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.
