Sustainable Construction Strategies for Enhancing the Durability of Concrete Structures in Coastal South-South Nigeria: A Comparative Review of Global Best Practices and Material Innovations

Concrete structures in coastal regions of South-South Nigeria are increasingly threatened by weather-induced deterioration caused by high humidity, salt-laden winds, frequent rainfall, and aggressive marine conditions. This paper investigates sustainable construction strategies and material innovations to enhance the durability of concrete buildings in these environments. Drawing on a comprehensive review of global best practices from the Netherlands, Japan, the USA, and Australia, the study examines the applicability of high-performance concrete (HPC), geopolymer concrete (GPC), self-healing concrete, and corrosion-resistant reinforcement in mitigating structural degradation. The methodology involved comparative literature synthesis and contextual evaluation of international case studies relative to Nigeria’s coastal climate. Findings reveal that integrating advanced concrete technologies with climate-responsive designs such as elevated foundations, passive ventilation, and waterproofing systems significantly improves structural longevity and reduces maintenance costs. The study recommends revising national building codes to incorporate these sustainable practices, investing in pilot projects using innovative materials, and promoting industry academic collaboration. This research contributes to advancing sustainable construction in tropical coastal environments by bridging global innovations with local challenges in Nigeria’s built environment.
