Jan 01, 2018· The unconfined compressive strength (UCS) of cast 6×12-inch QA/QC cylinders is typically used as an index test to track the performance of a backfill plant. However, these strengths need to be adjusted for oversize aggregate removal and sample size effects if used to estimate the emplaced UCS.
Due to economical and environmental issues, utilization of mineral wastes, e.g. iron ore mine tailing (IOMT), as road materials can be recommended as a sustainable alternative.

For control sample UCS strength is about 17.22 kPa.
Iron ore tailings (IOTs) are the wastes obtained from the beneficiation of mined iron ore. In Nigeria, about 3072 tons/day are mined at Itakpe mines [25]. The total world production of iron ore in 2014 was 3.22 billion tons and for each ton of beneficiated iron ore, it is estimated that about 40% of tailings are produced [26]. Tailings have been
Uniaxial compressive strength (UCS) is a key physical test relevant to iron ore crusher design and rock geomechanics for mining. Tests are typically performed on intact lengths of NQ, HQ, or PQ diamond drill core and record the maximum axial load sustained at the point of failure.
