EXPERIMENTAL INVESTIGATION OF CONCRETE BY USING EWASTE & MARBLE DUST

Abstract

The rapid increase in industrialization and electronic consumption has led to a significant accumulation of electronic waste (e-waste), posing severe environmental and disposal challenges. Similarly, marble dust, generated as a byproduct of marble cutting and polishing industries, creates ecological hazards when dumped indiscriminately. This study explores the sustainable use of e-waste and marble dust as partial replacements for conventional concrete ingredients. In this investigation, ewaste was incorporated as a partial replacement for coarse aggregates, while marble dust was utilized as a partial replacement for cement. Concrete specimens were cast and tested for compressive strength, split tensile strength, and flexural strength at varying replacement levels. The results indicate that a moderate percentage of e-waste and marble dust substitution enhances certain mechanical properties of concrete while contributing to waste minimization. Beyond performance, the approach promotes sustainable construction practices, reduces landfill burdens, and lowers the environmental footprint of concrete production. This experimental investigation demonstrates that integrating industrial byproducts into concrete can serve as an effective strategy for achieving both engineering efficiency and environmental sustainability.
