Cement Science and Technology
Fundamental studies are being
undertaken to characterise the morphology, composition, physical and
mineralogical nature of Portland and non-Portland cements and combinations.
This research is at the forefront for the use of Portland cement in ternary and
poly-phase blends with industrial by-products. In particular, the work
concentrates on the application of pulverized-fuel ash (PFA), ground granulated
blast furnace slag (GGBS), condensed silica fume (CSF), metakaolin (MK) and
limestone powder. Investigations are establishing understanding of how to use
these materials to control heat of hydrated dimensional stability and hydrate
microstructure through calorimetry, thermal analysis and other advanced
techniques.
