Abstract
Low-cost controlled electrical resistivity materials based on Portland ceme nt and exhibiting low values of the relative dielectric constant have been attained. The materials are cement paste containing short electrically-cond ucting fibers. With steel fibers (0.1 vol.%), the resistivity and relative dielectric constant (10 kHz) are 8 x 10(4) Omega .cm and 20, respectively. With carbon fibers (1.0 vol.%) and silica fume, these quantities are 8 x 10 (2) Omega .cm and 49, respectively.
