Hydrogen-bond dynamics of water in C-S-H, the binding phase of Portland cement

Abstract: During the setting process of Portland cement, different mineral hydrates nucleate and grow, of which calcium silicate hydrate (C-S-H) is the most important binding phase. It is generally accepted that the poorly crystalline structure of C-S-H has layered disordered structure. Molecular modelling studies have reported the presence of confined water in the interlayer space and the external surfaces of C-S-H platelets. Despite these modelling advances, an experimental description of the water structure, dynamics and energetics within the different pores of C-S-H is still lacking. This proposal aims to elucidate the H-bond dynamics of water in C-S-H, using a well constrained synthesis protocol that allows accessing the different pores of the C-S-H structure. This study will be key to construct a complete picture of water structure and dynamics in the different pores of C-S-H.
