Engineered Geopolymer Composites (EGC) for Sustainable Transportation Infrastructure

The objective of this study is to develop novel Engineered Geopolymer Composites (EGCs) implementing locally available ingredients to produce a new generation of materials that are practical, cost-effective, and eco-friendly for repair and new construction of transportation infrastructure in the South-Central region. In order to achieve this objective, EGC mixtures will be designed with different types and proportions of locally available precursor materials (mainly locally available fly ash and metakaolin). EGCs fresh and hardened properties will be evaluated to identify key parameters ensuring EGC strain hardening response as well as optimum design of the composition balancing fresh and hardened properties. Furthermore, bonding properties of EGC with regular concrete will be assessed. Finally, a cost analysis for EGC implementation will be performed by comparing the cost of EGC materials to current materials utilized in the field.
