If the purchasing unit needs other specifications， they can negotiate with the production factory to determine. There are seven strength levels: A， A， A，Wucheng, Texasautoclaved aerated concrete block， A， A， A， and A Wucheng，Wucheng, Texasaerated block brick， Texas When constructing aerated bricks， it is required that the mortar strength must meet the design requirements. 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， appearance quality volumetric density， and compressive strength: excellent product (A)， first-class product (B)， qualified product (C). 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).
There are six levels of volumetric density: B， B， B， B， B，Wucheng, TexasAerated block， and B Problems such as cracks， hollowing， and falling off. There are seven strength levels: A， A， A， A， A， and A Sincere service 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). Specification for autoclaved aerated concrete blocksScope This standard specifies the product classification， technical requirements， test methods， product quality instructions， stacking， and transportation of autoclaved aerated concrete blocks. 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. Installation materials 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. The weight of aerated bricks is only one-fifth of that of ordinary replacement concrete bricks， so it is very excellent. There are six levels of volumetric density: B， B， B， B， B， Texas 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， 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). 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
