Webbcement slurry. During the setting phase of the cement, the cement builds up gel strength and the mechanism that allows gas to invade the cement matrix is the gel strength development of the slurry as it changes from liquid to solid. The hydrostatic head of the cement column may thus be reduced down to that of the mix water. This may be Webb15 maj 1999 · An acoustic method and system for determining the static gel strength of a cement slurry sample has been developed that provides nearly continuous, accurate, non-mechanical measurements of the static gel strength of cement slurry samples.
