Mineral admixture for ultra-high performance concrete and preparation method thereof
The invention belongs to the technical field of cement concrete, and particularly relates to a mineral admixture for ultra-high performance concrete and a preparation method of the mineral admixture. The invention provides a high-adaptability mineral admixture for ultra-high performance concrete and a preparation method of the high-adaptability mineral admixture. The high-adaptability mineral admixture is prepared by optimizing raw material composition, solid waste powder, mix proportion, particle dispersion process and adaptability. The inherent defects of low strength, large viscosity, long setting time, large shrinkage and the like of a traditional ultra-high performance concrete mineral admixture are overcome, meanwhile, the ultra-high performance concrete admixture is prepared from the solid waste such as the fly ash, the fly ash floating beads and the carbide slag, and the carbon emission of the ultra-high performance concrete is reduced.
本发明属于水泥混凝土技术领域，具体涉及一种超高性能混凝土用的矿物掺合料及其制备方法。本发明提供了一种超高性能混凝土用的高适配性矿物掺合料及制备方法，通过原材料组成优化、固体废弃物粉体优化、配合比优化、颗粒分散工艺优化和适配性优化，改善了传统超高性能混凝土矿物掺合料强度低、粘度大、凝结时间长、收缩大等固有缺点，同时本发明采用粉煤灰、粉煤灰漂珠和电石渣等固体废弃物为原材料制备超高性能混凝土掺合料，降低了超高性能混凝土的碳排放量。
