This research paper focuses on the shear behavior and strength characteristics of crushed rock fill materials, particularly decomposed rock fill materials used in high rock fill dams in India. The study aims to fill a research gap in the country by investigating the influence of particle size and crushing on shear properties. The Mohr-Coulomb failure theory is applied to analyze soil failure, considering shear stress, normal stress, and internal friction. The literature review highlights the potential of alternative materials like manufactured sand and crushed limestone in concrete applications for improved sustainability. The testing program involves direct shear tests on crushed limestone, sandstone, and river gravels at varying normal stresses. The results show that particle size impacts shear resistance, with larger particles exhibiting higher shear strength due to lesser breakage. The research offers valuable insights for dam design and construction in India and beyond, fostering sustainable practices in geotechnical engineering and construction.
