Effect of Different Micro Metal Powders on the Electrical Resistivity of Cementitious Composites

“

he electrical resistivity is an essential parameter describing materials' capacity to convey electric current. Normal cementitious materials display a high estimation of the electrical resistivity because of their insulating nature. However, the high electrical resistivity of concrete can be reduced by a sufficient amount of electrically conductive admixture. Such an improvement is advantageous in self-sensing or self-heating concrete design. In this study, the effects of metal additives on the electrical resistivity of hardening cement paste were investigated.
