Abstract(s) :

(Anglais) The purpose of this program is to get a better understanding of the behaviour of historical and contemporary mortars. The objective is the improvement of the restoration habits, which could be usefully re-oriented in order to upgrade practices on the restoration sites and to ensure the permanence of heritage monuments. Mortar samples from buildings and vestiges of all periods from all over the Walloon Region (Belgium) have been collected to determine their physico-mechanical properties in order to compare them with those of contemporary mortars. A global methodology has been developed to characterize the mortars based on physical properties (porosity, density, ultrasonic velocity) and strength properties. The strength properties characterization has performed by doing scratching and micro-drilling tests. With the physico-mechanical characterization methodology, our research program has the most precise and the most rigorous mechanical evaluation of very small samples of historical mortars.
