What is the compatibility between cement and admixture?

The compatibility between cement and admixture is also called adaptability. The same admixture has different effects on different cements. Good performance is called good compatibility, and poor performance is called poor compatibility. When cement with poor compatibility meets admixture, it needs to be adjusted by other means to make it compatible. This is a common problem in the actual combat of additives, and it is also the basic skill of technicians.
