Co-grinding significance for calcium carbonate-calcium phosphate mixed cement. Part II: effect on cement properties

In the present study, we aim to evaluate the contribution of the co-grinding process in controlling calcium carbonate-dicalcium phosphate dihydrate cement properties. We set a method designed to evaluate phase separation, usually occurring during paste extrusion, which is quantitative, reliable, and discriminating and points out the determining role of cogrinding to limit filter-pressing. We show that solid phase co-grinding leads to synergistic positive effects on cement injectability, mechanical properties, and radio-opacity. It allows maintaining a low (
