Abstract
prevents structural damage, is a crucial aspect of this study. The ultrasonic pulse velocity and Schmidt rebound hammer were used for this investigation; these methods have been employed for a considerable period to analyze damage, cracks, voids, and other deterioration in concrete structures. Nevertheless, in an extreme environment with high humidity levels in the atmosphere, significant pollution, the presence of CO2 and chloride contents in the atmosphere, NDT using ultrasonic pulse velocity or rebound hammer can be effectively utilized to predict the service life of the structure, in addition to quality control for both new and old structures, as well as structural health monitoring.
Structural health monitoring (SHM) is important when it comes evaluating various structures and infrastructure. This involves the inspection, monitoring, and maintenance to sustain economics, enhance quality of, and promote sustainability in civil engineering. Some buildings have also failed due to faulty design or construction. The various causes of structural failure along with the principles of rehabilitation of structures will be discussed in the following content. The concept of nondestructive testing (NDT) is to receive material properties of in place specimens without destroying specimen nor the structure from which it is taken. However, the one issue that has been prevalent in the concrete industry for years is that the true properties of an in-place specimen have never been tested without leaving a certain degree of damage on the structure.
1.1 The generic features of NDT methods are discussed: 1. Rebound Hammer 2. Ultrasonic Pulse Velocity Test
The use of the ultrasonic pulse velocity tester is introduced as a tool to monitor basic initial cracking of concrete structures and hence to introduce a threshold limit for a possible failure of the structures. Experiments using ultrasonic pulse velocity tester have been carried out, under laboratory conditions, on various concrete specimens loaded in compression until failure.

1.1.2 REBOUND HAMMER The rebound hammer test is a quite common method used in the construction field to assess the strength compressing of concrete structures. It operates by striking the surface of the concrete with a spring-loaded hammer, subsequently measuring the rebound distance. This particular test provides very valuable information about concrete integrity and durability, helping engineers alongside builders ensure the good quality of their constructions

1. INTRODUCTION Ever so since the start of the 20th century, concrete has become the primary building material used in most constructions. After examining numerous structures constructed with concrete, it has been observed that concrete can be vulnerable to deterioration in varying circumstances, making the assessment and rehabilitation of concrete buildings an important issue. Assessment can be extremely beneficial for identifying potential damage to structures and determining the causes of its likelihood. This investigation, based on non-destructive testing (NDT), aims to access information and structural health monitoring for concrete structures, particularly in the context of historic structures. The benefit of this NDT investigation, which
