Narayanan Neithalath is a Professor in the School of Sustainable Engineering and the Built Environment at Arizona State University. His research interests include:

  • Development and multi-scale characterization of novel binder systems. Studies encompass strategies for sustainable, high volume use of abundant industrial waste/by-product materials in concrete through a ‘materials-by-design’ approach. This involves a fundamental understanding of the rheological properties, reaction kinetics, progress of chemical reactions, and their impact on the resultant pore- and micro-structure that influences the material properties and performance through experiments and modeling (mechanical properties including strength and fracture, durability properties, including moisture and ionic transport). These systems include high volume limestone concretes, alkali activated binders/geopolymers.
  • Carbonation of waste metallic powder from several industrial operations and municipal waste streams to provide a ceramic-like binder material with multi-functional applications (EM shielding, blast/impact resistance, high strength).
  • Use of phase change material embedments to provide energy-related benefits to building envelope systems and crack control to concrete structural elements, and its quantification.
  • Strategies for microstructure characterization and performance. Development of fundamental understanding of pervious concretes and conventional cementitious systems. Computational modeling of the 3-D random porous media through virtual reconstruction and use of modeling tools to predict in-service performance.
  • Microstructure-guided finite element modeling to aid in material design of novel engineering materials with enhanced properties, including systems with non-conventional inclusions, bio-mediated strengthening of porous media, moisture and coupled fracture-ionic transport in concrete and its impact on concrete life cycle, and deleterious reactions in cementitious systems.
