Water-resistant and mildew-resistant gypsum mortar and preparation method thereof
The invention belongs to the technical field of gypsum mortar, and particularly relates to water-resistant and mildew-resistant gypsum mortar, which is prepared from the following raw materials: semi-hydrated gypsum, type II anhydrous calcium sulfate, ground slag micro powder, calcium hydroxide, a retarder, a mildew preventive, aggregate and water.The water-resistant and mildew-resistant gypsum mortar has the beneficial effects that the semi-hydrated gypsum and the type II anhydrous calcium sulfate are used as cementing materials; a stable and compact structure is formed through a composite hydration reaction, so that the strength and the water resistance of the mortar are improved; the ground slag micro powder is adopted as an active admixture, and the compactness and durability of the mortar are improved by filling pores and promoting hydration reaction; calcium hydroxide is used as an alkaline admixture, and the pH value of the mortar is increased, so that the growth of mould is inhibited, and the mould-proof performance of the mortar is improved.
本发明属于石膏砂浆技术领域，具体是一种耐水抗霉变石膏砂浆，包括以下原料：半水石膏、Ⅱ型无水硫酸钙、地炉渣微粉、氢氧化钙、缓凝剂、防霉剂、骨料和水，本发明所具有的有益效果是采用半水石膏和Ⅱ型无水硫酸钙作为胶凝材料，通过复合水化反应形成了稳定而致密的结构，提高了砂浆的强度和耐水性；采用地炉渣微粉作为活性掺合料，通过填充孔隙和促进水化反应，增加了砂浆的密实度和耐久性；采用氢氧化钙作为碱性掺合料，通过提高砂浆的pH值，抑制了霉菌的生长，增加了砂浆的防霉性能。
