Magnesium-based composite cement based on high-activity magnesium oxide powder and preparation method thereof
The invention aims to solve the problems that magnesium phosphate cement, magnesium oxysulfate cement and magnesium oxychloride cement are poor in water resistance, the setting time cannot be controlled and field construction is not facilitated in the prior art, provides magnesium-based composite cement based on high-activity magnesium oxide powder and a preparation method of the magnesium-based composite cement, and belongs to the technical field of cement materials. The magnesium-based composite cement comprises the following raw materials: magnesium sulfate or magnesium chloride or solublephosphate, a boron-containing compound, light calcined magnesia powder and iron tailings or boron mud. Furthermore, the raw materials also contain a naphthalene water reducer and glass fibers. Magnesium oxysulfate or magnesium oxychloride or magnesium phosphate cement is used as a binder, a boron-containing compound is used as a modifier, iron tailings or boron mud is used as an active admixture,a naphthalene water reducer is used as a water reducer, glass fibers are used as a toughening material, the water resistance and strength of the prepared cement product are improved, and the water resistance and strength of the cement product are improved, and by adjusting the formula and controlling the setting time. the different construction scenes can be met.
本发明的目的是为了解决现有技术中磷酸镁水泥、硫氧镁水泥和氯氧镁水泥耐水性差，凝结时间无法掌控，不利于现场施工的问题，提供了一种基于高活性氧化镁粉的镁基复合水泥及其制备方法，属于水泥材料技术领域。本发明的镁基复合水泥的原料含有：硫酸镁或氯化镁或可溶性磷酸盐，含硼化合物，轻烧氧化镁粉，以及铁尾矿或硼泥。进一步的，原料还含有萘系减水剂和玻璃纤维。本发明以硫氧镁或氯氧镁或磷酸镁水泥为粘结剂，以含硼化合物为改性剂，以铁尾矿或硼泥为活性掺合料，以萘系减水剂为减水剂，以玻璃纤维为增韧材料，制得的水泥产品耐水性和强度性能提高，通过调整配方，控制凝结时间，能够满足不同的施工场景。
