Abstract: The study of the characteristics of mortars is normally performed on samples prepared in laboratory and in metallic moulds with several configurations according to the standards requirements. However, the behaviour of mortar in the laboratory samples will not be exactly the same of mortar applied on real substrates.

After the application of the mortar on the substrate an interface will be formed and the interactions that occur after the contact of the mortar in the plastic state with the substrate will change over time due to hydration kinetics and absorption of substrate [1,2]. The behaviour of the mortar, over time, will then be influenced by the characteristics of the substrate and by the interface between these construction materials.

Which parameters will influence this behaviour? Will the influence of the mortars own characteristics be greater than the influence of the substrate properties?

These are some of the questions that we don’t know the answer yet and that we intend to answer with the research that is taking place at the University of Coimbra in collaboration with the University of Porto and LNEC. The first results obtained will be presented in this paper.
