Gypsum fly ash aerated concrete block aerated concrete block in Longhua, is made gas process modifiers. Regulation of gypsum is mainly reflected in the lime slurry digestion and thickening rate of delay. The main chemical composition of gypsum is CaSO4. Plaster on the market, there are three: gypsum, anhydrite and plaster. Also Fukuda aerated concrete block, in the chemical production process also produces waste gypsum. As the discharge of phosphogypsum phosphate fertilizer production, chemical production and discharge of fluorine fluorine gypsum, titanium dioxide production of titanium dioxide discharged gypsum and so on. These plaster low cost, can replace natural gypsum, reduce production costs. Typical fly ash aerated concrete block formula and consumption of raw materials: ash: content ratio of 70%; per cubic meter consumption: 350kg; Cement: content ratio of 13.8%; per cubic meter consumption: 25-30kg; lime: content ratio of 13.8%; per cubic meter consumption: 140-150kg; phosphogypsum: content ratio of 2.96%; per cubic meter of consumption: 15kg; aluminum: content trace; per cubic meter consumption: 0.4kg.
