Quarry dust concrete at the tested water cement ratio is found to have higher compressive strength compared to sand mixes. However, use of quarry has increased the required amount of water in the mix to achieve the design slump. It is also found that the quarry dust mixes has higher shrinkage strain compared to sand mixes.
