Portland cement prepared from waste steel slag and preparation method thereof
The invention discloses Portland cement prepared from waste steel slag and a preparation method of the Portland cement, and relates to the technical field of building materials. The modified fiber is prepared from the polyvinyl alcohol fiber, the ferroferric oxide, the silicon dioxide and the ferrocene tube, so that the fracture resistance of the cement is enhanced; a self-repairing microcapsule is prepared from acrylic acid 3-(trimethoxysilyl) propyl ester, 1, 3-diallylurea, epoxy resin E20 and silanetriol glutamate, the uniformity of cement moisture can be improved, microcracks of cement are filled, and the cement has a shrinkage reducing effect; when the concrete cracks, the self-repairing microcapsules are stressed to break and release the core liquid to repair the cracks, so that the cement has a self-repairing effect; and mixing the Portland cement clinker, the steel slag, the modified fibers, the self-repairing microcapsules and other auxiliaries to prepare the Portland cement prepared from the waste steel slag. The Portland cement prepared by the invention has the effects of fracture resistance, shrinkage reduction and self-repairing.
本发明公开了一种利用废弃钢渣制备的硅酸盐水泥及其制备方法，涉及建筑材料技术领域。本发明由聚乙烯醇纤维、四氧化三铁、二氧化硅、二茂铁管制得改性纤维，增强水泥的抗折性能；由丙烯酸3‑(三甲氧硅基)丙酯、1,3‑二烯丙基脲、环氧树脂E20、硅烷三醇谷氨酸酯制得自修复微胶囊，能够提高水泥水分的均匀度、填补水泥的微裂缝，使水泥具有减缩效果；当混凝土产生裂纹时，自修复微胶囊受力破裂并释放芯液，以修补裂缝，使水泥具有自修复效果；硅酸盐水泥熟料、钢渣、改性纤维、自修复微胶囊和其他助剂混合制得利用废弃钢渣制备的硅酸盐水泥。本发明制备的硅酸盐水泥具有抗折、减缩、自修复效果。
