The significance of this research is to resourcefully use E-waste in concrete by achieving optimum performance by testing physical, workability & mechanical properties. The E-waste generated at Pillai HOC College of Engineering and Technology (PHCET), Rasayani was used as partial replacement of coarse aggregate (CA) in combination …

For solving the disposal of large amount of E-waste material, partial use of E-waste in concrete industry is considered as the most feasible application. The e-waste like non-metallic parts of PCB plates can be recovered and can be used as an ingredient in concrete. So we can use this e-waste to achieve desire concrete in terms of their …

To sustain the environment, it is crucial to find solutions to deal with waste, pollution, depletion and degradation resources. In construction, large amounts of concrete from buildings' demolitions made up 30-40 % of total wastes. Expensive dumping cost, landfill taxes and limited disposal sites give chance to develop recycled concrete.

Above graph shows the strengths of E-waste plastic concrete with mixing ratio of E-waste plastic aggregate. x The compressive strength values of all waste plastics concrete mix tend to decrease below the values for the reference concrete mixtures with increasing the waste plastic ratio at all curing stages. This may attribute to the decrease …

Efforts to increase the use of recycled plastics worldwide aim to address the hazardous consequences of improper plastic treatment. One potential solution is incorporating plastics as binder or mixture modifiers in asphalt concrete (AC) mixtures, which repurposes waste plastics while reducing environmental impacts related to AC …

So, there is a need to produce alternative cement instead of ordinary Portland cement (OPC). Waste materials such as sugarcane bagasse are difficult to dispose which result in environmental hazard. This study investigates the use of sugarcane wastes in concrete, where two forms of sugarcane wastes were used in this study.

Waste E-plastics on the other hand, are materials which cannot be recycled. Therefore, a study on characteristics of concrete having E-plastics as a replacement to fine aggregate is conducted and applications are suggested. In this research work, a survey was conducted to quantify the amount of waste E-plastic generated per day.
