Sustainable Innovation: Brine-Based Concrete Using Desalination Waste

Abstract

Brine disposal from desalination plants is a significant environmental challenge, often leading to marine ecosystem disruptions, groundwater salinity rise, and waste of valuable resources. This research explores the innovative application of desalination brine in sustainable concrete production. The study examines the physical, chemical, and mechanical properties of concrete prepared with brine-based mixing water and partially substituted aggregates. Laboratory analyses include compressive strength, durability, micro structural characterization, and leaching potential of salts. The findings suggest that, with proper treatment and mix design optimization, brine-based concrete exhibits mechanical performance comparable to conventional mixes, while simultaneously reducing environmental impact. This paper contributes to sustainable material innovation, resource recovery, and desalination waste management by establishing a pathway for large-scale adoption of brine-based concrete in infrastructure development.
