摘　　要：为使矿渣在钢纤维喷射混凝土中得到合理有效的利用,充分发挥矿渣改善混凝土性质的作用,在改变水灰比、速凝剂掺入比例两个因素的条件下,找出适合钢纤维喷射混凝土的凝结时间较短、粘结性较好的矿渣掺入范围。矿渣掺量规律性的研究对钢纤维喷射混凝土理论研究及施工有一定的参考价值。In order to have a rational and efficient utilization of slag in steel fiber shotcrete, to fully play the role of the slag to improve the concrete quality, the paper found the short setting time suitable for the steel fiber shotcrete and the slag admixture scale with a good binding under the conditions of the changed water and cement ratio and the admixture ratio of quick -setting agent. The study on the slag admixture law will have a certain reference value to the theoretical study and construction of the steel fiber shotcrete.
