Research

Our research is in the broad area of Multiscale Studies on Cementitious Systems. Specifically, we focus on the following areas:

Multi-blended cements and low-carbon binders,
Durability of concrete,
Thermodynamic and service life modelling,
Reactivity of supplementary cementitious materials (SCMs),
Microstructure and transport in concrete, and,
Developing performance-engineered concrete.

Vision and Mission

We share the vision of IISc in that we seek to contribute to India by offering world-class education to train future leaders in building materials, computational modelling, and sustainability, and applying these skills for India’s wealth creation and social welfare.

Our goal is to develop tools to predict the performance of concrete structures and to develop sustainable building materials aligning with the Sustainable Development Goals of the United Nations, and meet India's climate goals. We are interested in lab-to-field research, i.e., translating our research to field applications of commercial and social relevance to India.

Tools Developed

[1] Performance-Based Concrete Mixture Design

In collaboration with Prof. Jason Weiss and Prof. Burkan Isgor of Oregon State University, we developed a tool to design and optimize concrete mixtures to meet a target mechanical and durability performance. The science behind the tool is outlined in the papers and reports below:

[2] The Pozzolanic Reactivity Test (PRT)

Part of my thesis at Oregon State University was developing the pozzolanic reactivity test to quantify the reactivity of supplementary cementitious materials. This test was developed by Oregon State University and refined over the course of several Ph.D.s, including mine. Using this tool, a user can get the maximum degree of reactivity (DOR*) of an SCM, which is a performance indicator of the SCM as well as an input to models to predict the mechanical and durability properties of concrete made with the SCM. Some papers about the PRT below:
