Sand-based water-permeable brick prepared from electric-arc furnace steel slag and preparation method thereof

The invention provides a sand-based water-permeable brick prepared from electric-arc furnace steel slag and a preparation method thereof, belonging to the field of utilization of metallurgical solid waste. The water-permeable brick is composed of, by mass, 100 parts of cement, 8-12 parts of a reinforcing agent, 1-10 parts of a thickening agent, 350-550 parts of electric arc furnace steel slag aggregate, 1.5-3.5 parts of an accelerator, 3-5 parts of a coloring agent, 0.3-3.0 parts of a water reducing agent and 15-20 parts of water. After thorough mixing and stirring a plurality of times, the above components are placed in a brick making machine for press forming. The water-permeable brick prepared in the invention has good water permeability, long water permeable duration, high compressivestrength and low density, can be widely applied to municipal projects such as sponge cities, realizes the high-added-value utilization of the electric arc furnace steel slag and protects ecological environment. 本发明提供种电弧炉钢渣制备的
