It reflects the uniformity of cement volume change during the coagulation and hardening process. Cement stability can be determined by the test cake method. The volume stability is characterized by observing the changes in the appearance of the cement standard consistency pure paste test cake after boiling. In order to determine the cement stability in the plateau environment, a plateau cement stability test boiling device is required.
