Abstract
Electrical conductivity measurements were made on concrete systems containing blast-furnace slag. It was found that the slag content significantly influenced the concrete conductivity. A linear relationship between the concrete conductivity and the slag content and the volume fraction of aggregate was established by experiment. The relationship can be expressed as follows s_c = k_a·f_a + k_s·(νslg&den;c) + k_owhere s_c is the concrete conductivity; f_a is the volumetric fraction of aggregate; (slg/c) is the relative content of slag by weight of cementitious materials; and k_a, k_s, and k_o are empirical coefficients. This relationship provides a basis for the determination of slag content in hardened concrete by electrical conductivity methods.
