加气混凝土砌块墙体施工质量控制要点（Construction quality control points of reinforced concrete block wall） Aerated concrete block or river sand is the cement, lime, gypsum and fly ash as the main raw material, with aluminum powder as the gas agent after foaming and forming and autoclaved curing process microporous block made of wall materials. As a load-bearing and non-load-bearing structural material and insulation material, it has the advantages of light weight, good insulation insulation and sound insulation, a certain mechanical strength and machinability. This paper discusses the construction quality control points of reinforced concrete block wall. 1. The crack of material control points is the quality of the reinforced concrete block wall, which is related to the contraction of the reinforced concrete block material itself. Therefore, it is necessary to select the block with small shrinkage value when choosing block. Generally speaking, the higher the density of the material, the lower the drying shrinkage value will be, but at the same time, the requirements of the thermal conductivity of the block should be met. Manufacturers because of the different raw materials and process conditions, the block of drying shrinkage difference is bigger, in order to ensure the quality, should choose mature production technology, maintenance condition good manufacturers products, product quality is stable. When the block is low in strength, it is strictly forbidden to dump and toss the dump truck during transportation and loading and unloading, so as to avoid breakage of the block. Block, adhesives, interface agent, special mortar, galvanized steel wire net, alkali-resistant glass fiber grid cloth and other approach must test the product certification and quality policy, the main properties of the material must have the supervision of witness sampling, do get the re-inspection. In particular, it is required to check whether the storage time of the manufacturer after the block is in accordan
