    The chemical and mechanical effects of calcium carbonate

    Jan 01, 2021 The effect of calcium carbonate precipitation in cement-based materials on the residual mechanical behaviour. The evolution of CCP in cement-based materials is dominated by pH, the concentration of dissolved CO 2 (Georget et al., 2018), and the configuration of pH and CO 2 determines the process of chemical degradation. Specifically, the acid ...

    PDF New Calcium Carbonate Based Cements for Bone

    The carbonate content in the carbonated apatite of the type B cement depended on the proportion of calcium phosphate in the initial solid phase: the CO 3 2content was around 10 % (w/w) for a cement prepared with 57 % (w/w) of DCPD and L/S=1. Scanning electron microscopy (see Fig. 2) showed that the resulting cements were microporous.
