| Abstract: |
Reinforced concrete (RC) structures remain critical infrastructure in water treatment systems globally, yet their long-term durability performance under aggressive chemical environments continues to present significant engineering challenges. This empirical study presents a comprehensive assessment of 47 water treatment facilities across diverse climatic and operational conditions, evaluating structural integrity, material degradation mechanisms, and design performance. Through systematic field investigations, laboratory analysis, and quantitative data assessment, this research identifies critical durability indicators and performance metrics associated with corrosion, alkali-aggregate reactions, and microcracking phenomena. Our findings reveal that 62% of facilities aged 20-30 years exhibited moderate to severe durability concerns, with carbonation depth and rebar corrosion constituting the primary degradation mechanisms. Advanced statistical analysis correlates design parameters, material composition, and environmental factors with observed damage patterns. The research implements optimization strategies utilizing supplementary cementitious materials, enhanced surface treatments, and innovative protective coatings that demonstrated 35-45% improvement in durability indicators. Additionally, this study proposes predictive models for service life estimation incorporating climate data, loading patterns, and maintenance regimes. The integrated methodology provides practical frameworks for design optimization and rehabilitation strategies applicable to existing and future water treatment infrastructure. Recommendations emphasize preventive maintenance protocols, material innovation, and performance-based design approaches to extend facility lifespan by 15-20 years. These findings contribute significantly to sustainable infrastructure development and resource optimization in water management sectors. |
