“…Furthermore, the compressive force of concrete can be assessed by rebound hammer testing [7]. Rebound hammer testing dramatically reduces strength for high-volume hover ash concrete, although ultrasonic pulse speed testing reveals comparable compressive strength between fly ash concrete and ordinary concrete on altogether eternities [8]. Nondestructive testing for assessing the safety of structures is made possible by the multi-variation equation, which can efficiently connect the concrete compressive force and ultrasonic pulse speed values [9].…”

This paper mainly dealt with the evaluation of the structural stability of four storied building using non-destructive on-destructive testing methods. During the construction stage, there are many tests available to assess the excellence of concrete. The quality of concrete mainly depends on the quality of materials, concrete grade, and water-cement ratio. In the case of existing structures, to check the quality of concrete destructive tests are not possible, meanwhile, concrete quality will be assessed by using non-destructive testing (NDT) techniques such as rebound hammer, ultrasonic pulse velocity (UPV) etc. In this present study, an attempt has been made to check the quality of concrete in an existing four-storied building using non-destructive testing methods such as rebound hammer test and ultrasonic pulse velocity test. Moreover, the stability of the structure was also assessed. Non-destructive testing method was chosen since existing information of the structure was unavailable. Test results showed that the basement (B1) was susceptible to corrosion, and the compressive strength was not in the recommended range. Ultrasonic pulse velocity (UPV) results also proved that the average quality of the concrete was poor. Hence, significant suggestions were given for necessary retrofitting measures to improve the stability of the structure.
