Objectives of Non-Destructive Testing

Estimating compressive strength at the site. Estimating uniformity and homogeneity. Estimated quality in relation to the standard requirement. Identification of areas of lesser integrity compared to other parts. Detection of cracks, voids, and other imperfections. Monitor changes in the concrete structure that may occur over time. Identification of the reinforcement profile and measurement of the cover, bar diameter, etc. Condition of prestressing / reinforcing steel with respect to corrosion. Content of chlorides, sulfates, alkalis or degree of carbonation. Measurement of the elastic modulus. Grouting condition in prestressing ducts. Read more
