Study on Compressive Strength of Quarry Dust as Fine
For 25% quarry dust, the value increased to 30.81 N/mm 2. Finally, for 30% quarry dust, the strength increased to 32.88 N/mm 2. Hence, quarry dust can be effectively used to replace natural sand, without reduction in the strength of concrete. The slight variation is observed in compressive strength for 3 days' and 7 days' age in concrete.
