Quarry Dust. Quarry dust can be partially used as an alternative to river sand, as fine aggregate in concrete production. It is basically a by-product of stone crushers produced during the crushing and screening process of coarse aggregates. The replacement of river sand with quarry dust enhances the compressive strength of the concrete to a ...
The results concluded that the combinations of quarry dust and nickel slag in concrete as a whole substitution of sand provide similar results for these properties. Specifically, 25% quarry dust with 75% nickel slag proved to be the most promising alternative to sand, with compressive and splitting tensile strengths of 62 and 4.29 MPa ...
F.M of Ideal fine aggregate for concrete applications are in range of 2.6 to 2.9. Fine sand (lower F.M Value ) reduces the sand requirement % in the total aggregate proportion. On the other hand, coarser sand will require higher sand % in the total aggregate proportion to give a cohesive concrete mix consuming least cement.

durability studies of concrete made of quarry rock dust are nearly 10% more than the conventional concrete. Sahu, et al. (2003) reported significant increase in compressive strength, modulus of rupture and split tensile strength when 40 percent of sand is replaced by quarry rock dust in concrete. Nagaraj (2000) studied that
the target compressive strength by 12%. Both river sand concrete and quarry dust concrete for the selected water/cement ratio and mix ratio are suitable for non-structural applications and lightly-loaded members where high strength is not a prerequisite. Key words: density, compressive strength, concrete, river sand, quarry dust 1 Introduction
Quarry dust is one of the alternatives as it has some advantages over river sand such as better contribution to the strength of the cementitious material, better …
increased need to find new alternative materials to replace river sand so that excess river erosion is prevented and high strength concrete is obtained at lower cost. Partial or full replacement of natural sand by the other alternative materials like quarry dust, foundry sand and others are being researched from past two decades, in
This study presents the various properties of concrete with sand and its alternatives such as physical and mechanical characteristics of concrete. it is concluded that the highest substitute rate of sand replacement in concrete can help to resolve a variety of disposal-related difficulties, save the natural resources used in aggregate …
Sand collected from aeolian deposit is expensive due to unwanted cost of transportation from natural sources. Large scale exploitation of natural sand creates environmental impact on society. River sand is most commonly used fine aggregate in concrete but due to acute shortage in many areas, availability, cost & environmental …
Abstract- This experimental study presents the variation in the strength of concrete when replacing sand by quarry dust from 0% to in steps of 10%. M20 and M25 grades …
Hence, the proportion of concrete with lateritic sand and quarry dust is below 50% for construction purpose. Both flexural and tensile strength are increase with increase in lateritic
Treated Sea Sand (TSS) 25–100: Concrete with treated sea sand has a strength increase of 6.71% due to micro-organic matter and chloride removal. [15] …
To do so, the two types of sands used (Ebebda river sand and Leboudi quarry sand) were analyzed and proved to be clean and suitable for the implementation of all types of concrete with an sand ...
To overcome these problems there is a need of cost effective alternative and innovative materials. Quarry dust is a waste obtained during quarrying process. ... quarry dust concrete cubes of 150mm ...
River sand and lateritic soils were sourced locally around the Landmark University premise with a geographical position of 8.1239° N, 5.0834° E. Red earth soil (Fig. 1) was gotten at a location around a hilly terrain within the University premise while quarry dust (Fig. 2) was obtained from a quarry site within the township of Omuaran at a …
are forced to think of alternative materials. The Quarry dust may be used in the place of river sand fully or partly. A comparatively good strength is expected when sand is replaced partially or fully with or without concrete admixtures. ... Sand: Quarry dust concrete . International Journal of Scientific and Research Publications, Volume 3 ...
In such a situation the Quarry rock dust can be an economic alternative to the river sand. Quarry Rock Dust can be defined as residue, tailing or other non-voluble waste material after the ...
Quarry rock dust (QRD), a waste obtained during the quarrying process is a significant source of air pollution yet has the potential of becoming a sustainable and economical alternative to sand in concrete. Studies confirmed that replacing sand in …
