　　There are seven strength levels: A, A, A, A, A A, and A　　When deformation occurs, due to the inertia force of the aerated brick　　as the main raw materials during vibration, 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).Highly recommended,　　There are seven strength levels: A, A, A A, A, A, and A　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　There are seven strength levels: A, A, A, A, A,Wuchengautoclaved aerated concrete block, and A
