Hydration of cement is exothermic process that generates heat. The table below shows the heat generate with different cement components. Which component is recommended to build a dam wall which is a large amount of cement block? a. None of the above b. C2S only which generate less heat and less thermal stress Oc. A mixture of Low heat cements to avoid thermal stress and high energy released and other factors should be considered. d. C3A because it generates large amount of heat and dry the block faster.
