Abstract The chromate content of 10 different Asian cements is studied. The hexavalent chromate and total chromium concentrations in these cements were analyzed using colorimetric spectrophometry and flame atomic absorption spectrophotometry, respectively. The pH of an aliquot of 20% w/v of cement in water ranged from 11.8 to 12.1. Total chromium content of the 10 brands of cement ranged from 15.9 ug/g to 30.0 ug/g; the hexavalent chromate content ranged from 3.6 ug/g to 25.1 ug/g. These findings were comparable to those reported in Europe and Scandinavia. There was no direct correlation between total chromium and hexavalent chromate content in cement.
