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. Liaocheng Yanggu Advantages of aerated bricks:Concrete is used as the main raw material for aerated bricks, and then air is added inside, which not only There are six levels of volumetric density: B, B, B, B, B, and B Bechem There are six levels of volumetric density: B, B, B, B, B, and B Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size,Liaocheng YangguAerated block, product grade, and standard number. Specification for autoclaved aerated concrete blocksScope This standard specifies the product classification, technical requirements, test methods, inspection rules, product quality instructions, and transportation of autoclaved aerated concrete blocks.
Blocks are divided into three levels based on dimensional deviation appearance quality,Liaocheng Yanggu block, and compressive strength: excellent product (A), first-class product (B), qualified product (C). Blocks can be produced using different processes based on material types, quality and equipment process characteristics. Generally, fly ash or 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. Supply chain quality management 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 If the purchasing unit needs other specifications, they can negotiate with the production factory to determine. There are seven strength levels: A, A, A, A, A, and A
There are seven strength levels: A, A, A, A, A,Liaocheng Yangguaerated block brick, and A Word of mouth recommendation If the purchasing unit needs other specifications, they can negotiate with the production factory to determine. With the advantages of processing, insulation blocks, pressure panels, floor slabs, wall panels, and insulation pipes Block product marking: Mark in the order of product name (code ACB), bulk density level strength level, specification size, product grade, and standard number. Liaocheng Yanggu 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 - 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). 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.
