Innovative Bio-based Binder for Concrete Infrastructure

Concrete is the most widely used infrastructure material and its production is expected to increase at a rate of five percent annually. Innovative research is continually needed to improve the overall performance of concrete infrastructure.

With sustainability and resiliency issues becoming major driving forces in concrete development, Ali Ghahremaninezhad, an assistant professor in the University of Miami (UM) College of Engineering’s Department of Civil, Architectural and Environmental Engineering, received funding from Oceans Technology Group to investigate an innovative bio-based binder for concrete materials.

Nature has created biological materials with superior mechanical and functional properties compared to the traditional engineering materials. Inspired by nature, Ghahremaninezhad will study the underlying mechanisms responsible for the enhanced properties of the bio-based binder.

Ghahremaninezhad and his team will investigate the mechanical properties, durability, chemical characteristics, and microstructure of the bio-based binder utilizing advanced state-of-the-art characterization techniques.

“This bio-based binder has the potential to produce cementitious materials with improved sustainability compared to traditional concrete,” says Ghahremaninezhad. “The potential benefits of this binder include high resistance to water and acid attack, enhanced strength and flexibility, and biocompatibility.”

“Research on bio-inspired methods to enhance infrastructure materials is at the core of our mission,” he says. “This research is necessary for the development of design guidelines and standards for the implementation of the innovative binder in various applications.”
