Effects of iron ore tailings on the compressive strength ...

Nov 10, 2020  The addition of iron ore tailings enhances the compressive strength and impermeability of UHPC mortars due to the filling effect of IOT and the pozzolanic reaction of part of the finer IOT when the substitution rate is no more than 40%. The replacement ratio of 40% shows the best results, with low permeability and the maximum compressive strength.

Compression Testing of Green and Dry Iron Ore Pellets

Aug 21, 2019  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 of the increase in fracture load is caused by the immediate failure of the weaker pellets.
