ESR: Rémi Albert Kogon


Start date: February 1, 2018


This project has two objectives:

  • To make measurements of 1H NMR relaxation at early hydration times (0.1 to 6 hours) in order to confirm or otherwise the Gartner model of early stage hydration and the emergence of gel pores from the stacking (“zipping-up”) of Gartner sheets;
  • To use, refine and set limits on the 1H NMR analysis used to characterise C-S-H for the characterisation of hydrates with other oxide mixes made in Project 1.

Progress of the project

Expected Results:

  • Month 12: Very early age NMR measurements of standard C-S-H hydration;
  • Month 21: NMR measurements as a function of CaO to SiO2 ratio & interpretation in terms of Gartner model;
  • Month 30: NMR measurements of other oxide mixes;
  • Month 39: Limits of NMR method established.

Planned Secondments

  • 4 months at HTC: Characterisation of hydrate porosity in an industrial environment; start month 27.
  • 2 months at MR Solutions: Application Scientist: NMR of dental hydrates; start month 31.
