Condition Assessment of Existing RCC Building Using Non-Destructive Testing

Abstract

The growing importance of maintaining and extending the functional lifespan of reinforced concrete structures has resulted in an increased emphasis on non-destructive testing techniques as essential tools for evaluating structural conditions. Non-destructive testing procedures offer a notable benefit in assessing the uniformity, homogeneity, ability to withstand compression, durability, and degree of corrosion in reinforcing bars within reinforced concrete structures. This study aimed to evaluate the existing condition of partially constructed residential buildings in Rewari district, located in the state of Haryana. The reinforced concrete structure of the building had been completed eight years ago, however, the project was abruptly stopped. Prior to recommencing the construction, it is important to assess the present state of the structure in order to evaluate the deterioration in Reinforced Cement Concrete (RCC). The building's state was evaluated by visually inspecting the building, conducting on-site examinations, and analyzing samples in a laboratory. The findings emphasize the assessment of the robustness and durability of concrete to ascertain the degree of deterioration and degradation in the structure. The study incorporates visual inspection, and non-destructive evaluation utilizing different instruments to evaluate the corrosion condition of reinforcing bars. In addition, selected RCC columns, beams, and slabs undergo chemical testing. It has been observed that the strength results and chemical results were within permissible limits.
