Air permeability test that is translated to Specific Surface of the cement particles in m. 2 /g or cm. 2 /g. “Soundness Test” - refers to the ability of a hardened cement paste to retain its volume after setting without delayed destructive expansion. High steam-pressure accelerates hydration of magnesia and lime causing expansion.
