Oct 04 2015 The present study looks for the feasibility of preparing UHPC with iron ore tailings IOT for short as fine aggregate. To enhance outstanding high performances some influences on UHPC mortars were investigated such as different kinds of sands different mix ratio of sands and different largest particle size of fine aggregate. The results show that IOT have negligible

Jul 05 2010 Iron oxide particles as produced for the construction industry are 10 times finer than cement particles. When added into a concrete mix the iron oxide particles actually surround and coat the cement particles. This is why integral color is dosed or metered based on the cement content not on the amount of sand stone or water.
