Abstract

The invention belongs to the technical field of building materials, and discloses an aerated brick preparation method, which comprises: 1, grinding: putting raw materials of fly ash, quick lime, diatomite, cement, aluminum powder and gypsum into a grinder, grinding, adding into a stirrer, adding water, and sufficiently stirring to obtain a mixture; 2, additive adding: adding 0.3-0.4 part of sodiumchloride and 0.5-0.7 part of a fluorine surfactant into the stirrer, and fully stirring; 3, heating: pouring the mixture into a mold, carrying out extrusion molding, transferring into a drying room,and drying for 1-3 h at a temperature of 40-45 DEG C to prepare a rough brick; and 4, steam curing: putting the rough brick into an autoclave, and carrying out steam curing for 6-18 h at a temperatureof 180-250 DEG C under a pressure of 8-10 Mpa to finally obtain the aerated brick. According to the invention, through the synergistic effect of the sodium chloride and the fluorine surfactant, the purposes of sterilization and corrosion prevention of the aerated brick are achieved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a method for preparing an aerated brick. Background technique [0002] Aerated bricks, also known as autoclaved aerated concrete blocks, are made of fly ash, lime, cement, gypsum, slag, etc. A concrete product made by processes such as static stopping, cutting and autoclaving. Aerated bricks are widely used as a light-weight thermal insulation new building wall material, mainly in mechanical workshops and civil buildings. As the country banned the production of clay solid bricks, aerated bricks have become the leading product in the building materials industry. [0003] The biggest advantage of aerated bricks is to save land resources, without wasting a lot of cultivated land, and its source of raw materials is very extensive, and the performance characteristics of aerated bricks are very superior, with good heat insulation and heat preservation capabilities, and str...
