   研究了高钙粉煤灰水泥的细度及活性激发剂对其物理性能的影响。研究结果表明，高钙粉煤灰水泥的安定性和各龄期的抗折、抗压强度均随着水泥的细度的提高和活性激发剂的掺入而提高，活性激发剂具有加速水泥矿物和f-CaO水化的作用。采用525#熟料，掺加30%的高钙粉煤灰时，水泥的比表面积在340～400m2/kg和掺入1%的活性激发剂，能够稳定生产425#高钙粉煤灰水泥。

Zhang Shixian　Zhou Tao　Wang Zhiquan

Abstract:　Studied the influence of the fineness of the ceme nt with high-calcium fly ash and active agent on the physical properties. The r esults showed that the flexible and compressive strengths at different ages and stability of the cement with high-calcium fly ash increased with the increasing of cement fineness and the adding of active agent, which accelerated the hydrat ion of the cement minerals and f-CaO. By using 525# clinker, in the case that adding 30% high-calcium fly ash and 1% active agent, 425# high-calcium fly ash cement with 340～400 m2/kg specific surface area can be stably produced .
Key words:　high-calcium fly ash；　fineness；　stability； 　active agent
