This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings. Marking examples: strength level A， superior Yucheng Promoting the application of earth blocks for external wall self insulation， autoclaved sand aerated concrete blocks， and internal partition wall autoclaved sand aerated concrete blocks 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). Antisense 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 Marking examples: strength level A， bulk density level B，Yuchengaerated block brick，Yuchengautoclaved aerated concrete block，Yucheng block， superior
Specification for autoclaved aerated concrete blocksScope This standard specifies the product classification， technical requirements， test methods， inspection rules， product quality instructions， stacking， and transportation of autoclaved aerated concrete blocks. Aerated blocks have been widely used in load-bearing or non load-bearing structures and pipeline insulation in industrial and civil buildings in China 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). investment 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， appearance quality， volumetric density， and compressive strength: excellent product (A)， first-class product (B)， qualified product (C). Quotation sheet There are six levels of volumetric density: B， B， B， B， and B The construction specifications for aerated block wall masonry require that:Air bricks used for wall masonry must have a production date exceeding Marking examples: strength level A bulk density level B， superior Yucheng Blocks are classified according to their compressive strength and volumetric density. There are six levels of volumetric density: B， B， B， B， B， and B There are seven strength levels: A， A， A， A， A， and A
