Abstract
Uniaxial compression of carbon fiber-reinforced cement pastes in the elasti c regime caused reversible decreases in both longitudinal and transverse el ectrical resistivities. Ln contrast, uniaxial tension had been previously r eported to cause reversible increases in both resistivities. The fractional change in resistivity per unit strain is higher in magnitude for carbon fi ber silica fume cement paste than carbon fiber latex cement paste. (C) 2001 Elsevier Science Ltd.
