Quarry Dust as a Partial Replacement of Coarse Aggregates in Concrete Production Aginam C. H1. Nwakaire, C2., Onah, B. C3. 1,2,3Department of Civil Engineering, Nnamdi Azikiwe University, P.M.B. 5025, Awka Abstract: This study is an attempt to investigate the suitability of quarry dust as a partial replacement ofWhat are the advantages of using quarry dust as fine,,It is found that 40% replacement of sand by quarry dust gives maximum result in strength compared to normal concrete and then decreases from 50%. The results proved that up to 40% replacement of sand by the quarry dust induced higher compressive strength and the workability of concrete decreases as replacement increases.Improved Concrete Properties Using Quarry Dust as,,quarry dust was taken. The workability of the concrete is decreasing when the replacement percentage of the quarry dust is increasing gradually; so as to increase the workability small quantity of the fly-ash is replaced in place of cement to increase the workability [2].

EFFECT OF WATER CEMENT RATIO ON THE WORKABILITY

concrete with water cement ratio 0.5. All mixes of Quarry dust concrete with w/c 0.5 gave poor quality mixes (CF below 0.85) while all mixes of quarry dust concrete with w/c 0.65 gave good quality mixes(CF between 0.92 and 0.97). All the other mixes of quarry dust concretequarry dust cement ratio in concrete-DBM Crusher,2016-4-10 · (c) The compressive strength results of quarry dust concrete (cubes) were obtained in the third series, where M20, M25, and M30 grades of concrete with 20, 25, and 30 percent replacement of quarry dust and also workability are studied by varying the water-cement ratio of 0.45 and 0.50 and the results are presented.Compressive strength and workability of laterized quarry,,For each mix and water/cement ratios, control samples were also prepared using river sand as fine aggregate. The resulting concrete cubes fall within the range for normal weight concrete and although laterized quarry dust concrete had poorer workability, their compressive strength compare favourably with those of conventional concrete.

EXPERIMENTAL INVESTIGATION ON QUARRY DUST

on the mechanical properties of concrete with quarry dust. They reported that the quarry dust may be used as an effective replacement material for natural river sand which increased the strength. Ilangovana. R et al. carried out an investigation on strength and durability properties of concrete containing quarry rock dust as fine aggregate.Behaviour of Concrete on the Use of Quarry Dust and,,quarry dust for the same w/c ratio. Concrete does not give adequate workability with increase of quarry dust. It can be due to the extra fineness of quarry dust Increased fineness require greater amount of water for the mix ingredients to get closer packing, results in decreased workability of the mix. The above slump valueQuarry Dust | Concrete | Construction Aggregate,Split tensile strength of quarry dust concrete and addition of 10% silica fume is more than the conventional concrete Flexural strength of quarry dust concrete and addition of 10% silica fume is more or less equal to conventional concrete.
