Abstract
The construction industry plays a pivotal role in global development, but its environmental impact is profound due to resource consumption and waste generation. This study investigates the viability of integrating marble dust and rice husk ash (RHA) as partial replacements for cement in concrete production, aiming to mitigate environmental burdens while enhancing sustainability. The research evaluates mechanical properties, durability, and sustainability advantages of the resultant green concrete. Utilizing waste materials not only addresses environmental concerns but also aligns with the industry's evolving sustainability agenda. The study employed a comprehensive methodology, adhering to established standards and protocols. Ordinary Portland Cement (OPC), natural sand, crushed stone aggregates, marble dust, and RHA were utilized as materials. Various tests, including compressive strength, water absorption, permeability, and slump, were conducted to assess concrete properties. Concrete samples were fabricated, cured, and tested according to Indian Standard specifications. The investigation revealed promising outcomes regarding the mechanical properties of green concrete. Compressive strength tests demonstrated improvements with the inclusion of marble dust and RHA, particularly at a 15% replacement level. Durability assessments indicated reduced water absorption and permeability, suggesting enhanced resistance to environmental factors. Slump tests revealed varying workability across replacement levels, emphasizing the importance of careful mix design. The findings of this study hold significant implications for sustainable construction practices. Integrating waste materials like marble dust and RHA into concrete production not only enhances performance but also reduces reliance on virgin resources. The sustainability benefits extend to environmental conservation, resource efficiency, and carbon footprint reduction. Implementing these findings in construction projects can contribute to a more sustainable built environment, aligning with global sustainability goals.
