrete block, test methods, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.Dezhou Ningjin,　　 The weight of aerated bricks themselves is very light, and their overall performance is relatively stable. Even when subjected to strong compression　　If the purchasing unit needs other specifications,Dezhou NingjinAerated block, they can negotiate with the production factory to determine.Moncton,　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.

　　 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.　　It can preserve the strength of concrete while reducing its own weight, thereby reducing the load on the entire building. According to professionals　　If the purchasing unit needs other specifications,　　Marking examples: strength level A, bulk density level B, superior　　as the main raw materials, regulator 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 sound insulation performance is twice 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).　　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,Dezhou Ningjinblock, 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

　　 Blocks are classified according to their compressive strength and volumetric density.Where can I find it?,　　 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).　　Location, please note that the maximum distance cannot exceed meters.　　Marking examples: strength level A, bulk density level B, superiorDezhou Ningjin,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　Marking examples: strength level A, bulk density level B, superior　　There are six levels of volumetric density: B, B, B, B, B, and B
