Steel slag doped premixed concrete and preparation method thereof
The invention discloses a steel slag doped premixed concrete and a preparation method thereof. The preparation method comprises the steps that citral is added into a polypropylene glycol solution to modify polypropylene glycol, then calcium carbonate, hydrochloric acid, steel slag, rubber powder and other substances are added to improve the mechanical property of polypropylene glycol, and porous fibers are prepared through electrostatic spinning; the porous fibers are modified by using a silane coupling agent, and microorganisms are loaded on the modified fibers to obtain modified fibers; calcium lactate is wrapped with urea-formaldehyde resin to prepare calcium lactate microcapsules; and calcium lactate microcapsules, modified fibers, cement and other materials are mixed and stirred to prepare the steel slag doped premixed concrete. The invention provides a steel slag doped premixed concrete and a preparation method thereof. The ratio and reaction time are reasonably controlled in thepreparation process, the mechanical properties and impermeability of the prepared concrete sample are effectively improved, and meanwhile, the steel slag doped premixed concrete also has certain self-repairing capability, so that manpower, material resources and financial resources are greatly saved, and the practicability is relatively high.
本发明公开了一种掺钢渣预拌混凝土及其制备方法，首先在聚丙烯醇溶液中添加柠檬醛对聚丙烯醇进行改性，再加入碳酸钙、盐酸、钢渣、橡胶粉等物质改善其力学性能，通过静电纺纺丝制成多孔纤维；利用硅烷偶联剂对多孔纤维进行改性，将微生物负载在改性纤维上制得改性纤维；利用脲醛树脂包裹乳酸钙，制成乳酸钙微胶囊；将乳酸钙微胶囊和改性纤维与水泥等物料混合搅拌制成掺钢渣预拌混凝土；本发明中提供了一种掺钢渣预拌混凝土及其制备方法，制备过程中合理控制配比和反应时间，制备得到的混凝土试样的力学性能和抗渗性能得到有效改善，同时还具备一定的自修复能力，大大节省了人力物力财力，具有较高的实用性。
