What's the use of iron ore slag?
Slag Portland cement, referred to as slag cement. It consists of Portland cement clinker, granulated blast furnace slag 20%-70% and a proper amount of gypsum.
The largest is the raw material used as slag Portland cement.
Properties of Portland blast furnace cement:1. High strength and high performance concrete can be prepared.2, fine slag powder concrete water retention, good plasticity, less bleeding, with a good job. 3, reducing hydration heat is helpful to prevent cracks caused by temperature rise of mass concrete.Ettringite crystallization of calcium 4, produce more compensation, because of too much powder concrete caused by dry shrinkage.5, hardened concrete has good resistance to sulfate attack, reducing and inhibiting the proliferation of chloride ions, as well as resistance to seawater erosion, anti carbonation, alkali resistance - aggregate [aggregate] reaction.
