Method for preparing ultra-high performance concrete admixture by using concrete waste slurry
The invention relates to the technical field of buildings, in particular to a method for preparing an ultra-high-performance concrete admixture from concrete waste slurry, and solves the problem that the performance of concrete is reduced when the ultra-high-performance concrete admixture is used as a high-performance concrete admixture after the ultra-high-performance concrete admixture is doped into the concrete. The early strength of the ultra-high performance concrete is improved, the recycling and fine high-end utilization of the concrete waste cement paste are realized, the bleeding rate of the concrete is obviously reduced, the workability, the strength and the durability of the concrete are improved, and the concrete has good anti-freezing, cold-resistant and waterproof properties and the like; according to the concrete admixture, the dispersity of the admixture to concrete particles is improved, the water consumption is reduced, the performance of the concrete after the admixture is added is enhanced, the corrosion resistance, workability and other performance of the concrete are improved, the dispersion of the concrete particles can be promoted, the strength and workability of the concrete are enhanced, and the corrosion resistance, acid resistance, tax reduction and other performance of the concrete are improved.
本发明涉及建筑技术领域,尤其涉及一种利用混凝土废浆制备超高性能混凝土外加剂的方法,本发明制成的超高性能混凝土外加剂在掺入混凝土后解决了其作为高性能混凝土掺合料引起的混凝土性能降低的问题,确保了超高性能混凝土早期强度的提高,实现了混凝土废弃水泥浆的资源化和精细高端化利用,并明显地降低混凝土的泌水率,改善混凝土的工作性、强度和耐久性,使混凝土具良好的有抗冻、抗寒、防水等性能,提高了外加剂对混凝土颗粒的分散度,减少用水量,强化加入外加剂后混凝土的性能,使混凝土的耐腐蚀性、工作性等性能提高,可促进混凝土颗粒的分散,增强混凝土的强度和工作性,提升混凝土的耐腐蚀、耐酸性和减税性等性能。
