Reduced rate of structural build-up was observed with the use of fly ash and metakaolin.
Total structural build-up was 1740 Pa for reference mix, while blended systems ranged from 420 to 840 Pa after 90 min at 20 °C.
Isothermal calorimetry tests were conducted to assess hydration and rheological properties influenced by SCMs.
Findings highlight the importance of material selection in optimizing self-compacting concretes' early stability.
