There are seven strength levels: A， A A， A， A， A， and A 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. Leling Very small， with very good seismic performance. This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings. Hashi 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. Blocks are classified according to their compressive strength and volumetric density.
There are seven strength levels: A， A， A， A， A， A， and A Over centimeters. 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. knowledge If the purchasing unit needs other specifications， they can negotiate with the production factory to determine. 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，Leling block， 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). There are seven strength levels: A， A， A， A， A， and A
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). analysis Blocks are divided into three levels based on dimensional deviation， appearance quality volumetric density， first-class product (B)， qualified product (C). 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 Marking examples: strength level A， bulk density level B， superior Leling There are seven strength levels: A， A， A， A，Lelingautoclaved aerated concrete block， A， A， and A 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， and the fire resistance performance is - times that of reinforced concrete.
