“…Electrical measurement is a method of nondestructive evaluation. It can be in the form of electrical resistance measurement, as the resistance is changed upon damage (Prabhakaran, 1990;Muto et al, 1992Muto et al, , 1995Schulte, 1993;Kaddour et al, 1994;Sugita et al, 1995;Todoroki et al, 1995;Ceysson et al, 1996;Irving and Thiagarajan, 1998;Wang et al, 1998a, b;Abry et al, 1999Abry et al, , 2001Chu and Yum, 2001;Kupke et al, 2001;Wang et al, 2001;Mei et al, 2002;Wang and Chung, 2002;Chung and Wang, 2003;Wang et al, 2004;Yoshitake et al, 2004). As a consequence, the change in resistance provides an indication of the extent of damage.…”

The electric potential method, which involves measuring the potential at a distance from the line of current application, is effective for damage sensing of carbon fiber polymer-matrix composites when the distance is sufficiently small, such as 1.0 mm (8 laminae) in the through-thickness direction. It is ineffective when this distance is 2.1 mm (16 laminae). The electrical resistance method, which involves measuring the potential on the line of current application, has no thickness limitation. However, it suffers from current path distortion upon damage and the consequent reduced sensitivity for damage. A minor phenomenon of the measured resistance decreasing with increasing damage is observed for the regions of the composite not containing the point of impact. The major phenomenon of the resistance increasing with damage overshadows this minor phenomenon for the region containing the point of impact.

Cement-based materials that exhibit piezoresistivity with sufficient magnitude and reversibility contain electrically conductive fibers. The phenomenon allows the materials to sense their own strain. The fibers are preferably discontinuous. Carbon fibers (15 mm diameter) are most effective. Steel fibers (8 mm diameter) are less effective. Carbon filaments (0.1 mm diameter) are ineffective. The piezoresistive behavior, mechanism and materials are reviewed, including cement-based materials with continuous and discontinuous fibers.

Carbon-based nanomaterials are used in various industrial fields because of their excellent performance. In construction, cementitious composites containing carbon-based materials have the potential to be used for various purposes such as crack detection and deicing. However, carbon-based materials have been experienced difficulties that cannot be easily dispersed in the cementitious composite because of the inherent material characteristic. This study aimed to investigate the possibility of using these carbon-based nanomaterials as construction materials. The structural and electrical performances of cementitious composites were investigated based on carbon-based materials such as Multi-Walled Carbon Nanotube (MWCNT), Single-Walled Carbon Nanotube (SWCNT), Graphene Nanoplatelets (GNP), Conductive Graphite Powder (CGP). In addition, the microstructural analysis was performed through the noncovalent functionalization of carbon-based nanomaterials to examine the dispersibility.
