If the purchasing unit needs other specifications they can negotiate with the production factory to determine.　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.In the city,　　When deformation occurs, it will not damage the internal structure. In addition, during vibration, due to the inertia force of the aerated brick　　 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,In the cityautoclaved aerated concrete block, and all parties using this standard should explore the possibility of using the latest versions of the following standards.Edessa,　　If the purchasing unit needs other specifications,In the cityaerated block brick, they can negotiate with the production factory to determine.　　 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 ( - Terminology of bricks and blocks Product classification Specifications: The specifications and dimensions of the blocks are shown in Table

　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　 When laying aerated bricks the distance between the bottom of the wall needs to be filled with small solid bricks, but the maximum cannot exceed　　 Block product marking: Mark in the order of product name (code ACB), bulk density level, specification size, product grade, and standard number.management,　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching, mixing, pouring, static stopping, 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).　　as the main raw materials, with an appropriate amount of aerating agent regulator,In the cityblock, bubble stabilizer added, and processed through batching, mixing, pouring, static stopping, cutting, and high-pressure steam curing.
