In the last few years with the growth of population, development of industry and technology there has been rapid increment in the waste materials and by-products production. The basic strategy to decrease solid waste and plastic waste bottle disposal problems have been focused at the reduction of waste production and retrieval of usable materials from waste as raw materials . In present study, the PET fibers were achieved by manually hand cutting from Kinley polyethylene terephthalate (PET) plastic drinking water bottles. Three different geometrical shape Straight shape fiber, Flattened shape fiber and ‘O’ shape polyethylene terephthalate (PET) fibers 0.5% by weight of cement were used. Fine aggregate were partially replaced with copper slag at percentages of 0%, 20%, 40% and 60%. Effect of different geometry of PET fiber and copper slag on fresh and hardened properties of concrete was investigated. Test result revealed that geometry of fiber and copper slag has good effect on fresh properties of concrete. Without use of super plasticizer workability was increasing. The combination of O shape fiber with 60% copper slag demonstrate enhancement in compressive strength, split tensile strength and flexural strength up to 25.85%,26.39% and 28.09% respectively compared to standard mix M 25 grade concrete. With the Increment of copper slag enhancement in strength was observed it was due to the friction developed between copper slag and PET fiber surface. Development of friction was due to the angularity of copper slag particles and bridging action of PET fiber. From water absorption test result it was concluded that water absorption is less in O shape fiber. It is due to the less water absorption properties of PET fiber and copper slag and also the O shape fiber provide good interlocking property in concrete matrices compare to other two geometrical shape fiber.
