Blended Cement - an overview | ScienceDirect .

Modelling and testing of the leaching of concretes formed with blended cements have shown that leaching levels are the same as for Portland cement. Blended cements based on blast furnace slag show low Cr(VI) leachability resulting from the inherent reducing properties of blast furnace slag which will transform any Cr(VI) produced in the cement kiln to Cr(III), ( ECOserve Network, 2004a ).
