Increased dosage rates improved performance in general for all SCMs except silica fume and Class C fly ash. An analysis on correlating fly ash performance to chemical composition indicated that oxide content alone could not be used as the sole indicator of fly ash sulfate attack mitigation potential. In magnesium sulfate at higher replacement rates, the performance was mixed for metakaolin and silica fume as indicated by increased expansion relative to a control. Overall, fly ash, slag, silica fume, and metakaolin can be effective in mitigating sulfate attack, but their performance is dependent on replacement rate, sulfate cation exposure, and their chemical and physical properties.]]> Thu 23 Nov 2023 12:20:05 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:49782 Fri 02 Jun 2023 17:28:43 AEST ]]>
