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)

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

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

The project involved the development of a nitriding process to work at low pressures, achieving high plasma densities and degree of activation of nitrogen

This project seeks to gain fundamental understanding of the oxidation process of TiN, TiAlN and TiAlCrYN based hard coatings at elevated temperatures, in the range of 700-950 degrees celsius

Nowadays, coatings with good wear and corrosion resistance consist in high thickness Ni or hard Cr coatings from electrochemical processes

The increasing demand for sustainable paper-based packaging is driving research towards developing renewable coating materials with high barrier properties against gas, water vapour and odours

This project is concerned with development of a duplex coating system for steels, bringing together two separate surface treatments in an entirely novel and synergistic way

The DTI-Link Surface Engineering project 'Multicoat' was initiated in June 1995 to research and develop industrial scale structured PVD hard coatings

This project is concerned with development of coating systems, steels and tool geometries with particular suitability for the machining of titanium and aluminium based alloys
