Narayanan Neithalath’s research focuses on the development and characterization of novel and sustainable cementitious materials and systems for infrastructure.

His research includes pervious concretes through the development of efficient material design processes, understanding pore structure-property relationships and material modeling. He is currently pursuing research on novel and non-standard cement replacement materials for concrete such as glass powder and limestone powder. Replacing a portion of cement in concrete contributes to sustainability in construction because cement is the most resource- and energy-intensive material used in concrete.

Neithalath also works on energy efficiency attained through material modifications in concrete where phase change materials and other composite systems are used to make the building envelope more energy efficient.
