Therefore, Quarry dust has been proposed as an alternative to the river sand in concrete mix, and it gives an additional strength to the concrete. This utilization of Quarry Dust by replacing sand would also reduce the pollution in environment and also reduce the cost of concrete. Keywords: - Quarry dust, Sand, Concrete, Compressive strength.

Use of substitutions like offshore sand in particular to replace river sand is on the rise. Quarry dust is another alternative for river sand. However, full replacement of river sand with quarry dust is viewed with scepticism. Possible loss of workability and increase shrinkage is sighted against use of quarry dust as fine aggregate in concrete.

LOGICAL ANSWER. To combat depleting natural sand and aggregate resources we should better utilise the abundant incoming CD&E waste stream. In its appraisal, concrete produced from recycled sand and aggregates is unfairly pitted against higher strength concrete produced using aggregates, such as granite or basalt, and natural sand.
