abstract = {This study compared waterglass- and NaOH-activated slag concrete (AASC) rheology to the behaviour in OPCC concrete. The effect of mixing time on fresh concrete rheology was also assessed. A rotational rheometer was used to apply shear stress to the materials to determine static and dynamic yield stress at 15, 30, 45 and 60 min of age. Concrete strength and porosimetry were determined to relate rheology to hardened concrete behaviour. The results indicate that slump and rheological behaviour of OPCC and AASC are different, scpecially when the alkaline activator is waterglas (AAS WG). The mixing protocol appeared to affect concrete rheology (fresh behaviour) more than its strength (hardened behaviour). In AASC WG, both rheological and mechanical behaviour improved at longer mixing times. © 2017 American Concrete Institute. All rights reserved.},
