Method for improving sulfate corrosion resistance of gypsum slag cement product
The invention belongs to the field of building materials, and particularly relates to a method for improving sulfate corrosion resistance of a gypsum slag cement product, and the gypsum slag cement product is prepared from desulfurized gypsum, Portland cement, slag powder, fly ash, sodium hydroxide, nano silicon dioxide, a water reducing agent, sand and water. The method is simple in process, free of high-temperature maintenance (low in energy consumption), low in clinker powder mixing amount, low in cost and free of secondary pollution, a large amount of industrial waste residues such as gypsum can be used, and the method has important environmental and economic benefits.
本发明属于建筑材料领域，具体涉及一种提高石膏矿渣水泥制品抗硫酸盐侵蚀性能的方法，所述石膏矿渣水泥制品由脱硫石膏、硅酸盐水泥、矿渣粉、粉煤灰、氢氧化钠、纳米二氧化硅、减水剂、砂和水制备而成，该方法涉及的工艺简单、无需高温养护(能耗少)、熟料粉掺量少、成本低、不会产生二次污染，并能大量使用石膏等工业废渣，具有重要的环境和经济效益。
