Development of Mix Design Nomograph for Polyethylene Terephthalate Fiber Concrete

The aim of this project was to develop of mix design nomograph for PFC that can be used for estimated the required compressive strength and splitting tensile strength with the required PET and water-cement-ratio.The fibers were prepared by using plastic granulator machine SLM 50 FY with size passing 10 mm and retained 5 mm sieve. Different volumes percentages of PET fibers with 0%, 0.5%, 1.0% and 1.5%, were introduced in concrete mixes. The specimens prepared for this study was cylinder concrete with 100 mm diameter and 200 mm height. The laboratory work for physical properties were focused on density and workability, meanwhile for mechanical properties were focused on compressive strength, splitting tensile strength and modulus of elasticity of PET fiber concrete (PFC). The experiment results indicate that the addition of PET fibers significantly decreased the compressive strength and splitting tensile, however the compressive strength still can be acceptable since achieved the mix design The nomograph developed can be used to estimate the desired compressive, splitting tensile strength as well as the modulus of elasticity (MOE).
