Abstract

This study focuses on the performance optimization of Dry Lean Concrete (DLC) by incorporating fly ash and recycled concrete aggregates (RCA) for rigid pavement applications. The increasing demand for sustainable construction materials and the need to reduce environmental impact have encouraged the use of industrial waste materials such as fly ash and construction waste in concrete production. In this research, Ordinary Portland Cement (OPC) is partially replaced with fly ash and natural coarse aggregates are substituted with recycled concrete aggregates in different proportions. Various mixes are prepared to evaluate the influence of these materials on the compressive strength and overall performance of DLC. Standard cube specimens of size 150 mm × 150 mm × 150 mm are cast and tested at different curing periods. The results indicate that the inclusion of fly ash improves workability and reduces water demand, while the use of RCA contributes to sustainable resource utilization. An optimum combination of fly ash and RCA shows improved compressive strength compared to conventional DLC. Additionally, the economic analysis reveals that the use of these waste materials can significantly reduce construction cost
