Anti-mildew water-resistant beta-type building phosphogypsum self-leveling mortar and preparation method thereof
The invention relates to anti-mildew water-resistant beta-type building phosphogypsum self-leveling mortar and a preparation method thereof, and belongs to the technical field of gypsum-based mortar and building materials. The mortar is prepared from the following components in parts by weight: 1-7 parts of an anti-mildew waterproof component, 100 parts of beta type building phosphogypsum, 1-4 parts of a retarding water reducing agent, 0.05-0.2 part of a water-retaining agent, 10-20 parts of close packing aggregate, 1-30 parts of composite powder and 25-50 parts of water, the water-resistant self-leveling mortar is prepared by taking beta-type building phosphogypsum as a main raw material, and the water resistance of the phosphogypsum is effectively improved through the synergistic effect of the waterproof component and the composite powder; the high flowability and high strength of the self-leveling gypsum mortar are ensured through the grading technology of the retarding type water reducing agent and the sand in the close packing aggregate; the softening coefficient of the mortar is 0.85 or above, the saturated water absorption rate is 6% or below, the compression/breaking strength is 25-45/6-14 MPa, and the mortar is low in shrinkage, easy and convenient to operate and high in construction efficiency.
本发明涉及一种抗霉耐水β型建筑磷石膏自流平砂浆及其制备方法，属于石膏基砂浆和建筑材料技术领域。所述砂浆由以下重量份的组分组成：抗霉防水组分1～7份、β型建筑磷石膏100份、缓凝型减水剂1～4份、保水剂0.05～0.2份、紧密堆积骨料10～20份、复合粉体1～30份，水25～50份；本发明以β型建筑磷石膏为主要原料制备耐水型自流平砂浆，通过防水组分与复合粉体协同作用，有效提升磷石膏耐水性；通过缓凝型减水剂及紧密堆积骨料中砂的级配技术保证自流平石膏砂浆的大流动性与高强度；所述砂浆软化系数在0.85以上，饱和吸水率在6％以下，抗压/抗折强度在25～45/6～14MPa，低收缩，操作简便，施工效率高。
