Triana Camacho a , Andrea Meoni a , Filippo Ubertini a a University of Perugia, Depart,ment of Civil and Environmental Engineering, Via G. Duranti, 93 06125 Perugia (PG) Italy Abstract This study delves into the potential of self-monitoring masonry components constructed with specialized mortars containing conductive carbon-based fillers. The primary objective is to assess their ability to autonomously evaluate their structural integrity. These innovative masonry elements are designed to produce an integrated monitoring system within a structure. This system can effectively identify and respond to changes in structural performance, such as partial damage, crack propagation due to structural anomalies, or extreme loading events. The key to this self-monitoring capacity lies in the application of sensing mortars. These mortars can be used as the bedding material for masonry blocks. Through this approach, the study aims to preliminary characterize and explore the feasibility of cement-based smart mortars for intelligent masonry structures, aiming at diagnosing their own condition. Electromechanical tests on single components and more complex, though small scale, masonry elements allowed to achieve a first optimization of the materials and the building procedure, and to achieve a preliminary characterization of the mechanical, electrical and sensing behaviour. Compressive and bending tests have been coupled to electrical measurements through electrodes applied in the samples. The results of the work demonstrate the potential of the technology to be scaled to larger-scale structures. © 2024 The Authors. Published by ELSEVIER B.V.
