Is quarry dust suitable for block work?
Also, since quarry dust is quite fine, you should have a denser concrete. Higher density can mean less water penetration. The fine quarry dust particles will require more water to wet the greater surface area. More water causes weaker concrete. So, you should be using a water reducer - which will cost more.
