Thin film display technology using light-emitting polymers


The use of display panels and monitors has grown enormously in recent years in is very dangerous in the case of cement mortars, concretes and hydraulic binders in general, since two damaging expansive reactions are likely to take place in the presence of gypsum, leading to the formation of attringite and thaumasite. This research proposal aims to focus on the role of environmental pollution in the deterioration of ancient and modern hydraulic mortars (pozzolan and cement-based). An understanding of the impact of the environment on such mortar types is of great importance as the number of monuments from the 19th and 20th century that need restoration in all European countries is increasing. Understanding of future behaviour and environmental impact is of utmost importance to decide how to deal with the hydraulic mortars used in current restoration sites. Emphasise is put on the study on sulphation of hydraulic mortars due to environmental effects with the aim of clarifying

1) why cement mortars are more reactive than lime-pozzolan and lime mortars;
2) if pozzolanic mortars are affected by environmental sulphation;
3) if environmental sulphation can produce expansive cilringite;
4) if environmental sulphation and carbonation can produce thaumasite in cement and lime-pozzolan mortars;
5) what the change of porous system and the physical properties of the mortar are due to those reactions.
