STUDY OF POLYETHYLENE TEREPHTHALATE PET PLASTIC BOTTLES FIBER IN FLY ASH CONCRETE WITH PARTIAL REPLACEMENT OF FINE AGGREGATES BY IRON SLAG

In present day plastic waste is increase day by day. Waste plastic bottles are major causes of solid waste disposal problems. This induced an environmental issue as waste plastic bottle are difficult to biodegrade and involves process either to recycle or reuse. Hence an attempt has been made to understand whether it can be successfully used in concrete to improve some of the mechanical properties and strength of concrete. Iron slag is one of the industrial by-products from the iron and steel making industries. Iron slag is an industrialwaste by-product of steel industry These Iron slag are materials which does not have a higher scrap value and are considered waste. This industrial waste demolition is dumped and they cannot be recycled. They even pollute the atmosphere and are hard to dispose. In this study the study of polyethylene terephthalate PET plastic bottles fiber in fly ash concrete with partially replacement of fine aggregate (sand) by Iron Slag. Iron slag as partially replacement of fine aggregate in different percentage 10%, 20%, and 30% in fly ash concrete. The PET plastic bottles are cut in the form of fiber. The length of fiber was kept 2.5cm and breadth was 0.5cm.Then molds in the form cubes, cylinders and beams were casted in the laboratory, cured and tested (i.e. compressive strength, flexural strength split and tensile strength) has observed. To investigate the fresh concrete properties, the slump test was conducted for every batch of various percentage of waste iron slag. While for hardened concrete properties, compressive strength test, splitting tensile strength test and flexural strength test were conducted. The results indicate that the concrete with added of waste PET bottle fiber reduce the workability and compressive strength of concrete and the mechanical properties and durability properties of concrete by adding Iron Slag by partially replacement of sand in various percentage. However, for splitting tensile strength test and flexural strength test, it showed a strength development of concrete when added of waste PET bottle fiber and Iron slag
