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. This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings. Xingtai Lincheng Problems such as cracks， hollowing， and falling off. If the purchasing unit needs other specifications， they can negotiate with the production factory to determine. Lisbon This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings. 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， 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， 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). ， becoming an important component of new building materials. 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. Quality risk Blocks are classified according to their compressive strength and volumetric density. Marking examples: strength level A， superior Block product marking: Mark in the order of product name (code ACB) bulk density level B， strength level， bulk density level， specification size product grade， and standard number.
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，Xingtai Lincheng block，Xingtai Linchengaerated block brick， 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. Where can I find it? Block product marking: Mark in the order of product name (code ACB)， strength level， bulk density level， product grade， and standard number. When constructing aerated bricks， it is required that the mortar strength must meet the design requirements. 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). Xingtai Lincheng 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 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，Xingtai LinchengAerated block， The sound insulation performance is twice that of clay bricks， A 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
