Abstract
his study examines the impact of partially substituting cement in concrete with marble powder at varying percentages (0% to 50% by weight). The objective is to understand how marble powder influences the performance of concrete, specifically regarding its mechanical properties and workability. A total of twenty concrete mixes were developed using two types of cement: ordinary Portland cement and sulfate-resistant Portland cement. Each mix was evaluated for a range of properties, including slump, water absorption, density, compressive strength, splitting tensile strength, and flexural strength. The results are expected to provide insights into optimizing the use of marble powder as a sustainable alternative. By promoting the incorporation of waste materials like marble powder, this research supports the construction industry's transition towards more eco-friendly practices. Ultimately, the findings aim to contribute to the development of innovative, environmentally friendly construction materials that can reduce the ecological footprint of concrete production while maintaining high performance.
