The present paper points out the importance of three main subjects concerning the presence of sulphur compounds in concrete: i) the maximum sulphate content of concrete aggregates specified in the Spanish concrete standard; ii) the standardized analytical method to determine sulphur compounds in aggregates for concrete; and iii) the troubles caused by sulphides and sulphates in concrete. The author suggests the possibility to revise the present limit for the content of sulphur in any state of valence in aggregates and other concrete materials, as well as the convenience to distinguish sulphur as sulphide from sulphur as sulphate in the total sulphur content of the aggregates, taking into account the different detrimental effects of both forms of sulphur in concrete.
