Gypsum leveling mortar special for building floor
The invention relates to the technical field of building materials, and particularly discloses special gypsum leveling mortar for a building floor. The invention relates to special gypsum leveling mortar for building floors. The leveling mortar is prepared from the following raw materials in parts by weight: 40 to 60 parts of beta semi-hydrated gypsum, 2 to 10 parts of cement, 30 to 40 parts of yellow sand, 5 to 15 parts of glass beads, 0.1 to 1 part of calcium oxide, 0.05 to 0.15 part of tartaric acid and 0.05 to 0.15 part of citric acid. Calcium oxide, tartaric acid and citric acid react to generate insoluble substances, and the insoluble substances cover the surfaces of gypsum crystals in beta semi-hydrated gypsum, so that the growth of gypsum crystal nucleuses is retarded, the hydration speed of the semi-hydrated gypsum is reduced, the coagulation time of the semi-hydrated gypsum in the mortar is delayed, and the construction time is convenient to control. In addition, the mortar has the performance similar to that of gypsum self-leveling, leveling is easy, meanwhile, due to the fact that the mortar is doped with the heat preservation particles, the heat conductivity coefficient is low, and the heat preservation performance is better than that of conventional gypsum self-leveling.
本申请涉及建筑材料的技术领域，具体公开了一种楼地面专用石膏找平砂浆。一种楼地面专用石膏找平砂浆，所述找平砂浆的原料包括如下重量份的组分：β半水石膏40~60份、水泥2~10份、黄砂30~40份、玻化微珠5~15份、氧化钙0.1~1份、酒石酸0.05~0.15份、柠檬酸0.05~0.15份。本申请中氧化钙、酒石酸、柠檬酸反应生成难溶物，难溶物覆盖在β半水石膏中石膏晶体的表面，从而阻滞了石膏晶核的生长，降低了半水石膏的水化速度，从而延缓了砂浆中半水石膏的凝结时间，方便控制施工时间。另外本申请中的砂浆有类似石膏自流平的性能，易找平，同时，该砂浆因为掺入了保温颗粒，所以导热系数低，保温性能比常规石膏自流平要好。
