复合胶凝材料中水泥水化程度的实验研究

Experimental study on degree of cement hydration in composite cementitious material

在对复合胶凝材料水泥水化程度的实验研究中,寻找一种简便计算方法,通过采用图像分析法和基于矿物掺合料反应程度的Ca(OH)_2定量修正法定量表征出复合体系中水泥水化程度,确定该计算方法的准确性。结果表明:计算方法得到的水泥水化程度计算结果与通过图像分析法和Ca(OH)_2定量修正法得到的水泥水化程度实验结果相比较,两者的相对误差都小于8%,说明该计算方法在相对误差范围内具有可行性,为水泥水化程度的研究提供了一种简便的途径。

A simple calculation method was presented for experimental study on the degree of cement hydration in composite cementitious material.To verify the accuracy of the method, the image analysis and the Ca（ OH）2 quantitative amendment methods were used to characterize the cement hydration degree. Results showed that when the calculated results were compared with the experimental ones obtained from the image analysis and Ca（OH） 2 quantitative amendment methods, both relative errors were less than 8%. The calculation method provided an easy way for the research of the cement hydration degree.
