Abstract The TAMAIR eight-channel isothermal calorimeter was used to study the hydration rate and heat release of general P·O 42.5 and P·O 52.5 cements, as well as special low-heat cement, sulphate aluminate cement, and oil well cement at 20 ℃, 30 ℃, 40 ℃ and 50 ℃, in order to explore and evaluate the impact of temperature changes on various commonly used and special cements, providing data reference for cement concrete construction in different temperature environments.
