The influence of the clinker sulfate on amounts of aluminate, alite and alite/belite ratio was investigated. The solubility rate of the clinker anhydrite was studied. The results showed that the clinker phases were affected by the amount of clinker SO 3 . The amounts of the aluminate, alite and alite/belite ratio were lower, in the high-SO 3 clinker, than that calculated. Based on these results, cement produced with clinker containing around 2% sulfate and low alkali were expected to have a higher sulfate resistance level than the classical one with similar chemical composition. It was also found that formation of the soluble anhydride was not feasible. The anhydrite that was present in the clinker containing over 2% SO 3 , seemed to be dissolved completely within 5 days.Read More
