Green unfired gypsum-based waterproof cementing material and preparation method thereof
The invention relates to the technical field of building materials, discloses a green unfired gypsum-based waterproof cementing material, and further discloses a preparation method of the green unfired gypsum-based waterproof cementing material, and the green unfired gypsum-based waterproof cementing material comprises the following components in parts by mass: 50 parts of hemihydrate gypsum, 5-20 parts of barium hydroxide octahydrate, 5-20 parts of glass powder, 10-40 parts of slag and 1.5 parts of an additive. Comprising the following steps: S1, mechanically crushing dihydrate gypsum, and drying to prepare semi-hydrated gypsum; breaking the glass; s2, packaging the semi-hydrated gypsum, the barium hydroxide octahydrate, the glass powder and the slag into bags; s3, packaging the protein gypsum retarder and polyethylene glycol-4000 into bags, and packaging the polycarboxylic acid water reducer into bags; and S4, packaging in a large bag. High-temperature calcination is not needed, energy consumption is low, and aging is not prone to occurring; the semi-hydrated gypsum, the glass powder and the slag in the cementing material are all recycled industrial byproducts, so that the raw material cost is low, and the cementing material is green and environment-friendly; the waterproof effect is excellent, the compressive strength is high, and the durability is good.
本发明涉及建筑材料技术领域，公开了一种绿色免烧的石膏基防水胶凝材料，按质量份组成如下：50份半水石膏、5～20份八水氢氧化钡、5～20份玻璃粉、10～40份矿渣以及1.5份外加剂，还公开了一种绿色免烧的石膏基防水胶凝材料的制备方法，包括以下步骤：S1、将二水石膏机械破碎、烘干制成半水石膏；将玻璃破碎；S2、将半水石膏、八水氢氧化钡、玻璃粉以及矿渣，包装成袋；S3、将蛋白质类石膏缓凝剂和聚乙二醇‑4000包装成袋，将聚羧酸减水剂包装成袋；S4、再包装在大袋中。本发明无需进行高温煅烧，能耗低，不易老化；且胶凝材料中的半水石膏、玻璃粉和矿渣均为工业副产物的再利用，原料成本低，绿色环保；具有优异的防水效果，抗压强度高，耐久好。
