An Experimental Investigation on Application of Biopolymer in Concrete

Authors- M P Iniya, R Mahalakshmi, S Swathi

Abstract-Biopolymers are being investigated as an environmentally friendly substitute in the manufacturing of concrete due to the growing need for sustainable building materials. This study investigates the use of xanthan gum and cellulose derived from bagasse ash as biopolymer additions in concrete. A byproduct of sugarcane production, bagasse ash is high in cellulose and provides an affordable, eco-friendly substitute for conventional concrete additives. Amicrobial polysaccharide called xanthan gum is known to improve cementitious mixes’ viscosity and workability. These ingredients include cellulose, xanthan gum, fine and coarse aggregate, and cement. The cube specimen measures 150 x 150 x 150 mm, while the cylinder specimen measures 150 mm in diameter and 300 mm in height. Experiments are conducted to examine differences in properties including compressive strength, split tensilestrength and slump cone test. This study highlights the potential of cellulose and xanthan gum as eco-friendly alternatives to conventional chemical additives in concrete, providing a pathway for more sustainable construction practices.
