2018-3-9 To fulfill the objective six open pit iron ore mines were chosen where lateritic material is being removed by single shank ripper dozers. The field and laboratory investigations were performed and found that the ore rock is having uniaxial compressive strength between 5.09 to 22.65 MPa, point load strength between 0.54 to 3.22 MPa

2010-2-15 In their research, the iron recovery rate is 81.40% and the compressive strength of cured brick samples achieved the maximum peak of about 24.10 MPa at the content of hydrated lime of 13%. As a result, this kind of wastes can be comprehensive utilized by

2019-8-21 The load diameters, fracture diameters, and compressive strengths for the 2.01 lb/min and 3.67 lb/min rates are not significantly different at the 95% level, but these parameters are significantly different for the 3.67 lb/min and 4.20 lb/min rates. Some

The flexural strength and compressive strength of concrete, with iron ore decreased as a percentage increase in the replacement of iron ore. This can be concluded 40 % was not capable to be used but there may be some condition that need for this percentage. Nevertheless, the result had proven that concrete with iron ore is denser and heavy than
