Detalhes bibliográficos
Resumo:In order to study the damage after concrete cracking, the influence of the combined use of steel fiber and carbon fiber on the conductivity and crack resistance of concrete beam under flexural loading were investigated. Carbon fiber and steel fiber were added as diphasic conductive materials to produce the electric conductive and ductile concrete. This paper reports the experimental and analytical work associated with establishing the crack width in relation to the fractional change in resistance of electric conductive concrete. After cracking, the electrical resistance change was found to correlate linearly with the crack width on the tension side of concrete beam.
