| titleOfInvention | Multi-solid waste activated concrete with high-silicon iron ore tailings and preparation method thereof |
| abstract | The disclosure belongs to the field of solid waste resource utilization, and particularly relates to a multi-solid waste activated concrete with high-silicon iron ore tailings and a preparation method thereof. The concrete is prepared from raw materials including 360-380 kg/m3 of a cement, 30-40 kg/m3 of fly ash, 30-40 kg/m3 of a modified ultrafine sand of high-silicon iron ore tailings, 930-950 kg/m3 of a waste stone of tailings, 870-930 kg/m3 of a fine sand of tailings, 160-170 kg/m3 of water, and 4-8 kg/m3 of an additive. The modified ultrafine sand of high-silicon iron ore tailings is prepared by a process including: screening an ultrafine sand of high-silicon iron ore tailings by using a 200-mesh screen; mechanically activating by using an XQM-8 vertical planetary ball mill at an interval of forward and reverse rotation of 10-15 minutes and a rotating speed of 380-395 r/min for two hours; and cooling to room temperature. The concrete according to the disclosure has high total solid waste admixing amount, low cement consumption, ideal concrete impermeability, and high later compressive strength. |
