Overview

Randomized trial optimizes alkali-activated materials hydration in cementitious systems, indicating improved performance.

Key Points

  • This research aims to enhance the mix design of fly ash and GGBS systems while elucidating hydration mechanisms.
  • Optimized mix ratios using Response Surface Methodology with a Box-Behnken design.
  • Evaluated effects of precursor content, activator modulus, and alkali content on fresh workability and mechanical properties.
  • Utilized low-field NMR, isothermal calorimetry, and microstructural characterizations.
  • Achieved peak compressive strength of 85.5 MPa with 70% GGBS content and activator modulus of 1.2.
  • Higher alkalinity and GGBS content significantly accelerated reactions and reduced setting times.
  • Proposed a three-stage hydration mechanism highlighting a dual activation effect between FA and GGBS.
