Determination of the density of concrete by ultrasonic velocity

Abstract

This article discusses the issue of determining the density of concrete using the ultrasonic method of testing concrete structures. The article discusses traditional methods for determining the density of concrete from selected samples and using radioisotopes. The advantages and disadvantages of these methods are highlighted. The authors proposed the use of an ultrasonic method for determining the density of concrete. From the equations of the propagation velocity of ultrasonic waves in solid media, the density of the material is expressed for the case of transverse and longitudinal waves. The authors proposed to use the derived equations to determine the density of concrete during ultrasonic testing of concrete and reinforced concrete structures. The authors provide explanations for determining the parameters of concrete included in the equations. The factors that influence the determination of the ultrasound velocity are given. Using the proposed formulas, you can calculate the density of concrete structures.
