SikaRapid®-786 PK

Accelerator for Higher Early Strength

SikaRapid®-786 PK is an accelerator for higher early strength ready to use, liquid admixture to produce quality concrete while accelerating setting time and strength development.

Improved workability
  • Superior finishing characteristics for flatwork and cast surfaces
  • Earlier finishing of slabs – reduced labor costs
  • Reduced protection time in cold weather
  • Earlier stripping and reuse of forms
  • Earlier structural use of concrete
  • Precast concrete: SikaRapid®-786 PK delivers excellent results for precast concrete when high early strengths are required. Curing times are significantly reduced while concrete quality is improved.

Application steps

MIXING

Add correct amount of SikaRapid®-786 PK at the concrete plant or into ready mix truck at the job site. The admixture may be added manually or by automated dispenser directly into the sand or into the water line at the batch plant. When used in combination with other admixtures care must be taken to dispense each admixture separately into the mix. Do not mix with dry cement.
Use With Other Admixtures:
SikaRapid®-786 PK performs well in combination with other admixtures such as non retarding water reducers, high range water reducers and air entraining agents. Do not mix SikaRapid®-786 PK with expansion agents or shrinkage compensating agents.
