Thermodynamic Modelling of the Effect of Temperature on the Hydration and Porosity of Portland Cement
TL;DR: In this article, the phase assemblage and pore solution of Portland cements hydrated between 0-60°C were modeled as a function of time and temperature, and a good correlation between calculated porosity and measured compressive strength was observed.
