Abstract
The study results show the use of jute fibers to develop a low cost material for wall panels, roofs and other construction board. The study has been investigates the cement mechanical characteristics jute fibers reinforced concrete. Different lengths of fibers (2cm) and (4cm) were mixed to act as reinforcement for the concrete samples. The samples with different fiber percentages (0.5%, 1% and 1.5% by weight of cement) were tested in axial compression and splitting tensile strength. A total of (42) concrete cube samples (100mm*100mm*100mm) and (42) cylindrical samples (100mm*200mm) were used in the tests, these include compressive and splitting tensile strength and were conducted at (7) and (28) days of concrete age. The results showed that increasing the fiber content and length leads to a slight decrease (4.3% - 12.3%) in the compressive strength but it improves the splitting tensile strength which reached best value at the (1% by weight of cement) fiber content and (5cm) length. The increasing of splitting tensile strength was up to (19.4%) from the reference concrete strength.
