MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202621101817 A) filed by Visvesvaraya National Institute Of Technology Nagpur on August 21, 2026, for A Composition Of Sugarcane Bagasse Ash Blended Concrete And Method Of Preparation Thereof.
Inventors include Latkar, Madhuwanti Vinayak; and Khare, Shubhangi Pradeep.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The present invention is related to a composition and method for preparing sugarcane bagasse ash blended concrete, incorporating a biocementing solution based on soya bean hulls' powder as a plant-derived urease source, together with urea and gypsum, for enzyme induced calcium carbonate precipitation (EICCP). Ordinary Portland Cement is partially replaced with untreated, sieved SCBA at replacement level including 20% by weight of cement. The biocementing solution, prepared using two separate mixtures incorporating soya bean hulls' powder and urea with gypsum respectively, is combined with the mixing water without introducing additional water, and incorporated directly into the concrete mix along with fine aggregate, coarse aggregate and water. The precipitated calcium carbonate fills pores and micro- cracks in the SCBA blended concrete, offsetting the strength loss associated with SCBA replacement and reducing water absorption.
