Rebound Hammer Test: An Investigation into Its Reliability in Applications on Concrete Structures

<div>Calibration curve for different distances of the test location from free edges. Dash-dotted line: in the middle of the element; continuous and dashed line: close to the free edges; dotted bold line: Schmidt curve. Calibration curve: R<sub>c</sub> = <i>e</i><sup><i>a</i>RI</sup>; RI = rebound index; <i>a</i> ∈ [0.87, 0.89]; <i>R</i><sup>2</sup>∈ [0.66, 0.84]. Inside any dataset, C.o.V. ≤ 9%.</div>
