Abstract: In this paper the first results of a research project carried out to validate a Non Destructive Test (NDT) to determine the in situ mechanical characteristics of mortar in historical masonry buildings are presented. According to the compositions of historical mortars, the most commonly used in Tuscan buildings, 15 types of mortar with different mechanical characteristics were produced, obtained with 5 classes of lime (both hydraulic and hydrated) and river sand with 3 grading curves. Fifteen samples, one for each class of mortar, were obtained. Flexural and compression tests were performed on 6 of them, Drilling Resistance Measurement System (DRMS) test was applied on the other 6. DRMS is a drilling device that measures the resistance to perforation of the material being tested. During the test the resistance force to perforation is measured with continuity, maintaining rotational speed and penetration rate constant. The result is a curve that shows the drilling resistance profile. The research project is aimed at validating a correlation between the sizes measured with DRMS and the mechanical characteristics of mortar in masonry buildings.
