Abstract

Abaca fiber is a strong natural material that can improve concrete. Fly ash, a by-product of coal power plants, can make concrete more workable and durable. Fibers increase strength but may cause voids if poorly mixed. Fly ash reduces this by refining the concrete’s microstructure and improving the bond between fiber and cement. This study tested abaca fiber and fly ash together under normal curing and chloride exposure. Cement was partly replaced with fly ash at 0%, 5%, and 10%. Abaca fiber was added at 0%, 0.1%, 0.5%, and 1%, with a length of 37.5 mm. Concrete samples were cured for 28 days in water and for 45 days in a 10% sodium chloride solution. Compressive and splitting tensile strengths were measured. Results showed that moderate fiber content improved both strength and durability. The best performance came from 0.5% fiber, giving the highest strength. Higher fiber content reduced performance due to porosity and workability problems. Fly ash slightly reduced strength at higher levels but still improved results compared to plain concrete. The most effective mix was 5% fly ash with 0.5% abaca fiber, offering strong mechanical performance and resistance to chloride attack.
