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