Fig 4. Mineralisation kinetics.

Experimental mineralisation kinetics from Ref. [47] (dashed) together with two exponential fits of the form $m_{\text{max}}-(m_{\text{max}}-m_{\text{f}}){\mathrm{e}}^{-k_{\text{m}}t}$ (solid lines). The short-time fit has m_f = 3 Ca wt%, m_max = 20.1 Ca wt%, k_m = 0.0194/day (also shown in the inset). The long-time fit has m_f = 21.85 Ca wt%, m_max = 30.4 Ca wt%, k_m = 9.3 · 10^-5/day.
