Electric Percolation of Mortars with Additions of Carbon Fiber and Graphite Powders

In this research, the effect of the addition of carbon fiber (FC) and graphite powder (GP) in a mortar with recycled aggregate was evaluated to know the percolation threshold with a water / cement ratio 0.6, sand / cement 1, PG / cement 0.5,1 and 0.1,0.3,0.5,1,1.5% of FC by weight of cement, the det...

Description
Summary:In this research, the effect of the addition of carbon fiber (FC) and graphite powder (GP) in a mortar with recycled aggregate was evaluated to know the percolation threshold with a water / cement ratio 0.6, sand / cement 1, PG / cement 0.5,1 and 0.1,0.3,0.5,1,1.5% of FC by weight of cement, the determination of the electrical conductivity of the mortar was carried out by the four-point method, obtaining the threshold of percolation from 0.3% FC by weight of cement for percentages greater than 0.5% the conductivity remains approximately constant, the increases in electrical conductivity are defined by the contact between the FC and the PG simultaneously, forming conductive routes with higher performance in their electric conductivity.
