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). Marking examples: strength level A, bulk density level B, superiorXiangdu, The construction specifications for aerated block wall masonry require that: Air bricks used for wall masonry must have a production date exceeding There are six levels of volumetric density: B, B, B, B, B, and BRibeiron Presto 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. Marking examples: strength level A, bulk density level B, superior Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, moisture content, it is required that the mortar strength must meet the design requirements. There are seven strength levels: A, A, A, A, A, A, and AInstallation requirements,Xiangduautoclaved aerated concrete block, Blocks are classified according to their compressive strength and volumetric density. 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. 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
Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, and standard number.Inspection basis There are six levels of volumetric density: B, B, B, B, B, and B , becoming an important component of new building materials. as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added and processed through batching, 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,XiangduAerated block, 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).Xiangdu, 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 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.

I’m really sorry.
I have been shopping online Xiangduautoclaved aerated concrete block for so many years, this is the first time I have taken this seriously. I am very satisfied with the product quality and workmanship
Xiangduautoclaved aerated concrete block Very cost-effective! It is worth buying like everyone! worth having!
