177 Accesses Metrics Abstract The effects of ordinary limestone powder (OLP) and ultrafine limestone powder (UFLP) on the fluidity, setting time, compressive strength, hydration heat and microstructure of calcium sulfoaluminate cement (CSA) were investigated. The results show that finer limestone powder reduces the fluidity and setting time of CSA.
