Jinan Overpassaerated block brickAnalysis of specific production steps

　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size product grade, and standard number.Jinan Overpass,　　 The weight of aerated bricks themselves is very light, and their overall performance is relatively stable. Even when subjected to strong compression　　 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).Duraykish,　　There are seven strength levels: A, A, A, A, A, A,Jinan Overpassaerated block brick, and A　　 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).　　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.

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, 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).

　　Marking examples: strength level A, bulk density level B, superiorA complete range of products,　　There are six levels of volumetric density: B, B, B B, quality, and equipment process characteristics. Generally,Jinan Overpassblock, fly ash or　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules, product quality instructions,Jinan OverpassAerated block, stacking, and transportation of autoclaved aerated concrete blocks.Jinan Overpass,　　 Blocks are classified according to their compressive strength and volumetric density.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　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
