Abstract
This study presents the fresh and mechanical properties of concrete made with recycled aggregates (RAs) and coconut fibers (CFs), with an emphasis on the development of sustainable and ductile cementitious composite through the valorization of coconut and construction wastes. For this purpose, the effect of different percentages of CF, i.e., 0%, 1%, 2%, and 3% by wt. of cement, was examined on the mechanical and physical properties of concrete incorporating RA (0%, 30%, 50%, and 100%). To avoid the negative effect of CF on workability, a plasticizer was used to achieve the target workability. The performance of mixes was evaluated based on the results of workability, density, compressive strength (CS), splitting-tensile strength (STS), flexural strength (FS), and water absorption. The results showed that incorporation of 1–2% CF improved the CS and STS of concrete for each constant level of RA. The addition of 2% CF is recommended for maximum mechanical performance. Concrete incorporating 50% coarse RA with 2% CF showed CS comparable to conventional concrete. Concrete made with 100% coarse RA and 2% CF showed STS and FS comparable to that of conventional concrete. This study recommends the use of 2% CF along with plasticizer to attain the best mechanical performance. Despite comparable STS and FS, 100% RA concrete with 2% CF produced 25% lower CO2 emissions than conventional concrete.
