This report proposes a modified spectrophotometric method with chrome azurol S for the determination of aluminium in portland cement. This method is simple and convienient compared to the conventional volumetric method (JIS R 5202), where the determination of iron and titanium in portland cement is needed before the detenmination of aluminium. In this method the values of aluminium are determined by a volumetric method with EDTA. In contrast to the JIS method, the modified spectrophotometric method with chrome azurol S does not require the predetermination of iron and titanium. The analytical results were in good agreement with those obtained by the JIS method.
