Influence of limestone on the hydration of Portland cements
TL;DR: In this paper, the influence of the presence of limestone on the hydration of Portland cement was investigated, and it was shown that the stabilisation of monocarbonate in the absence of limestone indirectly stabilised ettringite, leading to a corresponding increase of the total volume of the hydrate phase and a decrease of porosity.

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.
