Get PriceBoth river sand concrete and quarry dust concrete for the selected water/cement ratio and mix ratio are suitable for non-structural applications and lightly-loaded members where high strength is not a prerequisite. This study compared the physical and mechanical properties of river sand concrete with quarry dust concrete. The constituent materials were batched by weight. The water-cement ratio
Get PriceTherefore, 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.
Get PriceMar 15, 2021· The quarry dust concrete and river sand concrete shoed slump test values of 80 mm and 60 mm, respectively. And, fresh concrete mix of quarry dust concrete showed lower workability than river sand concrete for 1:2:4 mix ratio and water-cement ratio of 0.55. The higher slump interposed for quarry dust may be due to higher sand content in quarry dust.
