No-fines concrete (NFC)
The mix consists of cement, water and course aggregate with fines (sand) omitted. After
prior moistening with water the aggregates are mixed with the cement and mix water.
This results in each particle of coarse aggregate being coated with a layer (up to about
1.3 mm) of cement paste which bonds it to adjacent particles in point-to-pint contact to
leave interstitial voids.
