Anti-crack gypsum-based self-leveling mortar and preparation process thereof
The invention relates to the field of building materials, and particularly discloses anti-crack gypsum-based self-leveling mortar and a preparation process thereof. The anti-crack gypsum-based self-leveling mortar is prepared from the following components in parts by weight: 50 to 200 parts of ordinary Portland cement, 200 to 350 parts of desulfurized gypsum powder, 30 to 100 parts of filler, 50 to 100 parts of sand, 150 to 250 parts of bauxite powder, 10 to 25 parts of polyester fiber, 1 to 3 parts of water reducing agent, 0.5 to 1.0 part of defoaming agent and 0.5 to 1.2 parts of retarder. Micropores are formed in the polyester fiber. According to the anti-crack gypsum-based self-leveling mortar, the desulfurized gypsum powder and the bauxite powder jointly form a gelling system, direct utilization of flue gas desulfurization waste desulfurized gypsum is achieved, resources and energy are saved, micropores of the polyester fibers can increase the water retention property of the fibers, meanwhile, the bonding effect of the surface and the mortar is improved, and the anti-crack effect on the mortar is improved.
本申请涉及建筑材料领域，具体公开了一种抗裂石膏基自流平砂浆及其制备工艺。一种抗裂石膏基自流平砂浆，包括以下重量份的组分：50‑200份普通硅酸盐水泥、200‑350份脱硫石膏粉、30‑100份填料、50‑100份砂子、150‑250份铝矾土粉，10‑25份聚酯纤维、1‑3份减水剂、0.5‑1.0份消泡剂、0.5‑1.2份缓凝剂，所述聚酯纤维内有微孔。本申请的抗裂石膏基自流平砂浆通过脱硫石膏粉和铝矾土粉共同形成胶凝体系，实现对烟气脱硫废料脱硫石膏的直接利用，节约资源和能源，聚酯纤维的微孔，能增加纤维保水性，同时提高表面与砂浆的结合效果，提高对砂浆的抗裂效果。
