The performance of concrete using stone dust as a replacement to sand. Sand was replaced by quarry dust from 0 to at an increment of 25%. Compressive strength and tensile strength tests were conducted using 43 grade OPC in M20 concrete. Compressive strength was computed at the age of 7 days, 28 days, and 60 days.

Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world's use of aggregates for concrete can be estimated at 25.9 billion to 29.6 billion tonnes a year for 2012 alone.

Gravel Cost. One of the cheapest gravels available is quarry process, which costs, on average, $0.40 per square foot. At the other end of the price spectrum is marble chips. Expect to pay $2.00 per square foot for this high-end material. River rock is a little less expensive, averaging $1.50 per square foot.

The quarry sand is the coarse fraction of the quarry powder and is being used as the fine aggregate in place of river sand in concrete production [3]. The fine quarry dust fraction is commercially unused material [4]. Therefore, utilization of waste material quarry dust in the production of artificial aggregates is examined in this study.
