Jul 28, 2016 The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. By replacement of quarry dust, the requirement of land fill area can be reduced and can also solve the problem of natural sand scarcity. The availability of sand at low cost as a fine aggregate in concrete …

Published 2013. -The reduction in the sources of natural sand and the requirement for reduction in the cost of concrete production has resulted in the increased need to identify substitute material to sand as fine aggregates in the production of concretes especially in Concrete. Quarry dust, a by-product from the crushing process during quarrying activities is one of such materials.

investigated the partial replacement of sand with quarry dust. Initially cement concrete cube was studied with various proportions of cement concrete + quarry dust (M 20, AND M25). The experimental results showed that the addition of quarry dust as fine aggregate ratio of 30%, 40% and 50% was found to enhance the compressive properties.

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. In this study the properties of concrete with quarry

Abstract. This study tried to compare the flexural strength of concrete made with riversand and quarry dust as fine aggregate.River sand was collected from Osogbo, Osun State, replaced at 0-100% at intervals of 10% with quarry dust gotten from Wasimi, Osun State, Nigeria.Abstract Common river sand is expensive due to the excessive cost of transportation from natural sources.
