Composite mineral admixture for concrete
The invention discloses a composite mineral admixture for concrete. The composite mineral admixture comprises the following components in percentage by weight: 15-20% of cement clinker, 30-40% of mineral powder, 8-15% of silica fume, 20-30% of limestone powder and 15-25% of fly ash, wherein the limestone powder is obtained by processing mining debris. According to the composite mineral admixture disclosed by the invention, the gel material is added at a proportion of 20-40%, so that the economic benefits are remarkable while the production needs of high-performance concrete and high-strength concrete are met, and the economic and social benefits are also very high; by adopting the composite mineral admixture, the use of cement is reduced; and by mass utilization of industrial wastes such as mineral powder, limestone powder, fly ash and relatively low-quality silica fume, the waste of resources is reduced, and the sustainable development of the concrete industry is promoted.
