E-waste Abstract - This paper present an experimental study on plastic type fiber of different length, a small size of e-waste concrete short columns reinforced with hybrid fiber plastic will show good result in properties of concrete as under axial loading condition. The strength and compared with the larger size. In this paper, the extracted durability of concrete short column improve with the addition of fiber. Fibers added to the concrete at 0.6, 0.8 outer casting of electronic wire was used for making e-waste and 1% of e-waste and 0.5,1 and 1.5% of micro steel fiber. Fiber reinforced concrete helps to reduce the crack fiber with respect to the weight of concrete on the propagation and increase the mechanical properties strength criteria of M30. In hybrid fiber concrete, the compared to the normal concrete. In hybrid concrete, the micro steel fiber delayed the development of macro micro fibers delayed the development of macro cracks and cracks and e-waste fiber helps to improve the greater strength and crack resistance. It also improve the mechanical properties of concrete .When using e-waste mechanical properties of concrete. The strength and the fiber in concrete it reduces the amount of dumping ecorresponding deflection was increase linearly with plastic waste into nature. A total of eight column increasing steel fiber content in concrete. Effect of two or specimen consisting of one normal RCC column, four more fibres used in concrete gives the benefits of individual fiber reinforced column and three hybrid fiber reinforced fibres and also improve desired properties of concrete. column were tested. The experimental result reveals that Hybrid fiber has been shown to be applicable to many types the optimal percentage addition of fibers to the concrete of RC structural elements. Several studies carried out on was found to be 0.8% of e-waste and 1.5% of micro steel testing reinforced concrete short columns with different fiber with respect to the weight of concrete. Result show types of fibers. From this studies, we can conclude that to that a combination of micro steel and e-waste fibers can investigate the behavior of hybrid fiber concrete short be efficiently used to optimize the behavior of concrete. columns under axial loading condition. Hybrid fiber reinforced short columns were capable of carrying large amounts of strain than normal RC 2. LITERATURE REVIEW column.

1. INTRODUCTION In the recent years, the various fibers were developed and used in the construction industries. Steel is mainly used fiber in concrete for various applications. Also glass fiber polythene fibres, carbon fibres, polyamide fibres ,sisal fiber are now developed and also used in construction, industrial and infrastructure development. Some electronic waste fibres can also be used in concrete. Electronic waste is considered more toxic than municipal waste. When e-waste used in concrete, it reduces the environmental pollution and solid waste problem. E-waste in concrete is the new Š 2017, IRJET

Several reports on the design and construction reinforced concrete have been published which provide information on the use of e-waste and micro steel fiber materials. Arjun Ramakrishna Kurup and K. Senthil Kumar carried out experimentally investigated on fresh and hardened properties of varying percentage fiber reinforced concrete and normal concrete .To enhance the properties of concrete, silica powder added to the FRC with 10% replacement of cement. Hardened properties of both FRC and SFRC is linearly increased by increasing the fiber content compared to normal concrete. Ashwini Manjunath B(2016) conducted an experimental study on utilization of e-waste particle as coarse aggregate in concrete with a percentage replacement. Fibers added to the concrete ranging from 0%,10%,20% and 30%. Compared with conventional concrete, the strength is reduce:-coarse aggregate replaced by 20% of e-plastic waste. It is because of decreasing the adhesive strength between the materials. K.Senthil Kumar and K.Baskar(2015) ISO 9001:2008 Certified Journal
