Liaocheng Dongchang PrefectureAerated blockHow to protect the system

　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　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 Liaocheng Dongchang Prefecture,　　Advantages of aerated bricks: Concrete is used as the main raw material for aerated bricks, and then air is added inside, which not only　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.Esperanza,　　There are seven strength levels: A, A, A, A, A, and A　　 Blocks are classified according to their compressive strength and volumetric density.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.

　　 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, and all parties using this standard should explore the possibility of using the latest versions of the following standards.　　Starting from January , , Huai&#;an City will phase out fly ash aerated concrete in construction projects throughout the city　　 Blocks are classified according to their compressive strength and volumetric density.Production department,　　There are seven strength levels: A, A, A, A, A, A, and A　　 Blocks are divided into three levels based on dimensional deviation appearance quality,Liaocheng Dongchang Prefectureblock, volumetric density, and compressive strength: excellent product (A), first-class product (B) qualified product (C).　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules, product quality instructions, stacking, with an appropriate amount of aerating agent,Liaocheng Dongchang PrefectureAerated block, regulator, bubble stabilizer added, and processed through batching,Liaocheng Dongchang Prefectureautoclaved aerated concrete block, mixing, pouring, static stopping, cutting, 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).Direct material,　　There are six levels of volumetric density: B, B, B, B, B, and B　　 When constructing aerated bricks, it is required that the mortar strength must meet the design requirements.　　Marking examples: strength level A, bulk density level B, superiorLiaocheng Dongchang Prefecture　　 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).　　 Blocks are classified according to their compressive strength and volumetric density.　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.
