Jun 02, 2016· The average values represent the properties of a fine aggregate which could be encountered and could be a 50:50 blend of dredged natural sand and clay contaminated quarry dust mixed in concrete with medium dosage of plasticiser and w/c ratio of 0.62.

alternative material to natural sand. Some alternatives materials have already been used as a replacement of natural sand such as fly-ash, quarry dust or limestone and siliceous stone powder, filtered sand, copper slag are used in concrete and mortar mixtures as a partial or full replacement of natural sand (Chandana Sukesh et al 2013)[9].

investigated the partial replacement of sand with quarry dust. Initially cement concrete cube was studied with various proportions of cement concrete + quarry dust (M 20, AND M25). The experimental results showed that the addition of quarry dust as fine aggregate ratio of 30%, 40% and 50% was found to enhance the compressive properties.

It is good to be creative and to think outside the square. However there are sometimes that things have been done a certain way for a long time for a good reason. The problem is that using what I would call "crusher dust" or "crusher fines" will ...

clear picture that quarry dust can be utilized in concrete mixtures as a good substitute for natural river sand giving higher strength at 50% replacement. Index Terms- Concrete, quarry dust, river sand, compressive strength. I. INTRODUCTION oncrete is the most widely used composite material today.

2.4 QUARRY DUST (QD) Quarry dust is fine rock particles. When boulders are broken into small pieces quarry dust is formed. It is grey in colour and it is like fine aggregate. In concrete production it could be used as a partial or full replacement of natural sand. Besides, the utilization of quarry .

This paper deals with replacement of sand used in concrete as fine agg. regates by the waste generated by the stone quarry industry. This study has made . an attempt to partially replace quarry dust in place of sand in M35 grade concrete. On experimentation, it was found that the. partial replacement of sand . with. 10% of quarry du. st. has given

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 ...

Improved Concrete Properties Using Quarry Dust as Replacement for Natural Sand Anzar Hamid Mir Student, Bachelor of Civil Engineering, IUST Awantipora, J&K, INDIA Abstract:- Concrete plays a major role in the construction industry. Natural sand is a prime material used for the preparation of concrete and also plays an important role in Mix Design.

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 cost as a fine aggregate in concrete is not suitable and ...

The effect of quarry dust on the flexural strength of concrete has been experimentally studied and reported in this paper. Concrete used was prepared by replacing 25% and of sand by weight with quarry dust.

This paper presents the feasibility of the usage of Quarry Rock Dust as hundred percent substitutes for Natural Sand in concrete. Mix design has been developed for three grades using design an approach IS, ACI, USBR, RN.No.4 and BRITISH for both conventional concrete and quarry dust concrete.

of cement content, workability, compressive strength and cost of concrete made with Quarry Rock Dust . Ilangovan (Studies on Strength and Behavior of Concrete by using Quarry Dust as Fine Aggregate) reported that Natural Sand with Quarry Dust as full replacement in concrete as possible with proper treatment of Quarry Dust before utilization .

grades of concrete by replacement of sand with quarry dust. Key Words: Concrete, Compressive strength, Quarry Dust, Replacement, Sand. 1. INTRODUCTION Quarry dust, is a by-product releases from the cutting and crushing process of stone which is a concentrated material to use as fine aggregates. By exploding mountain, rock will be crushed to

The dust has been found to be suitable for these practises, and this makes its transformation into a useful cement mix replacement more likely. Quarry Dust and Cement Mix. Recent research into the potential of quarry dust in cement mixes have focused upon a partial replacement of the sand. The results to far suggest that a cement mix made of ...

but quarry dust is useful for construction work as sand. If we mix quarry dust in sand then only 65% to 75% of sand replaced by quarry dust because strength of concrete is affected by this process. In other process if we mix quarry dust and fly ash are added together in concrete mix then we

The effect of quarry dust on the flexural strength of concrete has been experimentally studied and reported in this paper. Concrete used was prepared by replacing 25% and of sand by weight ...

to study the effect of partial replacement of fine aggregates by quarry dust and cement by fly ash on cement concrete. 1.2 NEED FOR INVESTIGATION Quarry Dust These residues are generally less than 1% aggregate production in the normal concrete. The introduction of quarry dust for mixing is limited due to its high fineness.

of quarry dust and the suitability of those properties to enable quarry dust (Celik et.al.,) to be used as partial replacement material for sand in concrete. The use of quarry dust in concrete is desirable because of its benefits such as useful disposal of by products, reduction of river sand consumption as well as increasing the strength

Suitability of Quarry Dust as Partial Replacement Material for Sand in Concrete ... There are other studies related to analysis of influence of tailings and/or quarry dust in concrete and are also ...

Quarry rock dust can be an economic alternative to the river sand. Quarry Rock Dust as substitutes for Natural Sand in concrete. Mix design has been developed for M25 and M40 grades using design approach IS for both conventional concrete and quarry dust concrete.

For 40% quarry dust concrete workability is 0.90 and for 50% replacement of quarry dust concrete 0.89 compacting factor was observed. quarry dust tested for 3 days, 7 days, and 28 days is studied For M25 grade and w/c 0.5, conventional concrete work- and the results are presented.

Concrete without sand? ... Journal of Innovative Technology and Exploring Engineering in May 2013 says that the ideal percentage of the replacement of sand with the quarry dust is 55 per cent to 75 per cent in case of compressive strength. He further says that if combined with fly ash (another industrial waste), 100 per cent replacement of sand ...
