The dissolution of C3S in water over time. (A) The experimental silicon and calcium concentration and the fitted values obtained using Eq. 1. (B) The fitted dissolution rate is calculated using Eq. 2. The initial dissolution rate is estimated when less than 0.01% of the solid is dissolved. (C) The initial dissolution rate normalized to the specific surface area (SSA) measured by BET or the estimated geometric surface area (GSA), compared to data from Nicoleau et al. .
