Strength Characteristics of PVC Coated Welded Wire Mesh as Steel Fiber Reinforced Concrete

Indradi Wijatmiko, Ari Wibowo, Christin Remayanti Nainggolan


Fiber concrete containing fibrous materials is manufactured to improve the low tensile strength of concrete and its brittle properties. In this research, fiber obtained from PVC coated welded wire mesh with diameter of 1 mm was utilized. There were several variations of fiber concrete samples made. Samples were subjected to tensile and compressive strength tests. The elastic modulus was measured by using extensometer and strain-stress gauges. The results show that the incorporation of PVC coated welded wire mesh increases the tensile strength of concrete, when the percentage of the fiber is 1.5%, with the length of 3.6cm, and the interlocking of 1.2cm. However, the compressive strength is slightly reduced from the normal ones. The elastic modulus results show that the introduction of PVC coated welded wire mesh tends to reduce the flexibility, as the value reduced 15-50% as compared to the normal ones without any fiber
