This paper presents the effect of 3 different fiber types on the flexural performance of compacted cement-fiber-sand (CCFS)with 4 fiber fractions (0.5, 1.0, 1.5, and 2.0% by volume). The types of fibers are short steel, long steel, and polypropylene fibers. The overall CCFS performance was divided into 5 sub-design performance indicators: (1) peak strength, (2) peak-to-first peak strength ratio, (3) residual strength ratio, (4) toughness, and (5) equivalent flexural strength ratio. Finally, the effectiveness of each fiber type was compared and rated in terms of the overall performance. The results show that the long steel fiber provided the best overall sub-performance, resulting in excellent overall flexural performance.
