| dc.description.abstract | Preserving the functional performance of buildings across their lifespan
is crucial, especially when considering potential changes in use,
unforeseen natural disasters, and the inevitable effects of time.
Traditional destructive testing methods, while effective, can compromise
structural integrity and disrupt building operations. Therefore, nondestructive testing methods have emerged as valuable tools for accurately
assessing concrete condition without causing any damage. This study
investigates the effectiveness of two such methods, the hammer test and
Ultrasonic Pulse Velocity (UPV) test, in evaluating the compressive
strength of different concrete grades (K225 to K325). Sixty cubic
specimens were tested, with each grade having twelve samples to ensure
robust data analysis. Results reveal strong correlations between both
non-destructive tests and compression strength. The hammer test, with its
simplicity and ease of use, demonstrates a moderate correlation (R² =
0.5452), while the UPV test, which provides deeper insights into internal
concrete properties, exhibits a slightly lower correlation (R² = 0.0709).
Notably, a combined equation incorporating both tests yields a
significantly improved correlation (R² = 0.405), highlighting the potential
for synergistic use of these two methods. | en_US |
