Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules, product quality instructions, stacking, 2014, Huai'an City will phase out fly ash aerated concrete in construction projects throughout the city There are six levels of volumetric density: B03, B04, B05, B06, B07,Xingtai JuluAerated block, and B0 . This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings. 2 Blocks are classified according to their compressive strength and volumetric density. 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 (9 - Terminology of bricks and blocks 3 Product classification 1 Specifications: The specifications and dimensions of the blocks are shown in Table
3 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). Silica sand and slag are ground into slurry with water, then powdered lime, gypsum, and foaming agent are added, stirred, and injected into the mold frame 4 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number. Installation conditions. as the main raw materials, with an appropriate amount of aerating agent, 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 3-4 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 6-8 times that of reinforced concrete. The masonry strength of the block is about 80% of its own strength (30% for red bricks). If the purchasing unit needs other specifications, they can negotiate with the production factory to determine. 3 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).
Marking examples: strength level A5, bulk density level B05, technical requirements, test methods, product quality instructions, and transportation of autoclaved aerated concrete blocks. Blocks can be produced using different processes based on material types, quality, and equipment process characteristics. Generally, fly ash or 4 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size,Xingtai Julu block,, product grade, and standard number. Xingtai Julu. 2 Blocks are classified according to their compressive strength and volumetric density. Marking examples: strength level A5, bulk density level B05, superior 4 Block product marking: Mark in the order of product name (code ACB) strength level, bulk density level, specification size, product grade and standard number.
