Conbextra HF

Conbextra HF is a dual shrinkage compensated high flow cementitious precision grout for gap thicknesses up to 125 mm. Conbextra HF has excellent flow retention properties.

Typical Applications

  • Precison grouting where high flow and long flow property retention is required

Advantages

  • Excellent initial flow and flow retention
  • Rapid strength gain facilitates efficient installation and operation of plant
  • High ultimate strength and low permeability ensure durability of the hardened grout
  • Hydrogen-free gaseous expansion
  • Chloride free
  • Suitable for pumping or pouring
  • 28 day strength @ 20°C dependent on consistency (cube samples) : 60-77MPa
  • Application method : Pump or pour
  • Chemical resistance : Not resistant to acids - use epoxy grouts
  • Flexural Strength (modulus of rupture) @ 28 days : 100MPa
  • Gap size : 10mm to 125mm
  • Indirect tensile strength @ 28 days : 47MPa
  • Service temperature : >200°C
  • Set time : 75 hours
  • Tack free time : Flow cone 19-25 seconds
