This paper describes the investigation of mechanical and durability properties of lightweight foamed concrete (LFC) with the inclusion of fibers. All the specimens were tested using the density of 1000 kg/m3. The cement, sand and water ratio used was 1:1.5:0.45. Polypropylene and kenaf fiber were used as additives by volume fraction and 30% of fly ash was replaced by cement. The experiment was setup to examine its mechanical and durability properties with accordance to standard method of testing. With reference to the result analyzed, fibers inclusion has least contribution in compressive strength or might also lessen the result but the integration of fly ash in the mic has the ability to enhance the compressive strength. The higher percentage of fiber inclusion is proven to have contributed more on flexural, tensile splitting and shrinkage properties of LFC.
