Hydration process of cement takes place once it is mixed with water, forming set cement gradually. The hydration process will last for quite a long time after setting. During the hydration process, cement hydrate, internal pore structure, apparent volume, and its mechanical performance still keep changing. The performance of set cement is also affected by the changing conditions caused by the subsequent projects or development operations, so it is important to research into the long-term performance of set cement and take some measures to improve cementing job quality.
