Abstract：The adaptability of cement produced by using fluorine gypsum as a cement retarder and concrete pumping agent, water reducing agent and other admixtures was studied. The setting time, fluidity,loss over time,and strength were taken as index-es. The results of the study indicate that the adaptability of cement produced with fluoro-gypsum as retarder is better than that using natural gypsum as retarder,which has a smaller loss of fluidity over time. The prepared concrete has a normal slump and stable mechanical properties. The 28-day compressive strength exceeds the design strength by more than 25％.
