| Abstract: | Usually, we use the slag cement of low heat of hydration in the construction of bulk concrete. However, the Portland slag cement of hydration is used in this project because of the high-grade concrete. Here, we use the select materials. The set extra admixture of UEA is instead of proper cement quantity and readjust the concrete bond. In addition, the cold water pipes are layer set to low the heat of hydration. Thus, the temperature of concrete is controlled, and the cracking control technology problems of high-grade bulk concrete are also solved by using Portland slag cement. |
