Abstract

Thermodynamic modeling is essential for our understanding of chemical reactions. With the three most important variables influencing temperature, pressure and chemical composition, we can predict if the reaction will take place and the final state after the reaction is over. The general laws governing thermodynamics have been known for a long time and were first applied to cement chemistry in the late 19th century by Le Chatelier to prove that cement hydration was obtained. The clinker's initial solubility leads to an always saturated water phase for the hydration reaction thus leading to the precipitation of solid phases. Thermodynamic model was developed and applied by geochemists to calculate the system of complex reaction often occurring in nature using cementitious materials such as soil stabilization, concrete/soil interaction, concrete corrosion, cement hydration, radioactive waste disposal. Therefore the basic theories of thermodynamic modeling and its application are presented in this paper.
