Effect of Recycled PVC Fibers from Electronic Waste and Silica Powder on Shear Strength of Concrete

Abstract
In this study, the electronic waste (e-waste) from PVC cable outer casing was used as fiber in concrete. Fiber-reinforced concrete was made using e-waste fibers of aspect ratio 35 that were incorporated into the concrete at 0.6, 0.8, and 1%, respectively, with respect to the weight of the cement. Silica powder was added to the fiber-reinforced concrete to make silica fiber reinforced concrete by 10% of a volume of the cement. The shear strength of the e-waste fiber reinforced concrete and e-waste with silica powder fiber-reinforced concrete was studied, and the test results were compared with the normal concrete. The addition of silica powder added to the fiber-reinforced concrete improves the shear strength as compared to the shear strength of fiber-reinforced concrete. The shear strength value of fiber-reinforced concrete was reduced to 25.6%, and silica fiber-reinforced concrete was reduced to 21.5% with respect to the normal concrete shear capacity at maximum 1% addition of fiber. Even though the reduction in strength was observed, the e-waste fibers considerably reduced the brittle behavior of the normal concrete. Thus, the use of e-waste fiber in concrete will help to reduce the solid waste management problem and provide for the new fiber material in future research areas of concrete.
