Soundness refers to the ability of cement to not shrink upon hardening. Good quality cement retains its volume after setting without delayed expansion, which is caused by excessive free lime and magnesia. Tests: Unsoundness of cement may appear after several years, so tests for ensuring soundness must be able to determine that potential.
