| الوصف: | This paper examines the effect of using PET bottle waste as a reinforcement bar in concrete beams. Waste of PET bottles has been cut by a special tool to long strips with width of 6 mm and thickness of 0.5 mm and lengths ranging between 6000 mm for small bottles and 11000 for large bottles. Then, straps areused in the formation of PET bars in three different forms, two braids are formed and twisted bundles form.Each PET bar consists of 36 straps. PET bars are arranged in the same location of rebar as an alternative to the steel bars in the tensile area. Also, it are pre-tightened before casting with a special tool is designedfor this purpose in order to give it a straight texture and reduce the expected elongation. Five concrete beams with dimensions (150*200*1400)mm are used in this study.Two of themare controlledbeams with and witout tension steel reinforcement.The other three beams are reinforced withthree different forms of PET bottle waste bars. The achieved results are encouraged and unprecedented as the models containing rods achieved a maximum failure load of up to 25% of the failure load for specimens containing reinforcing steel bars.This technique enhancesits ability to be used as reinforcing bars in secondary structural members. |
