This is a very easy test to conduct and the rebound value is a the strength of the same concrete. This study planned to adapt the good symptom of rock characteristics and gives significant Schmidt Rebound Hammer SRH equipment and the Ultrasonic correlation with net breaking rates of rebound hammers. Pulse Velocity UPV tester to investigate the concrete structures in The non-destructive methods for evaluation of the actual site.
A combined method for the above two tests is established in compressive strength of concrete in existing structures are based order to improve the strength estimation of concrete. Regression analysis approach is used as destructive testing in All specimens for compression test were cubes of mm side Shariati et al. The compressive strength of hardened concrete was determined by using specimens The best fit line, which represents the relationship tested at 1, 3, 7, and 14 days intervals.
Two specimens were tested between the rebound number and the compressive and the averaged results for each strength test at each age were used. Readings where, R is the rebound number.
The The mean rebound number and mean strength obtained R2 value is found to be The pulse velocities are measured in direct and semi direct method between opposite faces Ultrasonic Pulse Velocity UPV results for column, adjacent faces for beam and indirect method for slab. The UPV readings, there are 36 readings for beam, 12 readings for column and 20 readings for slab.
For this test also, the mean The best-fit curve that represents the relationship has the strength obtained from UPV and mean strength obtained from each following equation: member provided the data to achieve a correlation curve.
The 2 regression analysis. The correlation relation between R value is found to be Figure 6 and strength of each member. Essays Figure 6. Malaysia, M.
S thesis However, the development of calibration curves rebound number. The concrete alone is not recommended unless using an regression model achieved from combination of two NDT available specific calibration chart.
Therefore, for engineering investigation, the resulting regression The compressive strength of concrete predicted by the model for strength evaluation could be used securely for Shariati et al. Research by author Figure 8. Essays concrete strength estimation.
