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

<div>Calibration curve for dry and saturated cubes. Continuous line: dry cubes; dashed line: saturated cubes; dotted bold: Schmidt curve. Calibration curve: <i>R</i><sub>c</sub> = <i>e</i><sup><i>a</i>RI</sup>; RI = rebound index; <i>a</i>∈[0.11, 0.12]; <i>R</i><sup>2</sup> = 0.91. Inside any dataset, C.o.V. ≤ 9%, dry; C.o.V. ≤ 12%, saturated.</div>
