To know the temperature rise characteristics of concrete is the premier step for engineers to establish proper measures to control the maximum temperature as well as thermal gradient of concrete structures.
This phenomenon is against the common belief of many engineers that high-strength concrete, which is normally proportioned with lower W/C ratio, gives higher temperature rise.
