Suitability of Quarry Dust as a Partial Replacement of Fine Aggregate in Self Compacting Concrete

Abstract

Large quantity of the quarry dust gets produced annually in the quarries during the extraction of the crushed coarse aggregate. As a result, disposal problems of this material gain significant momentum as these disturb environmental systems also. Now-a-days many of the countries like India is facing problems of ban on the extraction of sand and lacunae in procuring of fine aggregate, which is important constituent of the concrete. To overcome this problem, present study is focused on the suitability to utilize the quarry dust in Self Compacting Concrete (SCC) partially as fine aggregate with the natural fine aggregates. In this work, quarry dust is used as replacement of sand in a different level (0%, 15%, 30%, 45% and 60%) for producing the SCC. Fresh properties such as slump flow and V-funnel time have been measured for all mixes and hardened properties as compressive strength, splitting tensile strength and flexural strength of the concrete have been checked for all the mixes and it has been found that optimum utilization of quarry dust up to 30% can been done to produce SCC without compromising with its properties.

Partial Substitution of Cement and Fine Aggregate with Waste Paper Sludge Powder and Quarry Dust in Enhancing the Strength Parameters of Concrete

“…Mundra S, et.al prepared concrete mixes to measure compressive strength in the presence of Quarry dust which has different proportions, and found that 30% replacement has higher strength [15]. Arpitha D, et.al performed the experiment on a different percentage of quarry dust and found that at 15% replacement compressive strength increased by 2% [16].…”
