High-strength superfine iron tailing mixed sand concrete
The invention discloses a high-strength superfine iron tailing mixed sand concrete, and belongs to the technical field of comprehensive utilization of iron tailing resources. The high-strength concrete comprises, by mass, 15-19% of 52.5 grade cement, 20-27% of iron tailing mixed sand, 44-50% of broken stones, 4-8% of an admixture, 6.9-8.1% of water, and a concrete polycarboxylic high-perforcemence water reducer accounting for 0.8-1.5% of the total mass of cement and the admixture, and the strength grade of the high-strength concrete is C60-C80. The high-strength superfine iron tailing mixed sand concrete can reduce pollution of iron tailings to environment, reduces the exploitation quantity and the exploitation energy consumption of natural sand, reduces the concrete production cost, and has obvious economic and social benefits.
