Dr. Babitha Benjamin

About

Babitha Benjamin holds a PhD in Bioconcrete from the National Institute of Technology, Calicut, and currently serves as Concrete Specialist — R&D at ONX Homes. Research expertise encompasses bacterial (bio-) concrete, 3D concrete printing and additive manufacturing of earth- and cement-based mixes, calcined-clay–based Printcrete (CCP), ultra-high-performance concrete (UHPC), and glass-fiber-reinforced polymer (GFRP) composites. Research activities emphasize sustainable material design, active rheology control for printing, life-cycle assessment of construction methods, and durability-focused mix development.

Notable contributions include a granted patent related to bio-concrete technologies, development of the sprayable mix and leadership in establishing the ONX Homes R&D Centre (Bengaluru) for advanced precast and material innovation. Publication record includes peer-reviewed articles on bacterial concrete and related sustainable construction topics. Professional affiliations include membership of the Indian Concrete Institute and ongoing collaborations across academia and industry to translate laboratory innovations into scalable, circular-construction solutions.
