ABSTRACT

Fiber concrete is one of the innovative materials that is still developing and evolving. One of the fiber materials that is currently being studied is PET fiber from plastic bottle waste materials. The effect of fiber on concrete is influenced by the characteristics of the fiber material. One of the characteristics of PET fiber is the weak bonding between the fiber and the concrete which can be overcome by the geometries and dimensions of the fiber. Therefore, this paper focuses on the use of PET fiber from bottle waste with different dimensions: continuous fiber like a layer that was placed in the tensile area of the concrete and short strip fibers that were spread on the concrete, and their effects on the flexural behavior were investigated. Test results showed that the fiber started to be more effective at yield, maximum and ultimate condition, especially for the reinforced concrete beam with continuous fiber. The strip fiber worked earlier in the reinforced concrete beam and then followed by the continuous fiber when the load was continuously applied to the yield point. The continuous fiber improved deflection at the maximum and ultimate load and improved the stiffness better than short strip fiber. In addition, continuous fiber provided better ductility performance than strip fiber where the average ductility of continuous fiber was 20.5 while the strip fiber was 17.1.
