Sustainable use of mine waste and tailings with suitable
Sustainable use of mine waste and tailings with suitable The literature shows the potential use of iron ore tailings as a replacement of natural fine aggregates As natural sand reserves are d • Substrate for revegetation at mine sites • Aggregate in embankment, road, rich mine tailings Concrete is a mixture of cement, sand (fine aggregate), small stone or gravel (coarse aggregate) and water while mortar is a mixture of cement, sand (fine aggregate), and water More specifically, this study is assessing the mechanical behaviour Use of mine tailings as raw material in concrete and Often tailings are relatively fine, with sand being the high end and slimes the fine fraction Depends on the age and type of process A hundred years ago, many had coarse fractions of 3/8" or so, but the tails are pumped or sluiced, so aggregate doesn't much fitMine Tailings as Aggregate Concrete Engineering general

Stabilization characteristics of copper mine tailings
This paper presents the feasibility of incorporating copper mine tailings (MT) as a partial substitute for cement in the development of concrete The copper mine tailings used for this study have been accumulating for several decades at the tailings dump of Hindustan Copper Ltd at Khetri, Rajasthan Hence, alternative uses of MT need to be thought while keeping in mind that the utilization Mine Tailings for Grout Free download as Powerpoint Presentation (ppt / pptx), PDF File (pdf), Text File (txt) or view presentation slides online presentationMine Tailings For Grout Construction Aggregate replacement of fine aggregate replacements varies as 0,25,50,75% of riversand The study explains that quarry dust has required properties of fine aggregate and 50% of quarry dust can be replaced in sand to produce optimum strength of concrete 25% replacement of quarrydust with fine aggregate gives same strength values as control mixStudy on Partial Replacement of Fine Aggregate by
