Self-Sensing Properties of Different Carbon Nanomaterial Based Composites for Sustainable Infrastructures

Abstract

Recently, various studies have focused on the cement-based composites doped with carbon-based materials to provide non-structural functional properties without compromising engineering properties. Some of the most important non-structural functional properties are self-sensing performance of cement-based composites, such as damage, strain, structural vibration, and durability monitoring. Generally, the term attained as “self-sensing” is related to the function of cement-based material to exhibit its piezoresistive ability. Accordingly, self-sensing capability of the cement-based composites can be attained and structural or/and material health monitoring can be provided without the need external integrated. In this study, the mixtures of cement-based composites functionalized with self-sensing ability was addressed. The paper focuses on the production techniques, engineering performance and multifunctionality properties of small-size specimens to large-scale trial specimens. Challenges of the current methods as sensory materials are also discussed together with other cement-free composites. © 2022 Altuntas et al.
