Jinan Overpassaerated block brickHow to solve problems in the industry

　　 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.　　 Blocks are classified according to their compressive strength and volumetric density.Jinan Overpass,　　The weight of aerated bricks is only one-fifth of that of ordinary replacement concrete bricks, so it is very excellent.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Halmstad,　　There are seven strength levels: A, A A, A A,Jinan Overpassblock, A,Jinan Overpassaerated block brick, and A　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching, mixing, pouring, 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).　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.

　　There are six levels of volumetric density: B, B, B, B, B, and B　　Over centimeters.　　 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,　　There are six levels of volumetric density: B, B, B B, B, and B　　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,Jinan OverpassAerated block, 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 　　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.Executive standard,　　There are seven strength levels: A, A, A, A, A, A, it will not damage the internal structure. In addition, during vibration, due to the inertia force of the aerated brick　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A), qualified product (C).Jinan Overpass,　　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, product grade, and standard number.　　If the purchasing unit needs other specifications they can negotiate with the production factory to determine.
