No-fines concrete

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.
