Abstract
In this paper, the development of early hydration heat and the performance of large temperature difference of mass concrete structures are studied. Five mass concrete samples with two strength grades and five mixing ratios were made. The size of samples is 1000mm1000mm1400mm. Temperature sensors are embedded in the component while the components are constructed. Temperature of early hydration heat temperature rise and instant heating on one side are tested by the sensors. It is found that the early hydration heat temperature rise of self-made crack resistance concrete with internal curing agent or shrinkage reducing agent is lower than that of common commercial concrete. The results of single-side instantaneous temperature rise test show that the temperature changes least on the heating surface of concrete and most in the middle position.
