Sustainable Enhancement of Concrete by Using Waste-Plastic Food -Packages as Economic and Environmentally Friendly Fibers, A Review.

Abstract

Among possible solutions for a cleaner environment is reduction of using non-biodegradable materials to reduce the waste. Solid plastic waste is considered the most important kind of waste in the world, due to its non-decadence and its low organic decomposability. Therefore, it was advised to use this waste as reinforcing materials for concrete units, as it was used as a substitute for moraine in certain proportions and also as reinforcing fibers for concrete. This paper is a review of research investigations that focused on and highlighted the improvement of concrete by recycling waste-plastic food-package and using them as reinforcing fibers for concrete specimens. The impact of plastic waste fibers (PWFs) on workability, compressibility resistance, tensibility resistance, bending resistance, and elastic modulus are demonstrated. It has been noted that the fresh characteristics of concrete decline when mixing plastic fibers with concrete mixtures, while hardened characteristics could be improved by utilizing specific proportion of these fibers
