Shelf Life

Material needs thorough mixing before usage, and for bulk storage, site agitation or recycling pumps is a must.

Flocrete AF1 is suitable for several wet and dry shotcrete applications such as:

  • Inner lining.
  • Initial and permanent support of surfaces in underground spaces.
  • Slope and rock stabilization.
  • Repair and renovation work.


Flocrete AF1 is suitable to use with all types of Portland cement and cement replacement materials. Flocrete AF1 is compatible with other DCP admixtures when used in the same concrete mix.

If more than one type of admixture is to be used, they must be dispensed into the mix separately.
