| Summary: | Concrete is known to have high compressive strength, stiffness, low thermal and electrical conductivity and low toxic. Another important thing that concrete can be shaped into geometrical properties. However, concrete is brittle and weak in tension. When subjected to tensile stress, unreinforced concrete will crack and fail. Reinforcement with randomly distributed short fibers presents an effective approach to curb the crack propagation and improving the ductility and tensile strength of concrete. Even though there a lot of researches have been done on the use of oil palm waste or fiber in concrete and mortar but none of the researchers have use fiber from oil palm trunk as concrete reinforcement. Therefore in this study, an investigation was made on the use of fiber from oil palm trunk in concrete. Five different concrete mixes with different length of fiber content namely 0mm, 25mm, 35mm, 45mm and 55mm were cast at a constant fiber volume of 1%. The parameters tested are flexural strength and compressive strength. It was found that there is an increase in compressive strength when compared with normal concrete but among the different length there is not much different. In terms of flexural strength there is an increased in strength as the length of fiber increases. |
