Thermodynamic modeling of the essential

2018-7-3  The chloride transport properties of cement-based materials are determined via the physicochemical interactions between the pore solution and the cement hydrates. Herein, a thermodynamic model based on surface complexation reactions and dissolution/precipitation reactions was established to investigate the essential physicochemical interactions.

2020-12-8  In the presence of significant quantities of carbon dioxide (CO 2 ) and elevated temperatures in the atmosphere due to climate change, cement-based materials are susceptible to carbonation. Blended cements are more prone to carbonation attack than Portland cement. There is a need to evaluate the carbonation resistance of blended cements in a carbonation-prone environment.
