Innovating sustainable construction: GFRP rebar in sea sand and seawater concrete

Sustainability in construction is no longer a choice—it is an imperative.

With increasing resource scarcity and the urgent need to mitigate environmental impact, the adoption of innovative materials and methods has become paramount. Dextra Group, a world leading manufacturer of engineered steel and fibre-reinforced polymer construction solutions, is championing this transformation through its pioneering use of Glass Fiber Reinforced Polymer (GFRP) rebar in conjunction with sea sand and seawater concrete. This groundbreaking approach addresses two critical challenges: the environmental strain caused by the traditional use of freshwater and river sand, and the durability concerns of steel reinforcement in marine environments. By eliminating the corrosion risks associated with chloride exposure, GFRP rebar ensures structural longevity while supporting sustainable practices.

The inclusion of insights from Antonio Nanni, Professor, Department of Civil- and Architectural Engineering University of Miami, further underscores the potential of this innovation to redefine the future of reinforced concrete applications.”
