Development of Self-Sensing Cement Composite Using Nanomaterials for Structural Health Monitoring of Concrete Columns – A Comprehensive Review

Abstract. Due to age, structural deterioration, and other factors, concrete constructions such as beams columns will inevitably deteriorate. The growth of nanomaterials recent advances in multidisciplinary research has broadened cement composites' applicability various fields. A self-sensing composite can detect its own deformation, strain, stress by changing electrical characteristics, which may be measured with resistivity. Carbon-based nanomaterials, carbon fiber, black, nanotube, have a strong potential increase composite's mechanical (strength) (resistivity, sensitivity) potentials due their remarkable strength conductivity. the artificial integration conductive carbon-based components generate piezoresistive properties typical composites, transforming them into composites. As result, review focuses primarily on development nanoparticle-based composites use health monitoring columns. This critically examines materials used, fabrication techniques, strength, sensing methodologies used develop composite. difficulties commercializing well solutions, are also highlighted. According review, difference Poisson ratio youngs modulus between leads different conductivity before after embedding study, addition material diminishes workability large specific surface area. Because well-distributed network, resistivity is significantly lowered. study shows that inclusion no bearing capacity influence column. Finally, according ability monitor
