石灰石硅酸盐水泥的研究

STUDY ON PORTLAND LIMESTONE CEMENT

研究了石灰石硅酸盐水泥中石灰石掺入量及水泥细度对水泥胶砂强度的影响。结果表明，该品种水泥的物理力学性能与普通硅酸盐水泥相似。通过微观分析，证实了石灰石硅酸盐水泥早期水化速度较快，具有早期强度较高的特点。

The effects of added limestone contents in portland limestone cement and fineness of cement grinding on strength of the cement mortar were investigated. The experimental results show that the physical mechanical performance of the cement is similar to that of ordinary portland cement. The results of micro analyses indicated that the hydration speed of portland limestone cement is faster, as well as the strength of the cement is higher at early stage.
