Rather than other methods, NDT is more suitable and practical to be performed in order to detect flaws and deterioration in concrete structures. This paper provides a review by studying various research works on concrete by performing ultrasonic technique NDT. In particular, the working principle of ultrasonic NDT, type of sensor and techniques adopted in ultrasonic NDT are briefly described in this paper. Further research based on preliminary data will be conducted to improve previous experimental work.enNon-destructive test, concrete structure, ultrasonic tomographyArticle1741
