Sand-free desulfurized gypsum self-leveling mortar and preparation method thereof
The invention relates to sand-free desulfurized gypsum self-leveling mortar which comprises the following components in parts by weight: 450-500 parts of gypsum powder, 20-80 parts of cement, 20-70 parts of fly ash, 20-80 parts of mineral powder, 5-9 parts of rubber powder, 2-6 parts of a defoaming agent, 0.5-1.5 parts of a gypsum retarder, 0.5-1.5 parts of a water reducing agent and 200-260 partsof water. According to the mortar, flue gas desulfurization gypsum is adopted to replace natural gypsum, energy consumption is low, the utilization rate of desulfurization gypsum is increased, meanwhile, natural sand does not need to be added, and the problem of environmental damage caused by excessive use of sand is avoided. The sand-free desulfurized gypsum self-leveling mortar is high in strength and fluidity, the strength, the setting time and the fluidity of the mortar meet the requirements of JCT1023-2007 gypsum-based self-leveling mortar, and the sand-free desulfurized gypsum self-leveling mortar has the characteristics of stable quality, simplicity in construction and the like, conforms to the national industrial policies of energy conservation, emission reduction and environmental protection, and is beneficial to popularization and application.
本发明涉及一种无砂脱硫石膏自流平砂浆，包括如下重量份的组分：石膏粉450‑500份，水泥20‑80份，粉煤灰20‑70份，矿粉20‑80份，胶粉5‑9份，消泡剂2‑6份，石膏缓凝剂0.5‑1.5份，减水剂0.5‑1.5份，水200‑260份。本发明的砂浆采用烟气脱硫石膏替换天然石膏，能耗比较低，提高了脱硫石膏的利用率，同时不需要加入自然砂，避免了过度使用砂子造成的环境破环问题。该无砂脱硫石膏自流平砂浆强度高，流动性好，该砂浆的强度、凝结时间、流动度满足JCT1023‑2007石膏基自流平砂浆的要求，具有质量稳定、施工简单等特征，符合国家节能、减排、环保的产业政策，有利于推广应用。
