利用高钙粉煤灰生产粉煤灰水泥的试验研究

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 Ｃａ Ｏ 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３４０～４００ ｍ ２ ／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。

Experimental Research of Using High-Calcium Fly Ash Produ ced Fly Ash Cement

Studied the influence of the fineness of the cement with high calcium fly ash and active agent on the physical properties. The results 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 hydration 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 m\ 2/kg specific surface area can be stably produced.
