Environment-friendly phosphogypsum cement and preparation method thereof
The invention provides environment-friendly ardealite cement and a preparation method thereof, the ardealite cement is applied to a road base, and the ardealite cement is characterized by being prepared from the following raw materials in percentage by weight: 77.5% of Portland cement clinker, 8% of limestone, 6.5% of ardealite, 4% of coal-fired slag and 4% of slag. The method comprises the following steps: according to the raw material composition and weight ratio of the ardealite cement, obtaining all component raw materials of the ardealite cement, and mixing and weighing to obtain prepared raw materials; the prepared raw materials are subjected to grinding and dust collection treatment and then are lifted to a finished product warehouse, and the ardealite cement is obtained. According to the invention, phosphogypsum is doped before cement grinding, such that characteristics of long setting time, high abundant strength, concrete durability guaranteeing, good adaptability and easy construction are provided, problems of short initial setting time and low later strength of cement are effectively solved, a large amount of industrial waste residue is consumed, and secondary pollution of phosphogypsum is reduced are provided.
本发明提供了一种环保型磷石膏水泥及其制备方法，所述磷石膏水泥应用于一道路基层，其特征在于，所述磷石膏水泥的原料组成及重量配比为：硅酸盐水泥熟料77.5％、石灰石8％、磷石膏6.5％、燃煤炉渣4％、矿渣4％。所述方法包括：根据所述磷石膏水泥的原料组成及重量配比，获得所述磷石膏水泥的各组分原料，混合称重后得到配制好的原料；将所述配制好的原料经过粉磨、收尘处理后提升至成品库，得到磷石膏水泥。通过在水泥粉磨前掺入磷石膏，实现了凝结时间长、富裕强度高，保障混凝土的耐久性，具有适应性好、利于施工的特点，有效解决了水泥初凝时间短、后期强度低的问题，同时还消耗了大量工业废渣，减少磷石膏二次污染的技术效果。
