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. | Apstrakt
U okviru ovog rada dati su rezultati ispitivanja brzina prostiranja ultrazvučnih talasa u betonskoj konstrukciji – nedestruktivna metoda – in situ u cilju uvida u kvalitet betona koji je ugrađen u telo brane Durutovići za potrebe rudnika uglja Pljevlja. Merenjem brzine prostiranja ultrazvučnog talasa definisaće se sledeći parametri: homogenost betona, prisustvo praznina, pukotina i drugih nedostataka u betonu kao i kvalitet betona vezan za njegovu čvrstoću. |
| Keywords: concrete, concrete quality, spreading speed of waves, ultrasound waves | Ključne reči: beton, kvalitet betona, brzina prostiranja talasa, ultrazvučni talasi |
