As the ability to use natural sand in cement mixtures declines, there has been an increased interest in the potential of quarry dust to replace it. Quarry dust is a waste product produced during the crushing process which is used to extract stone, and there is a great deal of it around, making it plentiful and cheap. The dust produced by quarrying has already been used in the construction industry for projects such as road building, and making materials such as bricks and tiles. The dust has been found to be suitable for these practices, and this makes its transformation into a useful cement mix replacement more likely.
