Abstract
Ultra-high performance concrete (UHPC) has the inherent potential to self-sensing capability due to its inclusion of steel fibers or other electrically conductive materials. Many studies have investigated the electrical and piezoresistive properties of UHPC. With the incorporation of micro steel fibers, carbon nanotubes, carbon nanofibrils, or nano graphite platelets, it opens up great potential to allow UHPC to effectively sense stress, strain, and crack damage. Therefore, the UHPC-based structures can achieve the functionality of structure health monitoring (SHM). This article reviews the recent advances in self-sensing capability of various UHPC-based materials with the focus on sensing capability and mechanisms. Future applications and challenges are also discussed.
Highlights
Frontiers in MaterialsReview of Self-sensing Capability of Ultra-high Performance Concrete
Ultra-high performance concrete (UHPC) has gained increasing attention during the last two decades (Schmidt and Fehling, 2005; Batoz and Behloul, 2011; Gowda and Das, 2017; Xue et al, 2020)
Another interesting finding was the equivalent circuits analysis demonstrated that the curing age has greater influence than incorporation of fibers on electrical resistivity, meaning at later age (28 days) cement matrix and pore solution are more dominate than metal fibers in term of conductive mechanism of UHPC
