This document compares destructive and non-destructive testing methods for concrete in Sudan. Two concrete grades (25 MPa and 30 MPa) were tested using crushing tests, tensile tests, rebound hammer tests, and ultrasonic pulse velocity tests at various ages. Crushing tests produced the most accurate strength results when compared to the designated strengths, while rebound hammer tests initially overestimated strengths. Non-destructive tests were more sensitive to variations but provided reasonable strength estimates over time. Destructive tests were concluded to produce more logical results consistent with known concrete behavior.
