Conbextra CB

Conbextra CB is a highly flowable high strength grout which can be used for various void fill applications including, backfilling behind concrete tunnel segments and bottom up cable bolt grouting applications.

Typical Applications

  • Grouting cable bolts
  • Back filling tunnel segments

Advantages

  • High strength development allows early tensioning of cables
  • Gaseous expansion system compensates for shrinkage in the plastic state
  • Develops early high strength without the use of chlorides
  • Excellent pumpability over both flowable and thixotropic consistencies
  • 28 day strength @ 20°C dependent on consistency (cube samples) : 75-100 Mpa
  • Application method : Pump or pour
  • Flow characteristics @ 20°C (depending on gap size) (flow trough) : Free flowing
  • Service temperature : >200°C
  • Set time : 75 hours
