Determination of the electrical conductivity of heat-resistant concretes

The problem of the electrical conductivity of heat-resistant concretes and bonding agents is considered and a method for determining this parameter is suggested. In addition to the thermal resistivity, the electric conductivity is a factor affecting the lifetime of lining materials for high-temperature devices. The problem is especially urgent in electric heaters. Translated from Ogneupory, No. 7, pp. 25–26, July, 1994.
