- •
Silica flour–Silica fume combinations improved the early age compressive strength.
- •
Increase in fineness of silica flour improved the early-age strength of HPCM.
- •
Combinations of silica fume and silica flour reduced permeability of HPCM.
- •
Higher fineness and dosage of silica flour increased drying shrinkage of HPCM.
- •
RCP and permeable voids of HPCMs showed a good correlation.
