Possibility of using waste iron ore slag amp tiles as an alternative construction material will be investigated by conducting different tests on prepared specimens, it is 1.2 materials used the materials such as opc 53 grade cement sand coarse aggregate iron ore slag and mangalore tiles water
The other comprising granite stone as coarse aggregates. the compressive strength of bfs aggregate concrete is higher than that of the stone aggregate concrete at the age of 90 days. 1.3.slag- manufacturing and types in the production of iron, iron ore, iron scrap, and fluxes limestone andor dolomite are charged into a blast furnace along
Coarse aggregate coarse aggregate aggregates predominately retained on a no. 4 4.75-mm sieve are classified as coarse aggregate. generally, the size of coarse aggregate ranges from 5 to 150 mm. for normal concrete used for structural members such as beams and columns, the maximum size of coarse aggregate is about 25 mm.
In this project work, iron waste was collected from sohar steel plant and was mixed with concrete. the aim of this study is to determine the mechanical properties of concrete with iron waste to be compared with normal concrete. the percentages of iron waste can be added to concrete as 0, 10, 15 and 20 were based on literature review.
2. separation of the coarse aggregate from demolished waste takes time and labour. 2. literature review 1. use of demolished concrete waste in partial replacement of coarse aggregate in concrete ssrg international journal of civil engineering ssrg-ijce volume 3 in this paper, it is discussed that there is a large amount of

The utilization of waste as iron ore in making concrete aggregate quality k.300 concrete is an manmade building material that looks like stone. concrete is a composite material consisting of coarse-grained material aggregates or fillers that is embedded in a solid matrix of material cement or binder that fills the space between the ...
The iron ore tailings aggregates concrete exhibited a good mechanical strength and even in the case of compressive strength, there was an improvement of 11.56 over conventional aggregates concrete.
Iron ore waste as coarse aggregate in concrete as shown in figure 3, the slumps and liquidity of concrete mixed with iron ore tailings decreased compared with that of normal concrete under the same condition water, mixture ratio, admixture, etcthis phenomenon arises because the particles of iron ore tailings are rough and occluded with coarse ...
Hence the possibility of using waste iron ore slag amp tiles as an alternative construction material will be investigated. by conducting different tests on prepared specimens, it is intended to analyze the results. materials used the materials such as cement, sand, coarse aggregate iron ore
The replacement of coarse aggregate by tiles and sand by iron ore slag effects on the workability of the concrete. the workability of this proposed concrete shows an increase in slump with increase of waste content of total aggregate volume.
Ppts on iron ore waste as coarse aggregate in concrete download full text pdf. replacing aggregate coarse and fine with that of slag on various concrete properties. the a waste industrial byproduct of iron
Mechanical properties of concrete using recycled plastic concrete volume contains from 6580 aggregate and it plays a substantial role in concrete properties such as workability, strength, dimensional stability, and durability, so the use of waste materials in concrete as aggregates can effect in the amount of waste materials deeply.
Mangalore tile waste as coarse aggregate in concrete abstract. tile waste as coarse aggregate in concrete potential of using the broken clay tiles in concrete as an aggregate is studied in this study. a green approach is to use waste material in construction. today, alternative materials to replace constituent concrete materials are a hot ...
Of cement concrete when fine aggregate is replaced by iron ore tailings at different proportion. 1.3 scope of the project - the increasing demand for heavy construction material like steel and iron has resulted in the ent of many iron ore mining companies. iron ore tailings iot is the waste generated from iron ore
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.
The application of iots in concrete can fix the issues related to the management of waste residue of iron ore, and alleviate the increasing scarcity of natural aggregates.
Iron ore tailings which is the waste products of mining industries is used as an alternative to the river sand in the manufacturing of concrete. the kiocl company which was a leading company in india in the mining activities of iron ore has dumped about 200 million metric tons of iron ore tailings at lakya dam.
