Correlation of parameters describing microstructure of hardened cement slurry for the purpose of increasing tightness of cement mantle

The results of laboratory experiments on fresh cement slurries are presented in this paper. The samples of hardened cement slurry were hydrated for 28 days in wellbore-like conditions and then analyzed for parameters describing their microstructure. The obtained results created a basis for a correlation analysis of parameters of microstructure of hardened cement slurries. The dependences having the big-gest effect on increasing the tightness of the cement mantle were also addressed to.
