High-water-resistance gypsum-based cementing material and preparation method thereof
The invention provides a high-water-resistance gypsum-based cementing material and a preparation method thereof, and relates to the technical field of cementing materials, the high-water-resistance gypsum-based cementing material comprises the following raw materials by mass: 60%-70% of fluorgypsum, 15%-25% of fly ash, 9%-15% of cement, 3%-6% of slag powder, 0.04%-0.1% of modified silicon oxide, 0.1%-0.5% of CSH seed crystal, a pH regulator and an activator; wherein the pH regulator accounts for 1%-5% of the total mass of the fluorgypsum and the fly ash, and the exciting agent accounts for 0.5%-3% of the total mass of the fluorgypsum and the fly ash. The fluorgypsum is used as a raw material, the fly ash, the slag powder and a small amount of cement are used as auxiliary materials, and the modified silicon oxide with hydrophilic groups and hydrophobic groups is added, so that the problem that a fluorgypsum-based material is not waterproof is solved, and the fluorgypsum-based cementing material can be massively applied in a high-humidity environment.
本发明提供一种高耐水性石膏基胶凝材料及其制备方法，涉及胶凝材料技术领域，按质量比计，所述高耐水性石膏基胶凝材料包括如下原料：氟石膏60％～70％、粉煤灰15％～25％、水泥9％～15％、矿渣粉3％～6％、改性氧化硅0.04％～0.1％、CSH晶种0.1％～0.5％，还包括pH调节剂、激发剂；其中pH调节剂占氟石膏、粉煤灰总质量的1％～5％，激发剂占氟石膏、粉煤灰总质量的0.5％～3％。本发明以氟石膏为原料，辅以粉煤灰、矿渣粉和少量水泥，并加入了具有亲水基团和疏水基团的改性氧化硅，解决了氟石膏基材料不耐水的问题，使氟石膏基胶凝材料得以在高湿度环境下大量运用。
