Composite cementing material applied to cement concrete
The invention relates to a composite cementing material applied to cement concrete, and belongs to the technical field of building materials, the composite cementing material comprises fly ash, mineral powder, coal gangue and vanadium-titanium slag; the specific surface area of the composite cementing material is 800-1000 m < 2 >/kg, d97 is less than 30 [mu] m, and d50 is less than 7 [mu] m; the method can be widely applied to cement and concrete production, and is particularly suitable for the fields of high-strength and high-performance concrete, autoclave-free precast concrete members, special engineering and the like. The composite cementing material can reduce the production cost of cement concrete and improve the quality of cement and concrete at the same time. On one hand, new utilization value is given to industrial solid waste, and on the other hand, as a high-activity admixture, the problem of resource scarcity of existing admixtures (such as limestone and the like) can be effectively relieved. On the premise of ensuring the performance of the cement concrete, the cost of the cement concrete can be greatly reduced, and the utilization value of industrial solid wastes is improved.
本发明涉及一种应用于水泥混凝土中的复合胶凝材料，属于建材技术领域，该复合胶凝材料包括：粉煤灰、矿粉、煤矸石和钒钛矿渣；所述复合胶凝材料的比表面积800～1000m2/kg，d97＜30μm，d50＜7μm；可广泛应用于水泥和混凝土生产中，尤其适用于高强高性能混凝土、免压蒸预制混凝土构件、特种工程等领域。这种复合胶凝材料能够降低水泥混凝土生产成本同时提高水泥及混凝土质量。一方面给予工业固废新的利用价值，另一方面作为一种的高活性掺合料，可以有效缓解现有掺合料(如石灰石等)资源稀缺的问题。在保证水泥混凝土的性能的前提下，可以大大地降低水泥混凝土成本，提高工业固废的利用价值。
