Engineering Properties of Foamed Concrete Reinforced with Sustainable Bamboo Fibre

Abstract

The consumption of foamed concrete (FC) in conjunction with the incorporation of natural fibre is recognized as an outstanding effort in promoting sustainable practices. This effort is aimed at reducing greenhouse gas emissions and the impact it leaves behind on the environment. The goal of this experiment is to discover the viability of incorporating raw bamboo fibre (BF) into the fabrication of 1000 kg/m3density FC. The shrinkage, flexural, compressive, and tensile strengths of the material were the four characteristics that were considered throughout the analysis. The weight fractions of BF that were utilized were 0.0%, 0.1%, 0.2%, 0.3%, and 0.4% respectively. According to the results, the FC-BF composites’ drying shrinkage, compressive, flexural, and tensile strengths were best achieved when 0.3% BF was present. This was caused by the BF’s adhesion to the cementitious matrix of the FC. Additionally, BF functioned as an anti-micro crack that prevented FC from developing internally induced microcracks and cracks.
