NOVEL CONCRETES USING SUPPLEMENTARY CEMENTITIOUS MATERIALS AND SEAWATER

Concrete production consumes vast amounts of freshwater, a concern in water-scarce regions. This project explores whether seawater can be used in place of freshwater when paired with supplementary cementitious materials in concrete mixes without steel reinforcement. Researchers will test cement pastes, mortars, and concrete mixtures using both freshwater and seawater to compare hydration behavior, strength, and durability. The work aims to demonstrate proof-of-concept for a more resource-efficient concrete well suited to coastal construction environments.
