The invention belongs to the technical field of building materials, and relates to resource utilization of industrial solid wastes, in particular to a method for preparing self-leveling mortar from phosphorus II type anhydrite. Phosphorus II type anhydrite produced by enterprises is used as a raw material, a plasticizer, a surfactant, a water reducing agent, a retarder and a defoaming agent of certain types and dosages are added, sulfate is used as a combined exciting agent to prepare a self-leveling mortar precursor, water is added, and the mixture is fully stirred to obtain the self-leveling mortar. The invention effectively solves the problems of slow hydration and low early strength of the type II anhydrite, provides a feasible method for preparing the self-leveling mortar from the phosphorus type II anhydrite, and is beneficial to promoting the field of phosphogypsum resource utilization and improving the utilization rate of phosphogypsum.
本发明属于建筑材料技术领域，涉及工业固废的资源化利用，具体为一种磷Ⅱ型无水石膏制备自流平砂浆的方法。本发明以企业生产的磷Ⅱ型无水石膏为原料，添加一定种类和用量的塑化剂、表面活性剂、减水剂、缓凝剂、消泡剂，采用硫酸盐作联合激发剂制备自流平砂浆前躯体，加水后经充分搅拌即为自流平砂浆。本发明有效地解决了Ⅱ型无水石膏水化慢、早期强度低的问题，为磷Ⅱ型无水石膏用于制备自流平砂浆提供了一种切实可行的方法，有利于推动磷石膏资源化利用领域及提升磷石膏利用率。
