Iron tailings mixing sand concrete
The present invention discloses an iron tailings mixing sand concrete, which comprises, by mass, 16-20% of 52.5-grade cement, 22-27% of iron tailings mixing sand, 45-48% of crushed stone, 5.5-6.5% of an admixture, 7.3-8.1% of water, and 0.2-0.3% of a polycarboxylic acid efficient water reducer. The iron tailings mixing sand concrete of the present invention has characteristics of good water retention property, easy vibration molding, and good workability.
