Admixtures for Shotcrete

Sigunit® LS

Liquid Shotcrete Accelerator.

USE
Sigunit® LS is used for accelerating the set of dry or wet sprayed concrete mixes. The main fields of applications are:
Temporary support in underground constructions excavated by the traditional method (NATM)
Slope stabilization
Dewatering work in dry process configuration

CHARACTERISTICS AND ADVANTAGES

  • Reduction of the spraying time as application of thick layers is possible
  • Create a rapid setting of the shotcrete
  • Free from Chlorides (can be used with shotcrete containing steel fibers– eg SikaFiber® CHO)
  • Large reduction of rebound as long as the spraying is performed according to the states of the art
  • Improves bonding of sprayed concrete to rock, concrete

PACKAGING
250 kg

  • Securing of rock in tunnel and mine construction (preliminary support)
  • Rock and slope stabilization
  • Dewatering work by dry process
  • High quality shotcrete for permanent support by shotcrete

CHARACTERISTICS AND ADVANTAGES

  • Alkali free and non toxic
