Abstract
The research examines the relationship between the use of a concrete tester (CTS02v4) and ultrasonic pulse velocity (UPV) based on the strength characteristics of the Atimbo bridge in the cross-river state of Nigeria. The best fit approach for the cts02v4-UPV relationship under various circumstances is developed by carefully analyzing the correlation between these data sets. As a result, the relation between concrete strength and the CTS-UPV formula is developed by this investigation. From the technical investigation, the residual compressive strength of the concrete abutment was found to be between 29.0 N/mm2 and 40.0 N/mm2. This value is still within the range compared to the expected design value of about 40 N/mm2. The cover to the reinforcement of certain capping beams has an outline of reinforcements, which signifies poor concrete cover, and the mean compressive strength is less than 20 N/mm2. The objectives of this paper are to increase the understanding of processes and the applicability of versatile equipment by making comparisons between the experimental results for both the concrete tester (CTS02v4) and the ultrasonic pulse velocity (UPV), which were used to evaluate the structural integrity of the Atimbo Bridge. Comparisons were made between the UPV method and the concrete tester method using statistical analysis.
