  • The Benefits of Tried and True Iron Oxide ..

    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.
