Ultra-high performance concrete (UHPC) is an advanced cementitious material with improved strength and durability characteristics when compared to conventional concrete. Development and characterization of cost-effective and environmentally friendly UHPC are of significance so that it can be used in a wide variety of structural applications. The objectives of the proposed study are two-fold: to develop ecological UHPC with local materials and supplementary cementitious materials and evaluate the long term performance of UHPC in cold climates using "smart aggregate" technology. The scope of the study includes the development of UHPC mixture design with locally available materials and supplementary cementitious materials, evaluation of fresh and hardened properties of UHPC, and longer term performance assessment of UHPC with embedded "smart aggregate" technology in simulated cold climate and repeated cycles of freeze-thaw (F-T).
