Abstract


This study investigates the preliminary characterization of locally sourced jute fibre and ground waste glass (GWG) and evaluates their influence on the workability of concrete. Characterization tests included tensile strength, water absorption, density, X-ray fluorescence (XRF), X-ray diffraction (XRD), and thermal properties. The slump cone test was used to assess the workability of concrete mixes incorporating jute fibre (0–1.5% by cement volume) and GWG (0–15% cement replacement). Results showed that treated jute fibres contained high cellulose (67–72%) and moderate hemicellulose (12–16%) with reduced lignin content after treatment, while GWG exhibited a high silica composition suitable for pozzolanic reactivity. Concrete slump decreased with higher fibre content due to increased surface area and absorption, but improved marginally with GWG replacement up to 10% before declining at 15%. The findings suggest that the combination of treated jute fibre and GWG can contribute to sustainable concrete development with acceptable workability and enhanced material performance.
