The document experimentally investigates self-compacting concrete with sisal fiber. It includes a literature review on self-compacting concrete and fiber-reinforced self-compacting concrete. The study examines the fresh and hardened properties of concrete mixes containing different percentages of sisal fiber. The results show that adding sisal fiber increases the compressive and splitting tensile strength of the self-compacting concrete mixes. The highest strength gains were observed with the mixes containing the most fiber. The study concludes that sisal fiber has a positive effect on improving the properties of self-compacting concrete and is recommended for use in reinforcing self-compacting concrete.
