Utilization of silica fume coated waste PET flakes in concrete

Abstract

The purpose of this study is to use SF-coated flakes obtained from PET bottles in cementitious materials instead of SF-uncovered PET discarded flakes. The fundamental objective of this experiment is to see how encapsulating waste plastic materials with mineral additives such as silica fume impacts the fresh and stiffen characteristics of concrete. A previous investigation into the usage of several kinds of plastic shapes in the cement pastewas also conducted. The inadequacy of connecting between both the concrete mix and the plastic is the main source of concern, as the strength falls short of the grade's requirements. The goal of this research is to increase the interfacial adhesion of discarded PET flakes with cementitious material by covering them with a chemical additive like silica fume and using epoxy resins as an adhesive. Either of these benefits includes that by using plastic materials leads to lightweight concrete, determined by the amount of discarded plastic contained. The experiment was carried out by combining PET plastic flakes with dimensions of (10 × 15) mm. as bond weight at four different intervals of 0 %, 1.5 %, 3 %, and 4.5 %. The contemporary and solidify properties of cement matrix were examined over the inclusion of SF-coated plastic flakes and conventional PET flakes.
