dc.description.abstractGrowing environmental concerns have intensified research into sustainable construction materials, such as natural fiber-reinforced concrete. Among these, lightweight foamed concrete (LFC) stands out for its reduced material consumption, improved thermal insulation, and lower environmental footprint. The integration of natural fibers, such as sugarcane bagasse fiber (SBF), into LFC has the potential to further enhance its performance. This study investigates the influence of varying SBF weight fractions (0%, 1%, 2%, 3%, 4%, and 5%) on the physical, mechanical, and durability properties of LFC with a target density of 1000 kg/m3. The primary objective was to determine the optimal SBF content for achieving superior material characteristics. Experimental results revealed that the inclusion of 4% SBF provided the best overall performance, improving compressive strength by 53%, increasing ultrasonic pulse velocity (UPV) by 17%, and reducing drying shrinkage by 58% compared to the control mix. Additionally, slump flow decreased progressively with higher fiber content, indicating enhanced cohesion. Water absorption and porosity were significantly reduced with increasing SBF, with the 5% mix showing up to a 19% decrease in water absorption. Thermal conductivity also declined slightly, suggesting improved insulation properties. Microstructural analysis confirmed better fiber-matrix bonding at the optimal fiber content, contributing to the observed improvements in performance. This study offers valuable insights into the mechanical, thermal, and durability characteristics of LFC-SBF composites, highlighting their potential as sustainable construction materials.
