Quarry process, also known as QP, dense grade aggregate (DGA), crusher run and road stone, is a combination of small, 3/4-inch-or-less crushed stone and stone dust. Most often it is made out of crushed limestone, granite-gneiss, trap rock or a combination of the aforementioned.
The compressive strength of concrete with quarry dust has 40% more strength than that of the concrete with sand. M. Shukla and A K Sachan (2000) studied environmental hazardous stone dust utilization in building construction. It is found that partial replacement will not affect the strength and also solve the problem of disposal of stone dust.
Initially cement concrete cube was studied with various proportions of cement concrete + quarry dust (M 20, AND M25). The experimental results showed that the addition of quarry dust as fine aggregate ratio of 30%, 40% and 50% was found to enhance the compressive properties.
Granite fines or rock dust is a by-product obtained during crushing of granite rocks and is also called quarry dust. In recent days there were also been many attempts to use Fly Ash, an industrial by product as partial replacement for cement to have higher workability, long term strength and to make the concrete more economically available.
