%X 本文研究了不同矿渣含量对磷渣基碱激发胶凝材料的抗压强度和工作性能的影响。其中，矿渣掺入量为0%、10%、20%、30%、40%和50%，碱激发剂为1.3M水玻璃溶液，碱当量为5%，经过3天、7天和28天养护。发现掺入矿渣能生成更多的C-(A)-S-H，大幅提升碱激发磷渣基胶凝材料的抗压强度，在相同的碱性条件下矿渣能解聚出满足缩聚反应浓度的Si-O键和Al-O键和大量Ca离子，从而在更短的时间内完成缩聚反应，缩短凝结时间和降低流动性。<br />
This article investigates the influence of different slag contents on the compressive strength and workability of phosphorus slag based alkali activated cementitious materials. Among them, the amount of slag added is 0%, 10%, 20%, 30%, 40%, and 50%, the alkaline activator is 1.3M water glass solution, the alkali equivalent is 5%, and it is cured for 3, 7, and 28 days. It was found that adding slag can generate more C-(A)-S-H, significantly improving the compressive strength of alkali activated phosphorus slag based cementitious materials. Under the same alkaline conditions, slag can depolymerize Si-O bonds and Al-O bonds that meet the concentration of condensation reaction, as well as a large amount of Ca<sup>2+</sup>, thus completing the condensation reaction in a shorter time, reducing the setting time and fluidity.
