Extraction and characterization of nanocellulose from bemban fibre for cement-based composite

Year: 2024

Type: article

Abstract: The utilization of natural fibers in composite cement faces issues due to the presence of lignin and hemicellulose , which hinder the strength of the fibers as reinforcements. This study aims to investigate the characteristics of Bemban Fibres ( Donax canniformis )/BF as reinforcement in cement-based composite. Cellulose was extracted from the stem fibres using alkali treatment , bleaching, and acid hydrolysis methods to obtain Bemban Fibre Nanocellulose (BFNC) which exhibits favorable compressive strength properties. Microstructural characterization was conducted through X-ray Diffraction Analysis (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), and Thermogravimetric Analysis (TGA). Compressive strength testing was performed on cement-based composites with the addition of BFNC at 0 %, 1 %, 2 %, and 3 % by weight. The results indicated that BFNC contains 42.4 % cellulose. The diameter of the BFNC ranged from 6 to 28 nm. BFNC exhibited significant potential in terms of thermal properties compared to untreated fibers. As a highly effective reinforcing component, it demonstrates excellent resistance to degradation at elevated temperatures and improves the mechanical strength of the cement-based composite. The incorporation of 1 % BFNC was found to improve the compressive strength by 9.38 % compared to the control specimens. This indicates that BFNC processed through acid hydrolysis has a better surface and enhanced bonding capabilities between particles. The utilization of 1 % BFNC has been proven effective in increasing the compressive strength of cement composites , making it suitable as a reinforcing material and feasible for application in construction.
