Hydraulic cementing material utilizing metallurgical solid waste as well as production method and application of hydraulic cementing material
The invention relates to the technical field of solid waste resource utilization, in particular to a hydraulic cementing material utilizing metallurgical solid waste as well as a production method and application of the hydraulic cementing material. The raw materials comprise the following components in parts by weight: 28-32 parts of steel slag tailings, 48-52 parts of slag, 13-17 parts of desulfurized gypsum and 3-7 parts of fly ash, totally 100 parts; wherein the steel slag tailings are steel slag tailings left after converter steel slag is subjected to hot braising and iron selection; the slag is granulated blast furnace slag obtained after blast furnace slag is subjected to water quenching; the desulfurized gypsum is produced by a CaO desulfurization method and takes CaSO4 as a main component; the coal ash is collected after the coal powder is combusted. According to the invention, various metallurgical solid wastes can be consumed synchronously, and good resource utilization is realized; the prepared hydraulic cementing material has good mechanical properties, can replace cement to produce concrete, reduces the production cost of cement and concrete, and has high economic benefits.
本发明涉及固体废弃物资源化利用技术领域，具体涉及一种利用冶金固废的水硬性胶凝材料及其生产方法和应用。以重量份计，原料包括28‑32份钢渣尾渣，48‑52份矿渣，13‑17份脱硫石膏，3‑7份粉煤灰，共100份；其中，钢渣尾渣为转炉钢渣经过热焖、选铁后剩余的钢渣尾渣；矿渣为高炉矿渣经过水淬后的粒化高炉矿渣；脱硫石膏为通过CaO脱硫方法产生的，以CaSO4为主要成分的脱硫石膏；粉煤灰为燃烧煤粉后收集的粉煤灰。本发明可同步消耗各种冶金固废，实现良好的资源化利用；制得的水硬性胶凝材料具有良好的力学性能，可替代水泥生产混凝土，降低水泥和混凝土的生产成本，经济效益高。
