Dr. Chidiac’s research overarching focus is Sustainability and Resiliency of materials and structures. Within this focus, four research themes are studied. 1) Design, rheology and durability of self consolidating concrete (SCC) and ultra high-performance concrete (UHPC); 2) Self healing of concrete cracks at multiple scales; 3) Self diagnosing and healing of concrete; and 4) Energy efficiency of buildings. The research is multiscale and multi-science and includes both experimentation and modelling.
