“…Expanded Uncertainty (U) [4,15,16] The most important aspect of ultrasonic pulse velocity tester is the time measurement, in this study it is observed that in case of uncertainty in time measurement is affected by repeatability transit time measurements, calibration and resolution of instrument. Influence of these parameters is shown in Figure 7.…”

“…Several measurements are taken on the instrument in a continuous fashion without re-calibration, which can lead to considerable temperature-related uncertainties. The density and Young's modulus of test specimen changes with change in temperature, thus a theoretical calculation can be employed to calculate the wave velocity for a wide range of temperatures (13)(14)(15)(16)(17)(18) . https://www.indjst.org/…”

Background: In construction field, to check the quality of the developed concrete, material testing methods plays a very vital role. As the testing gives measurements therefore maintaining the accuracy and precision of measurement is very essential for producing higher quality concrete. But always uncertainties in measurement is inevitable in every measurement. Methods: The effects of qualitative factors which contributes in uncertainty are considered largely in case of measuring instrument but very less attention is given on impact of these parameters on test specimen. It is necessary to integrate both the instrument and test specimen related parameters to get satisfactory results. This paper focuses on the measurement uncertainty calculation in dynamics Young's modules of elasticity obtained from ultrasonic pulse velocity tester. Findings: In most of the studies on non-destructive methods propagation of uncertainty is largely dependent on repeatability of measurement results, but we need to focus on all parameters associated with particular measurement process which may contribute in final uncertainty value. To evaluate the measurement uncertainty of dynamic young's modules of elasticity, two major factors are considered one is uncertainty in velocity and another is uncertainty of density. Novelty: The calculation of uncertainty in velocity is calculated from the measurement of uncertainties from time (ultrasonic pulse velocity test) and phase length of concrete block. Whereas the uncertainty of density is done from the calculation of uncertainty with mass and volume of the concrete block.

“…Overall, the measurement result is merely known as an approximation of the measurand's value, and it is only completed after combining the uncertainty with final obtained result. This is because all measurements are subject to the errors, it is adequately and frequently claimed that a measurement result outcome is only complete if it is accompanied by a quantitative description of its uncertainty (3,4) . Measurement uncertainty also describes how genuinely the true value of the measur and is known, assuming that no undiscovered systematic errors are impacted by the measurement.…”

Objective:The major objective of the proposed work is to determine the concrete's expected compressive strength by evaluating the consistency of concrete using Rebound Hammer Test. Further, the determination of the quality of one component of the concrete relates to the quality of another component based on the concrete meeting criteria established by the several standards in the literature. Methods: Laboratory professional's needs to properly correlate the compressive strength with the observations of rebound hammer normally called as rebound index. Since test readings are affected by number of parameters, measurement uncertainty plays vital role in deciding the output of test. Analytical method as per the guidelines of GUM (Guide to the Expression of Uncertainty in Measurement) and Monte Carlo simulation is used for obtaining uncertainty value in measurement of compressive strength. As per the proposed test procedure total 10 test blocks made up of concrete are selected for testing. For each block 6 readings are taken using rebound hammer. The rebound index (RI) obtained in reading is then converted to compressive strength (CS) value. Findings: The obtained test results are compared with the simulation values obtained from Monte Carlo simulation. The results shows that the magnitude of evaluated uncertainty values are on higher side as compare to simulated uncertainty values. Novelty and applications: In this paper uncertainty related to compressive strength measurement using rebound hammer test is evaluated by considering the effects of various parameters related to instrument, test procedure and test environment. This obtained uncertainty values provides reliable information about compressive strength of concrete structures.
