In the city bl Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods,In the cityaerated block brick, inspection rules, product quality instructions, stacking, 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). In the city. Aerated blocks, also known as aerated bricks, aerated concrete blocks, autoclaved aerated concrete blocks, and aerated concrete blocks 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). . There are six levels of volumetric density: B03, B04, B05, B06, B07, and B0 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, with an appropriate amount of aerating agent and all parties using this standard should explore the possibility of using the latest versions of the following standards. 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 3-4 times that of clay bricks,In the cityAerated block, 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.

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). Problems such as cracks, hollowing, and falling off. 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. details. This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings. 3 Blocks are divided into three levels based on dimensional deviation, appearance quality, and compressive strength: excellent product (A), first-class product (B), qualified product (C). There are six levels of volumetric density: B03, B04, B05, B06, B07,Strategic Opportunities in the Industry' >
There are six levels of volumetric density: B03, B04, B05, B06, B07, and B0 Test conclusion. 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 Advantages of aerated bricks: Concrete is used as the main raw material for aerated bricks, and then air is added inside, which not only 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). In the city. 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. There are seven strength levels: A0, A0,In the city block,, A5, A5, A0, A5, and A This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.
