Yes, correct.

Sand can be replaced by Quarry dust without any problem.

• Based on several references, I concluded that sand can be replaced by Quarry dust without highly compromising its durability property.
• By the experimental investigation, 40% replacement of sand with Quarry dust shows maximum compressive strength and later on, it will decrease after increasing percentage of Quarry Dust in the sand.
• Workability of concrete decreases as increasing the percentage of Quarry dust
• Quarry dust is Waste. If we use quarry dust as a replacement of sand, then waste will ultimately reduce.
