Nov 17, 2014 Through previous research we can also be made using iron as a replacement for the portion of either coarse aggregate or fine aggregate, these give even greater densities of 5900kg m3 for iron. Heavy weight or high density concrete can be designed in same way as normal weight concretes, but the additional self weight should be taken into account.Iron ore tailings are the waste generated from iron ore industry after process. It is a very fine aggregate residue resulting from the extraction of iron from iron ore. 3 METHODOLOGY- 3.1.1METHODOLOGY- Casting of cement concrete blocks with various proportion of iron ore tailing.
The iron ore based steelmaking (Fig. 1), which represents about 60-70 of the world steel production. The main raw materials are iron ore, coal, limestone and recycled It is used as material in cement, as fine aggregate for concrete and in civil engineering works, exhibiting better long-term strength, better resistance to chemical attack.Utilization of iron ore tailings as fine aggregate in. Iron ore tailings are a common and river sand has been employed successfully as a substitute for ITZ between cement paste and aggregate in concrete Know . Strength Analysis of Concrete by Using Iron Slag as a.
This research found that concrete using iron ore as an aggregate has a compressive strength higher than normal concrete that is equal to 38.90Mpa assuming greater size of iron ore as aggregate, the higher the Fe content, the size of escaped iron ore mesh aggregate 20, mesh 20 , mesh 5, 8-10 mesh and 10-12 mm mesh respectively 47,460 , 38,346.Coarse iron ore distributors in india. Concentration Iron Ore Mining River Sand As Coarse Aggregate. Iron ore . Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel98 of the mined iron ore is used to make steel.
Effect Of 87 Sand Equivalent On Fine Aggregates Using. Comparative Analysis of River Crushed Sand in Concrete ijirset. fine aggregate is the sand extracted from river banks. 2003 observe that concrete made using crushed rock attained a comparable and Raka 2004 studied the effect of varying replacement proportion of sand with quarry dust 20 30.May 21, 2013 iron ore tailings as fine aggregate. Shanghai Shibang Machine . is a high technology, engineering group. We are specializing in the research, development, and.
The increasing annual emissions of iron ore tailings have proved a great threat to the natural environment, and the shortage of natural river sand, as well as the pursuit of sustainable development materials, provides motivation to reuse iron ore tailings as a fine aggregate in concrete.In the present study Iron Ore Tailings (IOT) procured from Kudremukh Lakya Dam site (KIOCL Ltd.) are used as partial replacement to fine aggregates at levels of 10, 20,30,40,50 percent and the basic material properties, strength parameters are studied. It is found that as the IOT percentage increases in the mix workability is reduced.
Kumar et al. investigated the effect of partial total replacement of sand by iron ore tailing, as the fine aggregate on the compressive and flexural strength of reinforced concrete. The compressive strength was increased by up to 40 with the replacement of sand by iron ore tailing, while there was an enhancement of flexural strength for all.Use of Iron ore dust in concrete M as an alternative to normal aggregates. Conclusion. Clay tile chips can be used in concrete as a satisfactory aggregate to obtain good quality concrete and give strength. Replacing crushed stone aggregate (CSA) with clay tile chip aggregate (TCA) yielded a 7th day compressive strength of up to 14.2 N mm2.
Study on Utilization of Iron Ore Tailings as Fine Aggregates and GGBS as Partial Substitute in Concrete. Concrete with 25-30 of GGBS and mining waste (Iron ore tailings) instead of sand can be used as high strength concrete as it is giving strength than normal OPC concrete. Concrete with mining waste as fine aggregate and.The mix with only sand as fine aggregate served as the control mix, while sand was replaced in the other mixes by 20 , 40 , 60 , 80 and 100 iron ore tailing (IOT). Consistency and Strength test were conducted on both concrete specimens. It was observed that concrete workability reduced with increase in the percentage of iron ore tailing in.
The Influences of Iron Ore Tailings as Fine Aggregate on the Strength of Ultra-High Performance Concrete . By Zhigang Zhu, Beixing Li and Mingkai Zhou. Cite . BibTex Full citation Publisher Hindawi Limited. Year 2015. DOI identifier 10.1155 2015 412878. OAI identifier Provided by MUCC.The global financial crisis reached iron ore markets in September 2008. Prices of steel products and iron ore fell by up to 65 during the GFC. Thisprices in 2009 were led to long delays in resolving 2009 10 iron ore contract price negotiations. Prices were settled in July 2009 between the main iron ore.
Modulus of coarse aggregates was 6.95. The fine aggregate was natural sand of maximum size of 4.75mm. The specific gravity of fine aggregate was 2.54 and fineness modulus of fine aggregates was 2.62. Its grading confirmed to zone II. The Iron Slag was obtained from the Dhiman Iron and Steel industry located at Mandi.We are counted amongst the leading names of the company that is into offering Iron Ore. The products offered by us are of very fine quality. These products have rich content of iron as a result the users get relatively high amount of iron. Our products are very easily enriched as a result our clients save their precious time and money.
By complete replacing fine aggregate by Iron ore tailings, and GGBS as partial substitute to cement at 10 , 20 , 30 and 40 . The cubes were casted and their compressive strengths were evaluated at 7, 14 and 28 days. As the percentage increased the strength is also increased but only up to 30.2. Fine aggregate Two types of fine aggregates are used a) Steel slag as received from the factory without any screening b) Silica sand of natural resources known locally as desert sand. Sieve analysis was carried out on both the natural sand and the fine slag according to ASTM C33.Specific gravity and.
