Evaluation of Fresh and Hardened Properties of Concrete Comprising E-Waste

Owing to rapid urbanization and population expansion, an increase in plastic utensils leads to an increase in plastic waste. Research in the domain of the recycling and repurposing of plastic waste in the construction industry offered a solution to decrease plastic waste as relief for environmental damage and protecting natural resources. This study is about replacing natural coarse aggregate in concrete with plastic coarse aggregate (PCA), which is made from electronic waste. Natural coarse aggregates (NCA) are replaced by PCA as 10%, 15%, and 20%. Rheological and mechanical properties i.e., workability, concrete density, compressive strength, and split tensile strength are investigated. The durability of concrete is assessed by water absorption, abrasion resistance, Sorptivity, Sulphuric attack resistance, and thermal conductivity. scanning electron microscopy is performed for the confirmation of durability claims. The analysis revealed that the use of produced PCA enhances the workability of concrete; nevertheless, the compressive and tensile strengths were reduced as 18.58% and 3.7%, respectively. PCA is treated with sand and silica fumes (SF) in order to attain targeted strength. It helped to reduce the negative effects of PCA on the strength properties of the concrete. PCA is concluded as a substitute for NCA having equivalent strength with enhanced performance of concrete.
