ANALYSIS OF THE HYDRATION PROCESS OF CEM II/B-M COMPOSITE CEMENT

This paper presents the hydration kinetics of a CEM II/B-M type Portland composite cement by DTA/TGA analyses and mathematical and software modeling prediction. The reason for this choice is generated by its use as the main binder in the concrete matrix used for radioactive waste conditioning processes and the lack of public information related to its hydration process. The comparison between the experimental and modeling results indicated a good agreement and correlation of the results, reinforcing the idea that modeling can be a powerful tool that can be used in understanding this complex multicomponent-multiphase system of hydrated cement and can facilitate the assessment of the geochemical evolution of cement-based materials under different environmental conditions.
