铁铝酸盐水泥专用速凝剂的研究

Study of dedicated accelerating agent for ferrous aluminate cement

本文通过试验较全面地研究了各种速凝剂对铁铝酸盐水泥的适应性,结果表明,仅JA速凝剂具有明显的促凝效果。在此基础上,又研究了不同水灰比条件下,JA速凝剂对铁铝酸盐水泥凝结时间的影响情况,同时探索了该速凝剂对铁铝酸盐水泥强度的影响规律。

In this paper, the adapatability of various accelerating agents to the ferrous aluminate cement is described in details. The results show that only the JA accelerating agent can bring about the remarkable accelerating effect. Based on this result, the effect of the JA accelerating agent on the cement setting time is analyzed under different water cement ratios, and the rules governing such effect are also presented.
