Tai’an blockQuality classification

　　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 　　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,　　Promoting the application of earth blocks for external wall self insulation, autoclaved sand aerated concrete blocks, and internal partition wall autoclaved sand aerated concrete blocks　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.Soyapango, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).　　Marking examples: strength level A, bulk density level B, superior　　There are seven strength levels: A, A, A,Tai’an block, A, A, A, and A

　　There are six levels of volumetric density: B, B, B, B, B, and B　　 When laying aerated bricks it is necessary to make batches of poles according to the height of the bricks, and then erect them at the corners of the wall　　 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.Safety and health,　　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.　　 Block product marking: Mark in the order of product name (code ACB),Tai’anAerated block, strength level, bulk density level, specification size, product grade, and standard number.　　 Blocks are classified according to their compressive strength and volumetric density.

　　There are seven strength levels: A, A, A, A, A, and AWord of mouth recommendation,　　 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.　　Promoting the application of earth blocks for external wall self insulation, autoclaved sand aerated concrete blocks, and internal partition wall autoclaved sand aerated concrete blocks　　 Blocks are classified according to their compressive strength and volumetric density.Tai’an,Tai’anaerated block brick,　　 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).　　 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.　　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.
