Conbextra UW

Conbextra UW a flowable under water cementitious grout which exhibits exceptional resistance to washing-out of the cement phase when placed in stationary or moving water.

Typical Applications

  • Grouting or concrete reinstatement in submerged conditions such as wharf piles

Advantages

  • No risk of significant wash-out of cement phase when placed underwater
  • Displaces water effectively
  • Gaseous expansion system compensates for shrinkage and settlement in the plastic state
  • High early and ultimate strength
  • Chloride free
  • Pre-packaged needing only on-site addition of water
  • 28 day strength @ 20°C dependent on consistency (cube samples) : 53MPa
  • Application method : Pump or pour
  • Flexural Strength (modulus of rupture) @ 28 days : 88MPa
  • Flow characteristics @ 20°C (depending on gap size) (flow trough) : 400mm
  • Gap size : 10mm to 80mm above water 10mm to 150mm below water
  • Indirect tensile strength @ 28 days : 41MPa
  • Movement accommodation factor : >200°C
  • Set time : 75 hours
