摘　　要：为分析粉磨方式对水泥材料性能的影响,文中开展了立磨粉磨及联合粉磨两种方式对水泥材料化学组成、物理性能、流动度及水化放热性能影响的研究。结果表明,立磨水泥的初凝时间比联合粉磨水泥减少25%,终凝时间比联合粉磨水泥增加20%;联合粉磨水泥的比表面积较立磨水泥降低4.8%,联合粉磨水泥的标准稠度用水量较立磨水泥增加8%;立磨水泥的3 d抗折强度比联合粉磨水泥低4.7%,3 d抗压强度比联合粉磨水泥低8.6%;立磨水泥的水泥净浆扩展度和水泥胶浆扩展度比联合粉磨水泥分别高出12.9%、5.4%;联合粉磨水泥的水化放热速率比立磨水泥的水化放热速率高50%。In order to analyze the effects of grinding methods on the properties of cement materials,the effects of vertical grinding and combined grinding methods on the chemical composition,physical properties,fluidity and hydration heat release properties of cement materials were studied.The results show that the initial setting time of vertical grinding cement is 25%lower and the final setting time is 20%higher than that of combined grinding cement.The specific surface area of combined ground cement is 4.8%lower than that of vertical ground cement,and the water consumption of standard consistency of combined ground cement is 8%higher than that of vertical ground cement.The 3 d flexural strength and compressive strength of vertical grinding cement are 4.7%lower than those of combined grinding cement,and 8.6%lower than those of combined grinding cement.The expansion degree of cement paste and cement paste of vertical grinding cement is 12.9%and 5.4%higher than that of combined grinding cement,respectively.The hydration heat release rate of combined grinding cement is 50%higher than that of vertical grinding cement.
