Abstract

Cementitious composites are capable of real-time monitoring of structural health, which can be used to continuously evaluate the structural condition and predict structural life. This research focused on studying the piezoresistive properties of cementitious composites by using various conductive fillers and their combinations. 3D printing was introduced to improve the fabrication method for self-sensing cementitious composites. Composites with optimal hybridization were developed for 3Dprinting. The 3D printed cementitious composites with hybrid CF and ACP achieve a FCR of 45%, which also exhibit damage sensing capabilities in large concrete beams.
