The hydration energy increased gradually and obtained a saturated value at the end.

水合能逐渐升高并最终趋于平衡，平衡值仍低于体相水的势能。

The results show that the early strength and the permeability of concrete can be improved effectively, and the hydration heat can be reduced and the hot peak value at the early age can be postponed.

结果表明：掺加激发剂能有效改善大掺量粉煤灰混凝土早期强度低的问题，而且可以在降低水泥水化热的同时，延缓混凝土早期放热峰值的出现，并使混凝土具有良好的抗渗性能。
