- •
Agricultural residue ash (ARA) samples were prepared with high surface areas.
- •
ARAs showed similar pozzolanicity to silica fume.
- •
Internal surface area of ARAs did not affect cement early hydration.
- •
ARAs reduced influence of retarders in cement paste due to their high surface areas.
- •
ARAs adsorbed a high amount of air entraining agent in cementitious systems.
