The grey colour of ordinary Portland cement is due to the presence of ferrite, the presence of which is unwelcome in White Portland cement (WPC)

Hydration of the two calcium silicate clinker phases, C3S and C2S proceeds, after an initial induction period, to form a poorly-defined calcium silicate hydrate

Cement powders contain four major hydraulic constituents, ie clinker phases, which hydrate at different rates and thus influence important factors such as setting time, workability and mechanical strength

Raman microscopy allows us to understand the early stages of oilwell cement hydration, which is crucial to its application

In collaboration with the Instituto de Cienncia y Tecnologia de Polimeros (Madrid) we have examined the extent of the surface modification of a polymeric membrane. The polymer (PVC) was modified according to the following reaction scheme

The objective of this project is to bind sand grains together whilst maintaining formation porosity and fluid flow
