MUMBAI, India, July 11 -- Intellectual Property India has published a patent application (202541060870 A) filed by Akshaya College Of Engineering And Technology, Coimbatore, Tamil Nadu, on June 25, for 'experimental investigation on bubble deck concrete slab.'
Inventor(s) include Mr. M. Sheik Mohamed Anas; Mr. Jestin John; Mr. C. K. Srikathir; and Mr. T. Veerappan.
The application for the patent was published on July 11, under issue no. 28/2025.
According to the abstract released by the Intellectual Property India: "The proposed invention is a Bubble Deck concrete slab system that integrates hollow spherical voids between reinforcement layers to reduce self-weight and material usage without compromising structural performance. These voids, formed using plastic balls, replace non-functional concrete from the slab's neutral axis, reducing concrete volume by up to 35%. Positioned within a mesh grid and secured to prevent displacement, the voids allow for greater span lengths, decreased dead loads, and optimized foundation design. The system can be cast in-situ or manufactured as precast units and is compatible with self-compacting concrete. It supports sustainable practices by enabling the use of recycled materials and reducing overall construction waste. Experimental studies confirm that Bubble Deck slabs exhibit load-carrying capacity and failure behavior similar to traditional solid slabs. The invention offers enhanced design flexibility, reduced environmental impact, and faster construction timelines. It is ideal for multi-story buildings, bridges, and infrastructure where efficiency, sustainability, and structural performance are paramount."
