   研究了高鈣粉煤灰水泥的細(xì)度及活性激發(fā)劑對(duì)其物理性能的影響。研究結(jié)果表明，高鈣粉煤灰水泥的安定性和各齡期的抗折、抗壓強(qiáng)度均隨著水泥的細(xì)度的提高和活性激發(fā)劑的摻入而提高，活性激發(fā)劑具有加速水泥礦物和f-CaO水化的作用。采用525#熟料，摻加30%的高鈣粉煤灰時(shí)，水泥的比表面積在340～400m2/kg和摻入1%的活性激發(fā)劑，能夠穩(wěn)定生產(chǎn)425#高鈣粉煤灰水泥。

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
