Nagamanib.(2008) concrete Strength and Durability Properties of Containing Quarry Rock. It can be concluded that the replacement of natural sand with Quarry Rock Dust, as full replacement in concrete is possible.
River sand is costly due to transportation, large scale depletion of resources and enforcement regulations. Quarry dust can be used as an alternative to the river sand. Cost analysis shows that there is 40% savings if quarry dust is used instead of sand. Illangoan.R1 [2000] has done a study on replacement of sand by quarry dust in …
In such a scenario, the rock quarry dust or quarry dust can be an associate degree in order to replace partially or fully river sand. Quarry dust is formed as a waste material which is non-voluble, residue tailing fine particles having size less than 4.75 mm. These are produced during process of processing and extraction of course aggregates.

for the effective material for replacing the river sand[22][23]. The crushed stone dust was not a new term, one of the waste materials which was obtained from stone crushers. The effective utilization of crushed stone dust for the replacement of natural river sand rectifying the land disposal problem, health and environmental hazards also [24].
The Fig. 4, shows that by replacing 25%, 50%, 75% and replacement of river sand with FAGS. From the Fig. 4, it can be observed that the compressive strength with zero FAGS (i.e. only river sand) was 16.1 MPa which decreased to 14.5 MPa at 25% replacement, 17.7 MPa at 50% replacement. It reduced to nearly 50% i.e. to 8.1 MPa …
In this paper study of M50 grade concrete consider a water cement ratio 0.37 for the hundred percentage replacement of fine aggregate (river sand) with steel fiber using Indian Standard method.
These alternative fine aggregate (AFA)/manufactured sand (MS) are generally produced from natural sources or any other sources like old concrete, rocks, industrial wastes after processing using thermal, mechanical and chemical separation, washing, crushing and scrubbing (Dash et al., 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 …
This Paper presents the practicability of using quarry rock dust as partial replacement for river or sharp sand using design mix of M20 grade concrete with replacement of 0 %, 20 %, 40...
It is clear that when the rock dust is included into UHPC to replace quartz sand, the flowability of UHPC can be slightly affected. For instance, when the quartz sand is replaced by rock dust by 0–60%, the UHPC flowability can exceed 300 mm. If the added rock dust is further increased, the UHPC flowability will generally reduce to about 295 mm.
80%, 90%, replacement of river sand with stone dust and immersed fully in potable water for curing and tested for 7 days and 28 days compressive strength.
This paper envisages use of m-sand as a replacement of river sand in concrete, and its advantages, disadvantages, applications and barriers on its use in India. ... Need for Manufactured Sands Natural sands such as river sand, marine sand, quarry dust and dune sand have their own drawbacks. For instance, marine sand has a high percentage of ...
Interesting trends for workability were observed with RCFA, granite dust, crushed rock, and RGA-used concretes reporting substandard performance. Nevertheless, the increase in the replacement level of river sand in RPA-used concrete resulted in increasing slump values, Declaration of competing interest
Quarry dust is a by-product from the crushing of hard rocks into aggregates of different sizes. The objective of this study was to determine the influence of quarry dust as a replacement...
Portland limestone cement, river sand and quarry rock dust both of 2 mm maximum size as ... about 5.4% in fl exural strength at sand replacement with quarry rock dust was recorded by Bakri ...
river sand, rock sand, quarry dust and material of quarry indicated SiO 2 +Al 2 O 3 +CaO ran ge of 84.3% - 92.5%, the three components impact on the setting time, early and final strengths and
Usually, natural river sand is used as a fine aggregate. However, places, where natural sand is not available economically, finely crushed stone may be used as a fine aggregate. 1.4QUARRY ROCK DUST: Quarry dust is the by-product which is formed in the processing of the granite stones which broken downs into the coarse

of concrete using varying combinations of lateritic sand and quarry dust as complete replacement for river sand. The study used mix compositions of 1:1:2, 1:1.5:3 and 1:2:4 with water/cement ratios of 0.5. 0.6 and 0.7. The results compared favourably with those of conventional concrete. Samples with 0 to 50% laterite
Several studies have been conducted in the past to investigate the effect of partial replacement of Natural River sand with crushed rock sand.
