　　There are seven strength levels: A, A, A,Wu’an block, A, A, A,Wu’anaerated block brick, and A　　There are six levels of volumetric density: B B, B, B, B, and BWu’an,　　, becoming an important component of new building materials.　　Marking examples: strength level A, bulk density level B, superiorZouila,　　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, test methods, inspection rules, product quality instructions stacking, and transportation of autoclaved aerated concrete blocks.　　Marking examples: strength level A, bulk density level B, superior

　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　Starting from January , , Huai&#;an City will phase out fly ash aerated concrete in construction projects throughout the city　　There are seven strength levels: A, A, A, A, A, and Aassets　　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, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching, mixing, static stopping,Wu’anAerated block, 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 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).　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.

　　 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).Work courses,　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　Condensing materials. As the main raw material. This aerated concrete block has the advantages of insulation, and lightweight.　　 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.Wu’an,　　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.　　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
