Sand is one of the important part in construction. The mining of sand also causes environmental problems which can affect the habitats and environment. The demand of sand makes the problem become very worst. To overcome this problem, partial replacement of sand can be done to reduce the amount of sand. In many country, quarry dust may become as the alternative choice to replace the sand

The replacement of natural fine aggregate by using quarry dust leads to consumption of generated quarry dust, the requirement of land fill area can be reduced and solves the natural sand scarcity problem. The sand availability as a fine aggregate at low cost which needs the reason to search as a alternative material.

Stone dust is also known as rock dust or quarry dust. As stone dust is the smallest form of crushed stone, it has a grading of 0-6. Two of the most common types of stone dust are granite and limestone typically used in preparing a concrete mix along with cement and aggregates for hardscape projects.

quarry dust as 100% replacement of river sand. Quarry dust can be described as the residue or tailing material after the extraction and processing of rocks and that forms fine particles less than 4.75mm. Quarry dust constitutes 20-25 % of the output of rubble crushing (Information gathered form the quarry owners).

fine aggregates in the production of concretes. Quarry dust, a by-product from the crushing process during quarrying activities is one of such materials. Granite fines or rock dust is a by-product obtained during crushing of granite rocks and is also called quarry dust. This present work is an attempt to use Quarry Dust as replacement for Sand.
