Cement and accelerator compatibility is critical for achieving proper mechanical performance in sprayed matrices. Few studies in the literature focus on establishing relationships between accelerated chemical reactions and the resulting mechanical properties of these matrices. The objective of this study is to evaluate the correlation between the chemical processes occurring in accelerated matrices...
The objective of this work is to parametrize the early age hydration behavior of accelerated cement pastes based on the chemical properties of cement and accelerators. Eight cements, three alkali-free and one alkaline accelerators were evaluated. Isothermal calorimetry, in situ XRD and SEM imaging were performed to characterize kinetics and mechanisms of hydration and the microstructure development...
