The new CASH+ core sublattice solid solution model of calcium-silicate-hydrate (C-S-H) can describe calcium uptake, solubility, water content, and mean silicate chain length up to 90 °C. In this study, the has been consistently extended equilibrium uptake alkalis (Li, Na, K, Rb, Cs) alkaline earths (Mg, Sr, Ba, Ra). endmembers for each cation were defined, their properties, along with binary in...
