This study reports an experimental study on mechanical properties of concrete prepared by polyvinyl alcohol (PVA) fibers. Concrete mixtures are prepared under the same proportions, but by addition of different fibers content. Compressive, splitting tensile and directly tensile tests are carried out for concrete. Primary test results show that, the unit water consumption of mixture was increased with the dosage of PVA fibers, but the slump of concrete mixture was decreased. Experimental results show that, the compressive strength and splitting tensile strength are increased very quickly at the early ages (before the age of 28 days). The compressive strength of concrete is decreased with the increasing of fibers content, but the splitting tensile strength of concrete is increased with the increasing of fibers content. The elastic modulus of concrete was decreased with the dosage of PVA fiber, but the limit tensile strain was increased with the dosage of PVA fiber.
Key words: Experimental test, fiber reinforced concrete, fiber content, mechanical properties, PVA fiber, ,
