摘要:
The development of eco-friendly and efficient alternative binder to conventional Portland cement is a challenging issue that deserves to be paid more attention. The mineral additive-modified magnesium potassium phosphate cement mixture was introduced in sediment solidification recycled as alternative roadbed material. The feasibility of mineral additive-MKPC blend in solidifying sediment and its mechanical performance were probed into deeply through unconfined compressive strength, durability, microstructural and mineralogical tests. The results demonstrated that it existed an optimal mineral ...
