Experimental Evaluation of New-Generation Waste Material as a Substitute in M-50 Concrete Mixes

Abstract

The journey of concrete began around 600 BC, when the ancient Romans began widely using concrete for construction by mixing volcanic ash, lime, and seawater. Centuries later, it was in 1824 that Joseph Aspdin invented Portland cement by burning finely crushed chalk and clay until the carbon dioxide was eliminated. Between 1850 and 1880, Francois Coignet used Portland cement extensively for the first time in the construction of homes in England and France [17]. Since then, though there have been vast innovative leaps, improvements and inventions in the material used in construction, the construction industry is still heavily reliant on Portland cement and aggregates. This excessive use and mass dependence on concrete is now a concern for the construction industry as the natural resources used in concrete like sand and gravel are slowly being depleted. In addition, the environmental concerns relating to CO2 emissions from concrete have forced the industry to start looking for alternatives for the ingredients used in concrete.
 On the other hand, electronic waste, also known as electronic waste, is considered one of the harmful types of electronic waste in today’s new age world. Drinking water supplies are becoming polluted, and the environment and ecosystems are being impacted all around the world as a result of the unceasing increase of these technological wastes. Both of these current environmental issues can be mitigated to some extent by experimenting with and utilizing electronic waste materials in the construction industry. Along with traditional aggregate alternatives such as fly ash and rice husk ash, the industry is now experimenting with E-waste to determine if it can be a viable material for improving concrete strength and longevity.
 The primary objective of this research is to better understand the behavior of M-50 grade high strength concrete when coarse aggregate is replaced by E-waste plastics in staggered percentages. The strength of concrete containing E-waste plastic was tested at different time intervals after coarse aggregates were replacement with varying percentages of E-plastic waste by the volume range from 0 to 30 percentage. When compared to normal concrete, concrete with E-waste had comparable compressive, flexural, and tensile strength for 28 days up to a specified percentage of replacement. When the E-waste plastic component percentage is considerably high, however, there is a decline in strength after a certain point
