    The Effects Of Seawater On The Hydration Microstructure

    Mar 04, 2019 This contribution investigates the effects of seawater and colloidal silica NS in the amounts of 1, 3 and 5 wt, respectively, on the hydration, strength development and microstructural properties of Portland cement pastes. The data reveal that seawater has an accelerating effect on cement hydration and thus a significant contribution to early strength development was observed.

    More studies, especially some long-term studies comparing MTA and Portland cement, are necessary. Conclusion The existing literature gives a solid base for clinical studies with Portland cement in order to replace MTA as an endodontic material. Portland cement could be a substitute for most endodontic materials used in primary teeth.

    Clay Cutans And The Origin Of Illite Rim Cement An

    The more iron oxide in the cutans, the less authigenic illite formed. The illite rim cement precipitated after mechanical compaction, and is probably related to illitization of smectitic clay in the cutans. Illite rim cement is thus related to the local paleogeography of the basin, including aridisol development and erosion of such soils.
