Abstract
Several microwave frequencies were used to measure the dielectric and reflection properties of four cement paste samples for 27 days. Dielectric properties and reflection coefficients decreased as a function of increasing w/c. Variations in the reflection coefficient and compressive strength followed similar trend. A correlation of compressive strength and reflection coefficient was obtained.
