(PDF) Stone Dust in Concrete: Effect on Compressive Strength

Granite fines or rock dust is a by-product obtained during crushing of granite rocks and is also called quarry dust. In recent days there were also been many attempts to use Fly Ash, an industrial by product as partial replacement for cement to have higher workability, long term strength and to make the concrete more economically available.

Jun 02, 2016· 1. Introduction. In many countries sources of natural sand for use as an aggregate in construction are becoming scarce as sand pits are exhausted and environmental legislation prevents dredging [1,2,3].This is driving the need to source alternative aggregates, such as those from construction and demolition waste.

The simple definition is that rock dust, also known as rock powder and rock flour, is pulverized rock. It can be man-made or occur naturally. Cutting granite for commercial use produces granite dust. Glaciers naturally produce glacial rock dust. Rock dust is also found near ancient volcanoes and consists of basalt rock.

Stone dust vs sand for laying pavers? Help!

replaced with stone dust (Franklin et al 2014). The compressive strength of concrete mix had increased by 22% with the use of crusher dust at 40% replacement of natural sand (Pofale et al 2013).The present study aimed to utilizing stone dust as fine aggregate in concrete in place of natural fine aggregate.

Rock Dust - Can It Remineralize the Earth? - Garden Myths

Stone dust, sometimes called rock dust, is a byproduct of crusher run that's provided the bedding layer for many a paver project over the years. While it can work in some construction applications, there's a growing recognition that sand – washed concrete sand in particular – has proven far more stable and exhibits properties that make ...

Use of Crushed Rock Sand - 3Dec07

There were in all 5 mixes in each grade of concrete including control mix and four mixes with crusher dust as a partial replacement of natural sand. It was observed that with use of crusher dust at all replacement levels, the workability of concrete was reduced from 1-6%.

COMPRESSIVE STRENGTH OF CONCRETE USING LATERITIC …

Quarry Rock Dust can be defined as residue, tailing or other non-voluble waste material after the extraction and processing of rocks to form fine particles less than 475mm Usually, Quarry Rock Dust is used in large scale in the highways as a surface finishing material and also used for manufacturing of hollow blocks and lightweight concrete.

Study on Compressive Strength of Quarry Dust as Fine ...

If having this done commercially, you are probably paying $3-7/SF for the concrete patio ($ difference depending largely local concrete/labor cost and accessibility) - redoing the base is probably about $0.50 or maybe $1/SF of that cosst, so not a major difference if in doubt, and cheaper than replacing a damaged slab a few years down the road.

THESIS A STUDY OF THE DURABILITY OF CONCRETE

Cost is an additional factor when deciding to use sand or stone dust, for both the short and the long term life of the project. Comparing the cost of stone dust to sand and estimating the likelihood of cracking will help you decide which to use. The color and texture of the product may drive your decision as well.

Effective Utilization of Crusher Dust in Concrete Using ...

Jul 01, 1996· If there is a reluctance to use crushed rock aggregates in concrete manufacturing, it is primarily based on this allowance of a higher dust content in crushed rock fines than that in the natural sand. Most of the crushed rock fine aggregate produced in N. Cyprus contains approximately 17 - 25% of dust.

concrete mix of 1:2:4 was used as control while sawdust was used to replace 25%, 50%, 75% and of sand by volume. The percentage reduction in density are 5.96%, 12.44%,13.56% and 17.93% respectively while the corresponding percentage reduction in

A Review on Green Concrete

5mm in size [24]. The use of quarry dust in concrete according to Chaturanga et al., [25] is desirable because of the benefits such as useful disposal of a by-product, reduction of river sand consumption and increase in strength. Quarry dust has rough, sharp and angular particles, and as such causes a gain in strength due to better interlocking.

EFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON …

For M20 grade and w/c 0.5, conventional concrete workability is found to be 0.95. For 20% quarry dust workability is 0.94. Further workability is decreased to 0.93 for 30% replaced concrete. For 40% quarry dust concrete workability is 0.90 and for 50% replacement of quarry dust concrete 0.89 compacting factor was observed.
