Study on Speciation of Cr in Cement

Abstract:

A modified Tessier sequential extraction procedure was employed to investigate the speciation of Cr in cement products. The amount of Cr in extracting solution was determined by atomic absorption spectrophotometer and extraction residue was analyzed based on the results of XRD, SEM and EDS. The distribution of Cr in cement was discussed also. Cr existing as species exchangeable or bound to carbonates increases with curing age gradually.
