The invention discloses a high-dosage phosphogypsum cement clinker cementing material and an application thereof. The high-volume phosphogypsum cement clinker cementing material is prepared by mixingand grinding the following components in percentage by weight: 24%-52% of phosphogypsum cement clinker, 23%-51% of cement, 8% of phosphorus slag micro powder, 17% of fly ash and 1%-2% of an externallydoped powdery phosphorus excitant, and then doping 0.5%-0.7% of an aqueous phosphorus excitant. The invention further provides an application of the high-dosage phosphogypsum cement clinker cementingmaterial in preparation of concrete. In the application, the concrete is prepared from sand, stones, water and the high-dosage phosphogypsum cement clinker cementing material. According to the invention, the mixing amount of the phosphogypsum cement clinker in the concrete can be increased, the mixing amount of cement in the concrete is reduced, and when the mixing amount of the phosphogypsum cement clinker in the concrete cementing material is 52%, the concrete cementing material has working performance, and initial setting and final setting meet the production requirements of enterprise concrete.
本发明公开了一种高掺量磷石膏水泥熟料胶凝材料及其应用，该高掺量磷石膏水泥熟料胶凝材料按重量百分比计算，是由24％～52％磷石膏水泥熟料、23％～51％水泥、8％磷渣微粉、17％粉煤灰与外掺1％～2％粉剂磷系激发剂混合研磨，再外掺0.5％～0.7％水剂磷系激发剂制成。本发明还提出高掺量磷石膏水泥熟料胶凝材料在制备混凝土中的应用。在该应用中，混凝土由砂子、石子、水和高掺量磷石膏水泥熟料胶凝材料制成。本发明可以提高磷石膏水泥熟料在混凝土中的掺量，降低混凝土中水泥的掺量，在混凝土胶凝材料中磷石膏水泥熟料的掺量为52％时，具有工作性能及初凝和终凝满足企业混凝土的生产要求。
