This paper reviews the use of quarry dust as a partial replacement for sand in concrete mixes. River sand is commonly used as a fine aggregate in concrete but its availability is decreasing due to overuse. Quarry dust is a byproduct of the quarrying process and has been proposed as an alternative to river sand in concrete. The paper evaluates past research on replacing sand with quarry dust up to percentages of 50-75% by weight. Studies have shown that replacement of up to 50% sand with quarry dust can increase the compressive strength of concrete. Using quarry dust could help address shortages in river sand while reducing pollution and construction costs. The paper concludes that partial replacement of sand with quarry dust in concrete
