Grant: Idea to Innovation

Ultra-High performance concrete (UHPC) is a fiber-reinforced, densely packed concrete material which exhibits compressive strength exceeding 150 MPa and superior durability than normal and high-strength concrete. The high amount of cement, silica fume, quartz powder and quartz sand in conventional UHPC cause not only high cost of powders in the UHPC, but also some drawbacks when sustainable development is considered. In order to achieve the sustainability development at low cost and achieve ecological concrete, a new type of Ultra-high Performance Glass Concrete (UHPGC) was developed through the use of waste glass materials with different particle distributions. A U.S. provisional patent application files this technology in March 2013.UHPGC with improved properties can be designed using different waste glass products: glass sand, high amount of glass powder and moderate content of fine glass powder, silica fume and water-reducing admixture. This technique gives multi advantages through valorization of waste glass, production of low cost and high quality UHPC for different construction sectors, and achieving sustainable construction issues. This scope project is to scale-up of this technology to the pilot scale and develop applications in the fields of the repair material and structural concrete elements. This project will enable to bring adjustments to the technology for large scale production.
