Should the presence of ggbs be noted during analysis for cement content the sulfide content can be determined and the correct proportions calculated. The presence of HAC can be confirmed by analysis to BS 1881 with the additional determination of aluminium allowing the calculation of aluminium:silica and aluminium:calcium oxide ratios for comparison with accepted values for OPC and HAC concrete.
