    Sep 22 2016 · For example the increase of C3A can speed up the setting and hardening rate of cement and the heat of hydration is high at the same time. Generally speaking if mixed materials are added into the cement clinker the anti-erosion will increase and the heat of hydration and the early strength will decrease.
