Low cost building material is very intending in developing countries. The purpose of this study is to identify the prospect of sisal fiber as a replacement of steel bar reinforcement for structural element. Behavior of lightweight concrete beam was examined to discover the performing sisal reinforcement. Four variation beam specimens of 100 x 150 mm with 1.5 m effective span were tested under flexural loading. The specimens’ variation consisted of one controlling steel reinforcement and three variations of sisal fiber where every variation was represented in three samples. Flexural static loading of simple supported beam were applied and vertical deflections of the bottom mid-span were recorded throughout the test. Test results indicated that the crack moment experiments were higher than the crack moment calculations. The valued were 1.44, 1.52, 2.72, and 3.32 for sisal fiber reinforcement of B-LF, B-MF, B-HF, and for steel reinforcement of B-LS, respectively. Observation results also indicated that the moment resistant capacities of the specimens were twice higher compare to the calculated moment capacity. However, the lowest sisal reinforcement (B-LF) has only about 10% different service moment compare to the steel reinforcement (B-LS) where they both have equal reinforcement ratio = 1.206 %. This indicate that the use of sisal fiber have considered as insignificant different service moment capacity to the steel reinforcement.
