Objectives:

This project has two objectives:

  • To optimise growth conditions (particularly minimising supersaturation requirement) of hydrates in order to produce a range of materials with different and carefully controlled oxide composition including water content;
  • To provide characterisations of these materials by conventional methods including X-ray diffraction, scanning electron microscopy, 29Si high resolution MAS NMR and differential scanning calorimetry.

Expected Results:

  • Month 12: To produce C-S-H samples as a function of CaO to SiO2;
  • Month 21: To provide conventional characterisa- tions of the C-S-H materials;
  • Month 30: To make hydrates with other, well controlled, oxide compositions including with added AlO2, MgO and SO3;
  • Month 39: To provide conventional characterisations of the these materials.

Planned Secondments

  • 1 month at UNIBO: Participation in 1H NMR analyses; start month 10
  • 4 months at HTC: Characterisation of hydrate shrinkage in an industrial environment; start month 27
