concreting purpose, especially as fine aggregates. In quarrying activities, the rock has been crushed into various sizes; during the process the dust generated is called quarry dust and it is formed as waste. Quarry dust should be used in construction works, which will reduce
crushed in a crusher unit for extraction of aggregates is left as fine dust and is considered to be waste. This fine dust is generally known as quarry dust. Quarry dust has particle size distribution close to that of sand. It is also found that utilization of quarry dust as fine
3.5 Quarry Dust: Quarry Dust can be defined as residue, tailing or o ther non-voluble waste material after the extraction and processing of rocks to form fine particles less tha n 4.75 mm. This product can be used for asphalt, substitut e for sand, and filling around pipes. Quarry dust can be an economic alternative to the river sand.
Coarse aggregates Fine aggregates The size of the aggregate bigger than 4.75 mm is considered as coarse aggregates and aggregate whose size is 4.75 mm and less is considered as fine aggregates. All aggregates are to be sampled properly before taking them for testing. The purpose of sampling is to get representative material for testing
quarry dust, which is a waste product from quarry, as fine aggregates in traditional concrete. During the tenure of the study, some physical and engineering properties of quarry dust and sand were determined and compared. The compressive strength of concrete was determined after replacing sand with quarry dust in various ratios.
The total substitution by volume of natural coarse calcareous aggregate by coarse recycled brick aggregate (RBA) and coarse recycled concrete aggregate (RCA) has been investigated to produce more sustainable and environment-friendly mortars. Aggregates were also partially substituted by their fines at 12.5% by volume. Mortars have been tested in terms of mechanical, microstructural, and

effect of quarry dust and sawdust, by adding 10%,15% and 20% with the fine aggregate, a matured fine aggregate has prepared. Vignesh b, Lingaraju D (Dec ). “Experimental study on partial replacement of quarry dust and saw dust in fine aggregate”. In this research was experimentally carried out to investigate properties of both sawdust and
The fine aggregates were graded in accordance with BS 812 part 1:1975. The coarse aggregate was crushed granite chippings of 20mm normal size and the cement conformed to BS 12. The river sand and the quarry dust used were those passing sieve 2 I I and retained on sieve 150𝜇 and the coarse aggregate (granite chipping) was passed through
and quarry dust as complete replacement for conventional river sand fine aggregate. The quantity of laterite was varied from 0% to 100% against quarry dust at intervals of 25%. Specifically compressive strength ranged from 17-34.2N/mm2 for the mixes considered. These results compare favourably with those of conventional concrete.
Crusher dust (quarry waste) is by product of stone crushers while producing coarse aggregate. Instead of disposing them in landfills, it can be best utilized as partial replacement to sand. In crusher dust, the particles (% finer than 150 microns) are generally high, a major concern limiting its percentage replacement to minimum with sand in a concrete mix.
Natural sand is most commonly used fine aggregates in the production of concrete possess the problem of acute shortage in many areas. Quarry dust can be used as an economic alternative to the natural sand. In this investigation an attempt is made to
This paper deals with the utilization of quarry dust in partial replacement of fine aggregate (sand), and ceramic waste in partial replacement of coarse aggregates in conventional concrete. The material properties of concrete that is compressive strength, split tensile strength and

Environmental Impact of Aggregates. Aggregates form the major part of concrete and are derived from many types of rock. Granite and limestone are extracted from quarries, crushed and graded. In many parts of the UK, land-based or marine sand and gravel are available: these require some processing, such as washing and grading, before use in
