8 FACTORS AFFECTING SETTING & HARDENING .

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. In actual projects, the setting and hardening process of cement products is accelerated by steam curing and autoclave curing.
