Stress-Strain performance characteristics for Polyethylene Terephthalate Fibre Concrete

  • P.S.Kumar, B.Jeyanth


The main aim of this research is to reuse the waste polyethylene Terephthalate (PET) cool drink and normal bottle as a useful entity in concrete. This is often done by converting the pet bottles into thin fibers and intermingle these bottles within the concrete within the sort of pet fibers. The compressive, split tensile, Flexural strength and compressive stress strain curve characteristics of M40 grade waste pet fiber reinforced concrete was investigated. The fibres were added on the idea of ratio. The aspect ratios of pet fiber which are utilized in this project are 4, 8 and 12. The results of compression test, split lastingness test, flexural strength test and compressive stress strain curve test are compared between the three aspect ratios. The ratio with highest value within the entire test is going to be emphasized as the best. By comparing the results of the test with different ratio, the optimum size of the fibre are often obtained.
