No-fines concrete is obtained by eliminating the fine material sand, from the normal concrete mix. The single-sized coarse aggregates are surrounded and held together by a thin layer of cement paste giving strength of concrete.

The advantages of this type of concrete are:

●     Lower density.

●     Lower cost due to lower cement content.

●     Lower thermal conductivity relatively low drying shrinkage.

●     No segregation and capillary movement of water.

●     Better insulating characteristics than conventional concrete because of the presence of large voids.

No-fines concrete is not suitable for use in reinforced concrete.
