Description

Denka AFS (liquid) is an accelerator for shotcrete that has been developed for NATM/TBM tunnel excavation work.

Features

  • Quick setting time and high initial strength are realized through ettringite formation in the initial stage
  • Good bounding to the ground surface and low rebound
  • Low alkali content (<1%)

Application

  • Rock support in underground spaces (tunnels, headraces and mines)
  • Slope stabilization

Description

It is an adequate mixture of powered normal cement, Vinyl fiber and amorphous calcium aluminate. It shows superior Spraying property and strength developed characteristics by pairing premixed fiber mortar with a liquid accelerator.

Features

  • Improvement of tensile strength and toughness using vinyl fiber
  • Excellent bonding
  • Excellent early strength, long term strength
  • Low dust, low rebound

Application

  • Spraying after TDM drilling
  • Repair of adueduct tunnel
  • Urgent repair accompanying an adeduct tunne disaster

Packaging

25 kg bag, 500kg freight conveyor

Description
