• <b>Sustainable Concrete Development: Performance Evaluation of Recycled Concrete Aggregate with Partial Replacement of Coarse Aggregate</b>
• <b>Project Overview:</b>
• Led a comprehensive research initiative focused on advancing sustainable construction practices through the innovative utilization of recycled concrete aggregate. The project systematically investigated the feasibility and performance characteristics of partially substituting natural coarse aggregate with processed recycled aggregate sourced from demolished concrete structures, contributing to waste reduction and resource conservation in the construction industry.
• <b>Key Responsibilities & Technical Contributions:</b>
• <b>Material Processing & Quality Control:</b> Executed systematic collection, crushing, and processing of demolished concrete waste to produce recycled coarse aggregate, implementing rigorous sieving and grading procedures to ensure compliance with standards for aggregate gradation
• <b>Mix Design Development:</b> Formulated and optimized concrete mix designs incorporating varying percentages of recycled concrete aggregate (10%, 20%, 30%, and 40% replacement ratios), maintaining consistent water-cement ratios and ensuring workability parameters
• <b>Laboratory Testing & Quality Assurance:</b> Prepared and cast standardized concrete test specimens (150mm cubes) following IS 516:1959 protocols, ensuring precise batching, mixing, and curing procedures for reliable test results
• <b>Performance Analysis & Data Evaluation:</b> Conducted comprehensive compressive strength testing at multiple curing intervals (7, 14, and 28 days) using calibrated compression testing machines, systematically comparing mechanical properties against conventional concrete benchmarks
• <b>Research Documentation: </b>Analyzed test data to determine optimal replacement percentages, documenting findings on strength development patterns, durability implications, and cost-effectiveness of recycled aggregate concrete for sustainable construction applications
• <b>Project Impact:</b>
• Demonstrated the technical viability of incorporating recycled concrete aggregate in structural concrete while promoting circular economy principles in construction, contributing valuable insights for sustainable infrastructure development.
