  • Method and apparatus for measuring properties of concrete
    Publication number: 20050210995
    Abstract: Methods and apparatus using time domain reflectometry to determine electrical properties of concrete for calculating physical and mechanical properties of the concrete that are indicative of concrete quality and durability. The dielectric constant of a concrete is determined to calculate the gravimetric water content of the concrete for use in finding the water-cement ratio of the concrete. Electrical conductivity of curing concrete is determined to calculate compressive strength of the concrete for use in predicting strength development in the concrete.
