  1. W water, C cement, FA fly ash, BS blast furnace slag, S sand (fine aggregate), G gravel (coarse aggregate).
  2. aThe name of mixtures were determined based on the types of reinforced fiber: SF (steel fiber), PF (polyaramid fiber).
  3. bWater-to-binder ratio.
  4. cSand-to-aggregate ratio.
  5. dSuperplasticizer (polycarboxylate-based).
