8 FACTORS AFFECTING SETTING & HARDENING OF …

 · If the hardening process occurs at a low temperature, the final strength won''t be affected though the development of the strength is slow. But if the temperature is under 0 0 C, the hydration of cement will stop and the strength will not only stop growing but also destroy the structure of cement paste due to the condensation of water.

Low Heat Cement

Out of the four main components in the concrete, C 3 S and C 3 A are the main contributors to the heat generated in the hydration process. The amount of C 3 S and C 3 A are reduced in low heat cement and then the hydration process will be slow. As a result, the rise of the temperature will be limited.
