Abstract
Concrete's widespread use in construction is accompanied by environmental concerns, including high carbon emissions from cement production and depletion of natural aggregates. This study explores self-curing concrete incorporating granite waste as a sustainable alternative. Self-curing concrete enhances hydration through internal curing agents like PEG 400, reducing external water curing needs. The research evaluates workability, mechanical properties, and durability by conducting compressive, split tensile, and flexural strength tests over 7, 14, and 28 days. Results indicate that replacing fine aggregates with granite waste improves strength characteristics. The addition of PEG 400 further enhances compressive strength, with a maximum of 39.5 Nmm at 28 days for 100% granite replacement. Similarly, split tensile and flexural strengths show significant improvement, with PEG 400-modified mixes achieving the highest values. The findings demonstrate that self-curing concrete with granite waste meets modern construction standards, offering an eco-friendly, durable, and high-performance alternative to traditional concrete.Keywords: Self-curing concrete, Granite waste, Compressive strength, Split tensile strength, Flexural strength, Sustainable construction.
