Anti-crack gypsum-based self-leveling mortar and preparation method thereof
The invention discloses anti-crack gypsum-based self-leveling mortar and a preparation method thereof, and relates to the technical field of building materials. The anti-cracking gypsum-based self-leveling mortar is prepared from the following raw material components in parts by weight: 100 parts by mass of mixed cement, 200 to 350 parts by mass of alpha-high-strength gypsum, 260 to 300 parts by mass of steel slag sand, 140 parts by mass of steel slag powder, 1 to 3 parts by mass of a water reducing agent, 10 to 25 parts by mass of activated polyacrylonitrile fiber, 190 parts by mass of water and 0.5 to 1 part by mass of a de-foaming agent, the mixed cement is obtained by mixing Portland cement and aluminate cement according to the mass ratio of 1: (0.08-0.1); the activated polyacrylonitrile fibers are obtained by activating polyacrylonitrile fibers in a hydroxylamine hydrochloride solution; the particle size of the steel slag sand is 0.15 to 0.60 mm; and the particle size of the steel slag powder is 0.09-0.2 mm.
本发明公开了一种抗裂石膏基自流平砂浆及其制备方法，涉及建筑材料技术领域；本发明的抗裂石膏基自流平砂浆，按重量份数计，原料组分包括：100质量份混合水泥、200～350质量份α‑高强石膏、260～300质量份钢渣砂、140质量份钢渣粉、1～3质量份减水剂、10～25质量份活化聚丙烯腈纤维、190质量份水、0.5～1质量份消泡剂；所述混合水泥是由硅酸盐水泥、铝酸盐水泥按质量比1：0.08～0.1混合得到；所述活化聚丙烯腈纤维是将聚丙烯腈纤维在盐酸羟胺溶液中活化得到；所述钢渣砂的粒径为0.15～0.60mm；所述钢渣粉的粒径为0.09～0.2mm。
