###### Abstract
By addressing the uncertainties and inaccuracies in the traditional process and employing a fuzzy expert system, this research aims to enhance the decision-making process regarding the maintenance and management of reinforced concrete structures. The utilization of concrete technology literature aids in identifying the types and symptoms of deterioration, facilitating a more comprehensive understanding and diagnosis. [PERSON] and [PERSON] [1] conducted a study focusing on the application of fuzzy concepts to the visual assessment of deteriorating reinforced concrete structures. The authors recognized the subjectivity and ambiguity involved in the visual inspection process and aimed to enhance the accuracy and reliability of assessments. They proposed a fuzzy logic-based approach that incorporated expert judgment and linguistic variables to evaluate the severity of deterioration. The study demonstrated the effectiveness of the fuzzy concept application in providing more robust and consistent assessments of the condition of reinforced concrete structures. It highlighted the potential of fuzzy logic as a valuable tool for supporting decision-making in the maintenance and management of deteriorating structures [1]. In a study conducted by [PERSON] et al. [2], the degradation of concrete exposed to sulfuric acid attack was modeled. The objective of the research was to understand the long-term behavior of concrete in aggressive environments and develop a predictive model based on experimental data. The mathematical model developed by the authors considered various factors, including acid concentration, exposure time, and concrete properties. Through their comprehensive model, valuable insights into the mechanisms of concrete degradation were obtained, providing a reliable tool for assessing the durability of concrete structures subjected to sulfuric acid attack. This research contributes to the broader understanding of concrete performance in corrosive environments and offers practical implications for the design and maintenance of resilient structures [2]. [PERSON] and [PERSON] [3] developed a multi-objective decision-making supporting system for maintenance strategies of deteriorating reinforced concrete buildings. The authors recognized the complexity of decision-making in managing the maintenance of such structures and aimed to provide a comprehensive tool for decision support. The system integrated various criteria, including cost, safety, and environmental impact, to evaluate different maintenance strategies. By utilizing a multi-objective optimization algorithm, the system identified optimal solutions that balanced the competing objectives. The study demonstrated the effectiveness of the decision-support system in aiding decision-makers in selecting appropriate maintenance strategies for deteriorating reinforced concrete buildings [3]. The deterioration of concrete in the marine environment was thoroughly examined by [PERSON] and [PERSON] [4]. The authors explored the specific challenges faced by concrete structures in marine conditions, including exposure to seawater, waves, and aggressive chemicals. Various degradation mechanisms, such as chloride-induced corrosion, sulfate attack, and alkali-silica reaction, were discussed in detail. The study highlighted the significance of utilizing appropriate construction materials, incorporating design considerations, and implementing effective maintenance strategies to mitigate the deterioration of concrete in marine environments. [PERSON] and [PERSON]'s research contributes to the understanding of concrete performance in marine conditions and provides valuable insights into the effective design and management of marine concrete structures [4]. [PERSON] et al. [5] conducted a study on the deterioration progress and performance reduction of 40-year-old reinforced concrete beams in natural corrosion environments. The authors investigated the effects of corrosion on the mechanical properties and structural performance of the beams over time.
