Carbon nanofiber embedded cement composites: Properties and promises as sensor – A review

摘要: Abstract Modification of conventional concrete materials with nanomaterials was commenced over decades to enhance their properties. However, a novel approach is the modification electromechanical characteristics cement composite transform into cement-based sensor. These sensors have widespread implementations in performance measurement structural components such as traffic pavements, beams, columns, etc. The most desirable material increase conductivity considered be carbon nanofiber. self-sensing potential nanofiber when crack or deformation occurs has been discussed this paper. purpose review explore properties an embedded that transforms With support SEM investigations, analysis also presents various causes behind characteristics. From comprehensive examination, it established that, due its high conductivity, provides self-monitoring behavior. A hybrid combination other will improve more than alone. not only detects growth micro-cracks, but helps retain compactness. Carbon nanofibers resist micro-cracks and yield higher strength, youngs modulus, better resistance fatigue ductility. Besides, excess nanoparticles result increased porosity. Thus, optimum content essential for used Structural Health Monitoring.
