Concrete, known for its versatility and durability, is the material for construction that is most commonly utilised worldwide, comprising key ingredients such as cementitious materials, fine aggregate, coarse aggregate, and water. However, the growing demand for construction has necessitated the exploration of alternative materials that can replicate the performance of conventional components. This study focuses on the development of M-50 grade concrete using innovative substitutions to enhance sustainability and performance. The coarse aggregate is partially replaced with Bethamcherla stone in proportions of 10%, 20%, 30%, 40%, and 50% by weight. This stone, known for its unique characteristics, offers a potential alternative to traditional coarse aggregates, with an aim to improve resource efficiency. In addition to Bethamcherla stone, a self-curing agent, Polyvinyl Alcohol (PVA), is incorporated into the mix at 0.03%, 0.06%, 0.12% and 0.24% by weight of cement. PVA, known for its moisture retention capabilities, enhances the curing process by minimizing external water requirements, which is particularly beneficial in areas facing water scarcity. Furthermore, the study incorporates 10% silica fume, a highly reactive pozzolanic material, as a partial replacement for cement. Silica fume contributes to the development of a denser concrete matrix by improving the microstructure, ultimately increasing the concrete's compressive strength and durability. To evaluate the performance of this modified concrete, both fresh and hardened properties are analyzed. Fresh properties, such as workability and slump, are tested to ensure the concrete mix remains practical and easy to handle during placement. Hardened properties, including compressive strength and split tensile strength, are measured after 28 and 90 days of curing. These tests are crucial for understanding how the incorporation of Bethamcherla stone, PVA, and silica fume affects the long-term strength and performance of the concrete. This research aims to contribute to the development of sustainable, high-performance concrete by addressing key challenges such as resource conservation, water management, and material efficiency in construction practices.
