Bengaluru: The Department of Civil Engineering at JAIN (Deemed-to-be University) organised a specialised Guest Lecture on “Geopolymer Concrete” on 12 November 2025 at the School of Engineering and Technology campus, Bengaluru. The session was delivered by Mr Akash Babu L., a Research Scholar at the University Visvesvaraya College of Engineering (UVCE), and was attended by students and faculty members, who actively participated.

The lecture formed part of the department’s ongoing efforts to introduce learners to emerging sustainable technologies in civil engineering. Organised by Prof Pavan P. S. and coordinated by Dr Raghavendra Prasad H. D., the event explored the scientific, environmental, and industrial significance of geopolymer concrete as a low-carbon alternative to Ordinary Portland Cement (OPC). A total of 51 participants attended the event, reflecting strong academic interest in the domain of sustainable construction.

During the session, Mr Akash offered an in-depth overview of geopolymer technology, explaining the role of industrial by-products such as fly ash, GGBS, and metakaolin in forming geopolymer binders. He discussed the chemistry of alkaline activation using sodium hydroxide and sodium silicate and elaborated on key performance parameters such as molarity, Si/Al ratio, curing conditions, and mix optimisation.

The lecture captured current research advancements, including one-part geopolymer systems and ambient-cured mixes suitable for practical applications. Emphasising sustainability, the speaker highlighted that geopolymer concrete can reduce CO? emissions by up to 70 per cent when compared with conventional OPC-based systems. Experimental results demonstrating high compressive strength, durability in aggressive environments, and improved microstructural properties (as supported by SEM analyses) were presented to the audience.

The session concluded with an interactive discussion, where students and faculty explored potential areas for future research, mini-projects, and industry-aligned experimentation. Dr Dasarathy A. K., Head of the Department, delivered the vote of thanks and presented a token of appreciation to the speaker.

Reflecting on the importance of the session, Dr Dasarathy remarked: “Introducing students to sustainable construction technologies is essential for shaping the future of civil engineering. This lecture not only deepened their technical understanding but also encouraged them to participate in research that directly contributes to environmental responsibility.”

The event reinforced the university’s commitment to promoting sustainable engineering innovations and fostering research-oriented learning. Future sessions and workshops in advanced materials and green construction technologies are planned as part of the department’s academic initiatives.
