Utilization Of Kota Stone Slurry Powder and Recycled Aggregate for Rigid Pavement

Abstract

This research paper highlights the use of waste materials such as recycled coarse aggregate (RCA) and stone slurry powder (SSP) in the production of concrete, which offers significant environmental and economic benefits. The aim of this study was to investigate the impact of substituting cement with SSP on the consistency, initial and final setting time, and strength properties of concrete, as well as replacing natural coarse aggregate (NCA) with RCA and cement with SSP on the fresh and hardened properties of concrete. The experimental results showed that the substitution of cement with SSP and NCA with RCA improved the compressive strength, split tensile strength, and flexural strength of the concrete. This research contributes to sustainable construction practices by providing an alternative to depleting natural resources and reducing waste generation from stone-cutting activities. The findings of this study suggest that using SSP and RCA in concrete production has the potential to reduce the environmental impact of the construction industry while also providing a cost-effective and sustainable alternative to traditional concrete production methods. However, the use of SSP resulted in a decrease in slump, which may require more water and absorb water from the mix, leading to reduced workability. Therefore, further research is needed to investigate the long-term durability and sustainability of concrete made with SSP and RCA. In conclusion, this study demonstrates the potential for using SSP and RCA as alternative materials in concrete production to achieve stronger, more sustainable, and cost-effective construction.
