Understanding imbibition in cementitious materials including C-S-H strain measurement and geometric restriction

Maya Nicole Harris

Cementitious materials show anomalous behaviour during capillary imbibition: a lack of linearity of the mass gain versus the square root of time. This is considered to be caused by the water retention in the calcium silicate (C-S-H) structure (and conseque ...

A method for the reliable and reproducible precipitation of phase pure high Ca/Si ratio (>1.5) synthetic calcium silicate hydrates (C-S-H)

Paul Bowen, Karen Scrivener, Maya Nicole Harris, Grace Simpson

Various methods have been developed to synthesize C-S-H; however, these methods have only allowed for the successful production of pure-phase C-S-H with Ca:Si of 1.5 or less. Attempts to form higher Ca:Si ratios by these methods gives C-S-H (Ca:Si 1.5 or l ...

Precipitation, Characterization, Kinetic, and Thermodynamic Modelling of Synthetic C-S-H Systems (C-S-H, CASH, CSH+$)

Maya Nicole Harris

This thesis investigates the effects of aluminates, sulfates, and heterogeneous substrates on the nucleation and growth of synthetic calcium-silicate-hydrates (C-S-H) produced by dropwise precipitation. The use of synthetic C-S-H, separate from other cemen ...

The Atomic-Level Structure of Cementitious Calcium Aluminate Silicate Hydrate

Paul Bowen, Karen Scrivener, Aslam Kunhi Mohamed, Jirawan Siramanont, David Lyndon Emsley, Brennan James Walder, Maya Nicole Harris, Pierrick Berruyer, Pinelopi Moutzouri, Mattia Negroni

Despite use of blended cements containing significant amounts of aluminum for over 30 years, the structural nature of aluminum in the main hydration product, calcium aluminate silicate hydrate (C-A-S-H), remains elusive. Using first-principles calculations ...
