My current research focus is on geopolymer concrete with special emphasis to make it user friendly. The focus is on working towards geopolymer concrete that can be produced in situ with ambient air/normal water curing methods, development of mix design methodology for geopolymer concrete, durability, fracture studies on geopolymer concrete, fibre reinforced geopolymer concrete, studies on structural behavior of reinforced geopolymer concrete, studies on geopolymer concrete as a quick repair material for concrete structures and development of building products such as paver blocks, building blocks through geopolymerization.
NDT of Concrete structures: NDT investigations of distressed concrete structures for formulating rehabilitation methodology and also as a quality check for new structures such as Industrial building, power plant structures etc. Developed a methodology for rapid screening of concrete structures (http://link.springer.com/chapter/10.1007%2F978-94-007-0723-8_175).
Studies on retrofitting of concrete structures through fibre reinforced polymers (FRP): Use of commercially available carbon and glass fibre reinforced polymers to enhance the structural capacity of reinforced concrete structures. Studies were conducted to determine its (FRP) efficiency in enhancing the capacity of reinforced concrete structures with reinforcement corrosion. Studies have also been conducted to determine the long term (5 years) performance of FRP. Studies have also been carried out to studied the behavior of FRP strengthened structures post exposure to elevated temperatures. Studies on Glass FRP rebars as alternate for conventional steel reinforcement
SIFCON (Slurry infiltrated fibre reinforced concrete) Development of SIFCON as an alternate to reinforced concrete structures for blast resistant structures. SIFCON has also been explored as a cover concrete in tension zone to enhance the cracking load, thereby improving the durability of the concrete structures.
