Effect of desulfurization fly ash on cement properties and determination of sulfur content#br#
MA Chuanjie, et al
The experiment confirmed that the desulfurization fly ash would large affect the setting time of cement and the compatibility of cement and additive. The results showed that the maximum dosage of desulfurization fly ash should be less than 10% when SO3 content was more than 2%. The setting time of cement would significantly prolonged when using desulfurization fly ash, it should be appropriately added a certain proportion of limestone to shorten the setting time of cement. When using desulfurization fly ash, with the change of gypsum dosage, the setting time of cement changed little. The content of hemihydrate gypsum would produce superposition effect with the desulfurization fly ash, which would further prolong the setting time. The desulfurization fly ash contains a large amount of sulfite, When determining its SO3 content, the sulfite radical in fly ash volatilizes into SO2 due to the addition of hydrochloric acid, which results in a low measurement result. Therefore, for the determination of SO3 in the desulfurization fly ash, it was suggested to use fluorescence analysis or Eska method to convert sulfite into sulfate.
