About Me

Greetings! I am Uday Boddepalli, honored to serve as a Prime Minister’s Research Fellow under the esteemed guidance of Dr. Indu Siva Ranjani Gandhi and Dr. Biranchi Panda in the Department of Civil Engineering at the Indian Institute of Technology Guwahati. My current research delves into the fascinating realm of "Studies on Enhancing Rheology, Stability, and Mechanical Properties of 3D Printable Foam Concrete". The focal points of this investigation revolve around the critical aspects of bubble stability and rheology within the foam concrete paste, both of which significantly impact its stability and buildability. In the initial phases of my exploration, I am meticulously examining the characteristics of surfactants to comprehend their influence on the aforementioned challenges. Subsequently, employing a diverse array of admixtures, I aim to elevate the buildability, stability, and mechanical prowess of 3D printable foam concrete. Join me on this academic journey as we unravel the intricacies of innovative approaches to revolutionize the field of construction materials. Stay tuned for updates on the advancements and discoveries emerging from this exciting research endeavor.

Research

Recent technological advancements are paving the way for low-cost, sustainable construction. Among these technologies, 3D concrete printing has the potential to take a significant share of the market for sustainable construction. On the other hand, one of the lightweight concretes that satisfies the demands of modern construction such as thermal insulation, acoustic insulation, and etc. is foam concrete (FC). Even though due to the high amount of cement content in FC is not a good sign from ecological point of view, the additive manufacturing proved to be sustainable by reducing the carbon emissions and resource demands, lowering energy usage, lesser waste generation, and good recyclability. Adopting these new-era construction methods for FC structures accelerates the construction simultaneously improving mechanical and functional characteristics. While designing the 3D printable foam concrete (3DP-FC) dimensional stability plays an important role. In case of classical FC (i.e. mixture of cement, sand, water and foam), due to low yield stress dimensional stability is not achieved. It was also observed that the 3DP-FC shows a more homogeneous distribution of air bubbles with smaller dimensions when compared to the classical FC due to the increased consistency. However, stability of the foam bubble considering the stiff mixtures required for 3D concrete printing and drop in buildability due to reduction of yield stress of the printable material by foam addition are major challenges. These potential gaps identified in the literature are used for formulating the objectives of our research.
