Resumen

Non-Destructive Testing (NDT) were applied to evaluate the quality of concrete and steel bars in reinforced concrete bridges. Steel bars diameter, compressive strength and ultra-sonic wave speed were evaluated in structural elements such as columns, pillars, concrete walls and slabs, by using the Profometer A630, Original Schmidt Rebound Hammer and Pundit PL-200 equipment in two reinforced concrete bridges. The concrete had a targeted rebound number of 27.1 to 48.6, a predicted compressive strength of 11 MPa to 47 MPa, a concrete thickness of 15 mm to 62 mm, steel bars diameter of 12.5 mm to 38.1 mm, and ultrasonic wave velocity of 2064 m/s to 4266 m/s. Structural elements were evaluated according to the construction standard codes.
