Performance Of Concrete With Quarry Dust As Fine Aggregate

Chapter 2 literature review 2.1 general this chapter presents an overview of literature on the various experiments conducted by many authors on the replacement of fine aggregate by quarry dust, manufactured sand and the results thereof highlighting the significance of using the manufactured sand for replacing the natural sand in concrete.

The analysis shows that it is more economical to produce grade 40 concrete with a combination of 80 sand plus 20 cgf as fine aggregate, using gravel as coarse aggregate, at a cost of n16, 602 per cubic metre, than the cost of n 17,293 per cubic metre obtained when only makurdi river sand was used as fine aggregate and gravel as coarse.

Unlike other waste by products quarry dust is the waste material found from the crushing process of the stones and available abundantly from rock quarries at low cost2.Quarry dust may cause negative impact on environment 3.Quarry dust has partially replaced with fine aggregate in concrete and significant improvement has witnessed 4, 5.

Feasibility of quarry dust to replace river sand as fine.The quarry dust mixes has higher shrinkage strain pared to sand mixes use of fly ash in quarry dust mixes is found helpful in reducing the shrinkage of quarry dust concrete results indicate that quarry dust can be effectively used to replace sand and fly ash can improve the performance of concrete with quarry dust as fine aggregate.

Application of quarry dust in concrete constructionflat.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.

Crusher dust concrete work schoolpartnernl crusher dust as fine aggregate in concrete work possibility of using crushed stone dust as fine aggregate partially or fully with performance of concrete, so fine aggregate is an essential working out a inquiryexperimental investigation on concrete ,.

Concrete and compared with the natural sand concrete.They found that the compressive, split tensile strength and the durability concrete were good when the fine aggregate was replaced with 50 marble sludge powder and 50 quarry rock dust green concrete.The resistance of concrete to sulphate attack was enhanced greatly.R.Iiangovana.

And durability properties of concrete containing hundred per cent quar ry dust as f ine a ggrega te w as studied 3,4.They conc luded that strength properties of concrete made of quarry dust are nearly 10 more than conventional concrete.The use of quarry dust as fine aggregate in concrete will reduce not only the demand.

Quarry dust as a fine aggregate in concrete la.Requirement, workability, compressive strength and the cost of quarry dust concrete have been studied in the.Quarry dust being a generated material rather than a natural aggregate is well graded and has a rougher surface texture due to crushing.

This paper presents an investigation on the flexural behavior of high performance concrete beams produced from metakaolin, sea wage and quarry dust, m-sand is an economic alternative to the river sand.In this investigations metakaolin, as partial cement replacement and quarry dust, m-sand as partial fine aggregates replacement.

Was studied with various proportions of quarry dust cm 13, cm 12, and cm 11.The experimental results showed that the addition of quarry dust for a fine to coarse aggregate ratio of 0.6 was found to enhance the compressive properties as well as elastic modulus.Key words concrete, quarry dust, fillers, elastic modulus, compressive strength.

The most commonly used fine aggregate across world is river sand.River sand is expensive due to excessive cost of transportation from natural sources.Also large scale depletion of the source creates environmental problems.As environmental, transportation and other constraints make the availability and use of river sand less attractive.A substitute or replacement product for concrete.

The flexural strength of concrete made with quarry dust as fine aggregate is higher about 4.3 than conventional river sand concrete.2.The 1015 rule of thumb was found to be applicable in the estimation of flexural strength of quarry-sand concrete based on its compressive strength.3.

The research focuses on the effect of using waste marble powder and quarry dust as partial sand replacement materials on concrete properties.Massive exploitation of the nonrenewable natural resources to fulfill the aggregate requirement of billions of tones each year for concrete production bears the serious risk of their gradual depletion.

From the above study, it is concluded that the quarry rock dust and marble sludge powder may be used as a replacement material for fine aggregate.The replacement of fine aggregate with 50 marble sludge powder and 50 quarry rock dust green concrete gives an excellent result in strength aspect and quality aspect.

Concrete, their availability is continuously being depleted due to the intentional overexploitation throughout the globe.Hence, partial or full replacement of fine aggregates by the other compatible materials like sintered fly ash, crushed rock dust, quarry dust, glass powder, recycled concrete dust, and others are being researched.

Free online library studies on pumice lightweight aggregate concrete with quarry dust using mathematical modeling aid of aco techniques.Research article by advances in materials science and engineering engineering and manufacturing concrete analysis mechanical properties methods usage concretes mathematical optimization optimization theory.

Corrosion resistance properties of concrete in which fine aggregate is fully replaced by quarry dust and cement is partially replaced by 10, 20, 30, 40 and 50.The resistance to corrosion is evaluated based on the performance of the concrete for penetration of chloride ions.

The quarry dust mixes has higher shrinkage strain compared to sand mixes.Use of fly ash in quarry dust mixes is found helpful in reducing the shrinkage of quarry dust concrete.Results indicate that quarry dust can be effectively used to replace sand and fly ash can improve the performance of concrete with quarry dust as fine aggregate.

Present investigation aimed at to study, 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100 of traditional fine aggregate was replaced with quarry dust and coarse aggregate was replaced with blast furnace slag.Compressive strength, split tensile strength and flexural strengths were found after 7 days and 28 days of curing.

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 prefabricated elements.Use of quarry rock dust as a fine aggregate in concrete draws serious attention of researchers and investigators.
