Aiming at the problem of high carbon emission and high cost of traditional cementitious material cement, a new type of cement-fly ash-carbonized steel slag ternary cementitious system (proportion of cement 40%, carbonated steel slag 30%, fly ash 30%) was proposed. Through the synergistic use of industrial solid waste, the goal of low carbon and low cost filling can be achieved. The results are concluded as follows. The reaction between CO2 and active minerals in carbonated steel slag achieves carbon fixation and performance optimization. The flowability of the filling slurry in the cement-fly ash-carbonated steel slag system is better than that in the cement system. The ball rolling effect of fly ash and the optimized gradation of fine particles of carbonated steel slag synergistically enhance the rheological properties of the slurry. Due to the rapid reaction rate of cement, the 3 d compressive strength ratio of cement-fly ash-carbonated steel slag-based backfill to cement-based backfill is 0.45 to 0.65, while fly ash undergoes sustained hydration in the later stage to form hydration gel, the 7 d and 28 d compressive strengths ratio is increased to more than 0.80. The production cost of cement-fly ash-carbonated steel slag system is 22% lower than that of cement system, and the carbon emission is reduced by 63.6%. Through the resource utilization of steel slag, the problems of solid waste storage, filling cost and carbon emission have been solved simultaneously, which provides an innovative technical path for the goal of carbon neutrality in mining industry.

针对传统胶凝材料水泥具有高碳排放、高成本的问题,提出了一种新型水泥-粉煤灰-碳化钢渣三元胶凝体系(配比为水泥40%、碳化钢渣30%、粉煤灰30%),通过协同利用工业固废,实现低碳、低成本充填目标。结果表明:CO2与碳化钢渣中活性矿物的反应实现固碳与性能优化;水泥-粉煤灰-碳化钢渣体系充填料浆流动性优于水泥体系,粉煤灰的“滚珠效应”及碳化钢渣微细化颗粒优化级配协同增强料浆的流变性能;由于水泥具有较快的反应速率,水泥-粉煤灰-碳化钢渣基充填体与水泥基充填体的3 d抗压强度比值为0.45~0.65,而粉煤灰后期持续水化生成水化凝胶,7 d和28 d的抗压强度比值提升至0.80以上;水泥-粉煤灰-碳化钢渣体系生产成本较水泥体系降低22%,碳排放减少63.6%。通过钢渣资源化利用,同步解决固废堆存、充填成本与碳排放难题,为矿业碳中和目标提供创新技术路径。

针对传统胶凝材料水泥具有高碳排放、高成本的问题,提出了一种新型水泥-粉煤灰-碳化钢渣三元胶凝体系(配比为水泥40%、碳化钢渣30%、粉煤灰30%),通过协同利用工业固废,实现低碳、低成本充填目标。结果表明:CO2与碳化钢渣中活性矿物的反应实现固碳与性能优化;水泥-粉煤灰-碳化钢渣体系充填料浆流动性优于水泥体系,粉煤灰的“滚珠效应”及碳化钢渣微细化颗粒优化级配协同增强料浆的流变性能;由于水泥具有较快的反应速率,水泥-粉煤灰-碳化钢渣基充填体与水泥基充填体的3 d抗压强度比值为0.45~0.65,而粉煤灰后期持续水化生成水化凝胶,7 d和28 d的抗压强度比值提升至0.80以上;水泥-粉煤灰-碳化钢渣体系生产成本较水泥体系降低22%,碳排放减少63.6%。通过钢渣资源化利用,同步解决固废堆存、充填成本与碳排放难题,为矿业碳中和目标提供创新技术路径。

Aiming at the problem of high carbon emission and high cost of traditional cementitious material cement, a new type of cement-fly ash-carbonized steel slag ternary cementitious system (proportion of cement 40%, carbonated steel slag 30%, fly ash 30%) was proposed. Through the synergistic use of industrial solid waste, the goal of low carbon and low cost filling can be achieved. The results are concluded as follows. The reaction between CO2 and active minerals in carbonated steel slag achieves carbon fixation and performance optimization. The flowability of the filling slurry in the cement-fly ash-carbonated steel slag system is better than that in the cement system. The ball rolling effect of fly ash and the optimized gradation of fine particles of carbonated steel slag synergistically enhance the rheological properties of the slurry. Due to the rapid reaction rate of cement, the 3 d compressive strength ratio of cement-fly ash-carbonated steel slag-based backfill to cement-based backfill is 0.45 to 0.65, while fly ash undergoes sustained hydration in the later stage to form hydration gel, the 7 d and 28 d compressive strengths ratio is increased to more than 0.80. The production cost of cement-fly ash-carbonated steel slag system is 22% lower than that of cement system, and the carbon emission is reduced by 63.6%. Through the resource utilization of steel slag, the problems of solid waste storage, filling cost and carbon emission have been solved simultaneously, which provides an innovative technical path for the goal of carbon neutrality in mining industry.
