SAND-FREE DESULFURIZATION GYPSUM SELF-LEVELING MORTAR AND PREPARATION METHOD THEREOF
The present disclosure relates to a sand-free desulfurization gypsum self-leveling mortar, comprising the following components in parts by weight: 450-500 parts of gypsum powder, 20-80 parts of cement, 20-70 parts of coal ash, 20-80 parts of ore powder, 5-9 parts of rubber powder, 2-6 parts of defoaming agent, 0.5-1.5 parts of gypsum retarder, 0.5-1.5 parts of water reducing agent and 200-260 parts of water. In the mortar of the present disclosure, flue gas desulfurization gypsum is used to replace natural gypsum, so energy consumption is relatively low, and the utilization rate of desulfurization gypsum is improved; meanwhile, natural sands do not need to be added, so as to avoid environmental destruction caused by overuse of sands. The sand-free desulfurization gypsum self-leveling mortar is high in strength and good in fluidity, the strength, coagulation time and fluidity of the mortar meet the requirements of JCT1023-2007 gypsum-based self-leveling mortar, has the characteristics of stable quality, simple construction and the like, meets industrial policy on national energy conservation, emission reduction and environmental friendliness, and is beneficial to popularization.
