摘要

This research focuses on the need for strengthening urban infrastructures in the Indian subcontinent by incorporating eco-friendly additives into concrete by the addition of fibres such as cellulose and nanocellulose derived from easily available biomass. Commercial microcrystalline cellulose and sugarcane bagasse cellulose were both added 0.5% into the concrete replacing the cement to check the enhancement in the mechanical properties of concrete. Cellulose was further converted to nanocellulose using ultrasonication and homogenization. These are added to the concrete to make M30 cubes (weight of water to cement = 0.4; Cement:Fine aggregate:Coarse aggregate = 1:1.77:3.25). The utilization of nanomaterials in cement concrete, resulted in improvement in the strength after adding nanocellulose by up to an average of 55% for compressive strength, 25.5% for Split tensile strength and 23.5% for Flexural strength. FTIR spectra and XRD showed the peaks of different functional groups and crystallinity of cellulose respectively. A particle size analyser of nano-cellulose showed and verified the range of 40–100 nm. SEM images were used to confirm the micro-level bonding of cement with cellulose and nanocellulose. Overall mechanical properties of concrete improved tremendously using ecofriendly cellulose and nanocellulose.
