Sika® Plastiment® TM-25

Water-reducing and set retarding concrete admixtures

In Fresh state

  • Initial setting is delayed allowing time for proper placement and compacting new layer over the retarded RCC, without cold joint.
  • Decrease the mortar of concrete bonding volume
  • Increase the time available to re compacting the concrete without damaging the material. After the initial set heavy transits can dam age the newly hydrated RCC.
  • Increase of the cement efficiency
  • Diminish the rate of initial heat generation.

In hardened state

  • Increase the mechanical strengths in any weather conditions.
  • Diminish the heat generation and the cracking risk
  • Increase the density of the RCC
