Abstract
"A Study on Sandstone Quarry Dust" is a study focused on investigating the use of sandstone quarry dust as a partial replacement for natural sand in concrete. The study aims to address issues related to excessive sand mining and environmental impacts, while exploring quarry dust as a sustainable alternative for natural sand in construction.The research tests concrete mixes with different substitution rates of sandstone quarry dust (10%, 20%, 30%, 40%, and 50%) and evaluates various properties, including workability, compressive strength, tensile strength, water absorption, chloride-ion permeability, and durability. The study also conducts X-ray diffraction (XRD) and scanning electron microscope (SEM) analyses to observe changes in cement phases and microstructure.Key findings highlight that quarry dust can improve concrete properties under specific conditions. This concludes with recommendations for optimal substitution rates to balance strength, durability, and workability, presenting sandstone quarry dust as a viable partial replacement for natural sand in concrete production. The study investigates the potential of using sandstone quarry dust as a sustainable partial replacement for natural sand in concrete. This research aims to mitigate the environmental impacts of excessive sand mining by exploring alternative materials. Results indicate that replacing natural sand with quarry dust can improve certain properties of concrete, especially with an optimal replacement level around 40%. The study concludes that sandstone quarry dust is a viable, environmentally friendly alternative for partial sand replacement in concrete, with minimal impact on workability and significant improvements in density, strength, and durability under specific conditions.Keywords: Stone dust, Concrete mix, Sand replacement, Compressive strength, Workability, Portland Composite Cement (PCC), River sand, Waste management, Slump test, Sustainable concrete materials
