【 摘 要 】

In the paper, phosphorus slags were the main raw material.Orthogonal experiment method and single factor experiment method were used to determine the optimal process parameters for exciting phosphorus slag portland cement. The results show that the phosphorus slag mixture contained 0.05-0.07% triethanolamine,1.5-2% NaCl,1.5-1.8% Na2SO3. The phosphorus slag-based cementitious material was prepared by using the superior phosphorus slag active excitation scheme. The early and late activity indexes of the phosphorus slag-based can effectively support the large-scale resource utilization of phosphorus slag.
