This document reviews 13 research papers on the use of e-waste as a partial replacement for aggregates in concrete. The key findings from the research papers are:
1) E-waste can partially replace both fine and coarse aggregates in concrete. Replacement levels of 10-15% of coarse aggregates and 5-10% of fine aggregates showed optimal compressive strengths.
2) Concrete with e-waste aggregates has lower density, making it suitable for producing lightweight concrete.
3) E-waste concrete exhibits better resistance to sulfate attack compared to conventional concrete.
4) Using e-waste aggregates in concrete provides an environmentally-friendly way to dispose of e-waste while reducing demands on natural resources.
