The use of confocal raman microspectroscopy in depth profiling polymer films
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
Raman spectroscopy of White Portland cement
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)
Raman spectroscopy of pure clinker phases
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 spectroscopy of cement - Hydration of pure clinkers
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
Raman spectroscopy of cement - Pure synthetic C-S-H
A series of synthetic C-S-H phases has been prepared, with the aim of studying structural changes with changes in C/S
Accelerated Environmental Corrosion Tests
MERI has facilities available for humidity testing and neutral salt spray testing to ASTM Standard B117
Life cycle asset management
An overview of our research into life cycle asset management
Raman spectroscopy and ESEM images of Class G oilwell cement
Raman microscopy allows us to understand the early stages of oilwell cement hydration, which is crucial to its application
Metals and Metallic Coatings
Corrosion tests can be performed on metals, alloys and metallic coatings, such as hot-dip and electroplated surfaces
