Experimental evaluation of damage and stress rate in concrete during compression test using ultrasonic investigation.
Session

Description
The relationship between concrete pulse velocity and compressive stress at various levels was explored. Under compression, the UPV and damage measured showed that the UPV curve has a stable trend until 60% of the ultimate stress, a declining trend begins until failure occurs. This trend may be used to replicate the progression of the concrete's damage curve. The applied load causes matrix microcracks, which is the major source of the increase in concrete specimen damage. Failure is caused by the instability and penetration of the macrocracks. The data from each test was examined to predict strength using Ultrasonic Pulse Velocity and compared to the experimental strength measured and determined. Eurocode was used to create empirical relationships between concrete compression strength and strain module. It was determined that indirect, non-destructive concrete testing may be evaluated using lost cost. The stress state and damage can be assessed by the loss of UPV.
