| 中文摘要:以28天最优配方激发酸性矿渣粉为胶凝材料进行试验，分析了质量浓度、灰砂比、减水剂掺量、搅拌时间4个因素对砂浆流动度、失水率、干缩率、抗压强度的影响规律，并且针对灰砂比这一因素将水泥与矿渣粉胶凝材料浆液性能进行了对比。最后选取了合适的比例进行正交试验来优化各因素组合，使砂浆综合性能达到最优。 |

| Abstract:The experiment was made on acid slag powder as cementitious material, which was inspired based on the best recipes for 28 days. Analysis was made on the influence law of mass concentration, cement-sand ratio, dosage of water reducing agent and stirring time on the mortar fluidity, water loss rate, shrinkage and compressive strength; and according to the cement-sand ratio, comparison was made on the slurry performance of cement and slag powder cementitious material. Finally, the appropriate proportion was selected for orthogonal experiment to optimize various factors combination to achieve optimal comprehensive performance of the mortar. |
