Abstract

This paper presents results of the propagation velocity investigations of ultrasound waves in the concrete construction - so called non-destructive method - 'in situ' due to inspection of concrete quality that is inbuilt into the body of the Durutovići dam, built for the Pljevlja coal mine. By the velocity of ultrasound waves measures, the following parameters will be defined: concrete homogeneity, presence of gaps, cracks and other defects in concrete, as well as concrete quality related to its strength.
