Hydration Degree of Cement with Different Mineral Admixture of 3

By experiment,hydration degree of cement of water to cement ratio is the 0. 31 and the hydration degree of cement added with different mineral admixture under the 3 ℃,were studied. And to study the effect of mineral admixture on cement hydration and the cement hydration rules of add various mineral admixtures,to provide reference for quantitative study of cement hydration. Properties of the raw material were tested,hydration heat of cement with the different mineral admixture and different cement pastes ratio by measure and hydration degree calculation. The test results show that,after cement was replaced with fly ash and slag,the hydration degree of blended cement is lower than Portland cement.However,the reduction degree of hydration is not proportional with the addition of fly ash or slag,fly ash to reduce the degree of hydration effect higher than slag. At the same time the fitted curve of cement hydration rules function to add the mineral admixture of 3 ℃. Through the comparison of test data,the function curve is in higher agreement with the cement hydration regulation of adding mineral admixture.
