The present study aims to investigate the potential of marble dust to enhance the strength of soils for possible use as a subgrade material. Two different types of soils are amended with varying marble dust (MD) content (0–100%) in order to examine its effectiveness in improving the subgrade properties (i.e. strength and stiffness). The subgrade properties of sandy soil (SS) and black cotton

Quarry dust is a waste obtained during quarrying process. It has very recently gained good attention to be used as an effective filler material instead of fine aggregate. Also, the use of quarry dust as the fine aggregate decreases the cost of concrete production in terms of the partial replacement for natural river sand.

Stone dust is also known as rock dust or quarry dust, and some products just have the brand name. The stone dust is collected using a screen that keeps the larger pieces of crushed stone above the screen while allowing the rock dust to fall through. This process is the reason why stone dust is often called quarry screenings.

The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. By replacement of quarry dust, the requirement of land fill area can be reduced and can also solve the problem of natural sand scarcity. The availability of sand at low cost as a fine aggregate in concrete is not suitable and

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.
