Specification: 600-200-185 Aerator block
Sand aerated block Introduction to Infilled Walls
Sintered perforated brick: clay, shale, coal gangue, fly ash and other solid wastes are used as the primary raw materials, which are mainly used for bearing parts of buildings after roasting. Traditional cement mortar masonry and plastering construction shall be adopted for the construction process.
Concrete sand aerated block: the concrete small hollow block is formed by adding coarse and fine aggregates such as sand and gravel with cement as the cementing material, measuring and batching, adding water and mixing, and vibrating and pressurizing. Traditional cement mortar masonry and plastering construction shall be adopted for the construction process. Advantages: It is convenient to select materials and has mature technology. It uses sand aerated block materials instead of sintered ordinary bricks to save clay and fuel, and improve the heat insulation and sound insulation performance of bricks.
Defect: the self weight of sand aerated block is 1200~1700kg per cubic meter, which is large; High production energy consumption, low construction efficiency and high transportation cost; Conventional cement mortar is used for masonry and plastering. The amount of cement, sand and other materials is large, the construction period is long, and the transportation cost is high; Common quality problems such as hollowing of plastering layer and cracks caused by sedimentation are difficult to control.
Introduction to traditional aerated block infilled wall
Autoclaved aerated concrete blocks : It is made of fly ash, lime, cement, gypsum, slag, etc. as the primary raw materials, with appropriate amount of gas generating agent, regulator, bubble stabilizer, through the process of mixing, pouring, static stop, cutting and high-pressure steam curing.
Features: As a new wall filling material, compared with the traditional hollow brick masonry material, the data component, fire resistance, impermeability, etc. have been greatly improved, and it is a substitute for the traditional wall materials. The construction process uses traditional mortar masonry and plastering construction.
