Quarry dust has the required properties of the river sand to be used as fine aggregate and has an equivalent usage in the concrete. The properties exhibited by the concrete made with Quarry dust as fine aggregate matches with the conventional concrete. 50 % of Quarry dust can be replaced in sand so
Apr 09, 2015· The results show that there is an increase in the compressive strength of the concrete [3,4] which the increment is about 55% to 75% depending on the replacement if the sand with the quarry dust ...
Sand was replaced by mass fractions of 0, 5, 10, 15, 20, 30 and 40% with granite dust. The study reflected that replacement of sand by granite dust up to 20% showed better strength than conventional concrete. The comparison study of bond strength with and without replacement of granite dust using different diameters of TMT bars was carried out ...
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 concrete ...
-The reduction in the sources of natural sand and the requirement for reduction in the cost of concrete production has resulted in the increased need to identify substitute material to sand as fine aggregates in the production of concretes especially in Concrete. Quarry dust, a by-product from the crushing process during quarrying activities is one of such materials.
Studies on quarry dust as partial replacement of fine aggregates in concrete Strength studies 5.1 Sieve Analysis The main objective of the investigation is to partially replace natural sand with quarry dust and study the behavior of concrete in the fresh and hardened state. The materials used for the investigation is first sieved and.
Concrete technology by Ms. SHETTY. and IS 456:2000. S.Subhashini on "use of quarry dust in concrete design".(2016) Praveen M (Feb 2014) Bijapur: Recent Trends in Replacement of Natural Sand With Different Alternatives''(IOSR-JMCE) e-ISSN: 2278-1684, pISSN: 2320-334X PP 59-6
From the experimental study, it is concluded that the quarry dust can be used as a replacement for fine aggregate. 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%.
50% manufactured sand, 35% waste foundry sand and 15% quarry dust. In the mix, the combined fine aggregate belongs to Zone II. The reason for the trend can be attributed to the presence of fine particles of waste foundry sand and quarry dust, which results in a denser concrete mix, and due to the presence of high silica content in
3.1.6 Quarry Dust: Quarry dust is a by product of the crushing process which is a concentrated material to use as aggregates for concreting purpose, especially as fine aggregates. In quarrying activities, the rock has been crushed into various sizes; during the process the dust generated is called quarry dust and it is formed as waste.
Previous research carried out on this shows positive results and hence quarry dust has very recently gained good attention to be used as an effective filler material instead of sharp sand. This project will investigate the effect of the total and partial replacement of sharp sand with quarry dust on concrete.
quarry dust as partial replacements for cement and sand when developing high quality concrete mixes. This study explores the strength behavior of concrete mixes with and without quarry dust. The various percentage of quarry dusts such as 10 percent to 45 percent were used to partially
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.
To overcome this problem, present study is focused on the suitability to utilize the quarry dust in Self Compacting Concrete (SCC) partially as fine aggregate with the natural fine aggregates. In this work, quarry dust is used as replacement of sand in a different level (0%, 15%, 30%, 45% and 60%) for producing the SCC.
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.
attempt to partially replace quarry dust + red soil in place of sand in M20 grade concrete. On experimentation, it was found that the partial replacement of sand with 20%, 30%, 40%, 50% of quarry dust + red soil has given the optimum results. Therefore, this study recommends that if partial
The study has conducted to determine the workability and compressive strength of the self –compacting concrete. The sand has replaced with quarry dust with the proportion of 10, 20, 30 and 40% ...
Parametric Study for Replacement of Sand by Fly Ash for Better Packing and Internal Curing ... Flexural Behavior and Impact Strength of Ferro Cement Slabs Reinforced with PVC Coated Welded Mesh with Addition of Waste Plastic Fibre ... Experimental Investigation on Partial Replacement of Cement by Fly Ash and Sand by Quarry Dust
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 of concrete were taken for study keeping a constant slump of 60mm.
BEHAVIOUR OF CONCRETE ON THE USE OF QUARRY DUST TO REPLACE SAND - Free download as Powerpoint Presentation (.ppt / .pptx), PDF File (.pdf), Text File (.txt) or view presentation slides online. To use of the quarry dust replacement of fine aggregate reduces the environmental pollution as well as providing an economic value for the waste material.
Three replacement levels of 0%, 25% and quarry dust were used in the concrete mixes. The 25% is the optimum replacement percentage achieved by carrying out strength studies for 0%, 25%, 50%, 75% and sand replacement levels.
The results of the study also indicates that quarry dust can be utilised as partial replacement material to sand, in the presence of silica fume or fly ash, to produce concretes with fair ranges ...
dust as fine aggregate is studied to find out its suitability to replace river sand in structural concrete. Furthermore, use of fly ash with 30% of cement replaced by fly ash is explored as means of increasing the performance of the quarry dust mixes. Quarry dust concrete at the tested water cement ratio is
(Olamalocality, Center, Cameroon) and with quarry sand (SG) from Koulouganga (Center, Cameroon). Secondly, these concretes properties were compared to a concrete formulated from the mixture of alluvial sand (SN) and quarry sand, which was denoted MS. Three types of formulations were performed with the same gravels, constant cement dosage and
