It is well known that moisture condition of concrete is one of the factor that influence on compressive strength of the concrete and velocity of ultrasonic wave through the concrete. However the influence of the moisture condition on the above properties was not discussed sufficiently. In this study, a new method based on moisture condition by using pulsed electromagnetic force acoustic method was investigated to estimate the compressive strength of concrete. As a result, it was found that the linear equation using the acoustic velocity measured by the pulsed electromagnetic force acoustic method and moisture content shows high estimation accuracy.
