Conbextra HES

Conbextra HES is a shrinkage compensated cementitious grout used for free flow grouting in a wide range of applications where rapid strength gain is a pre-requisite. Conbextra HES has a compressive strength of 25 MPa @ 2 hours when mixed at flowable consistency.

Typical Applications

  • Grouting machine bases etc where very quick return to service is required

Advantages

  • Rapid strength gain facilitates rapid installation and operation of plant within a matter of hours
  • High strength gain is achievable even at low temperatures
  • Excellent initial flow and flow retention
  • Unique system compensates for shrinkage in hardened state
  • High ultimate strength and low permeability ensure durability of the hardened grout
  • Chloride free
  • Suitable for pumping or pouring over a large range of application consistencies and temperatures
  • 28 day strength @ 20°C dependent on consistency (cube samples) : 50-58MPa
  • Application method : Pump or pour
  • Chemical resistance : Not resistant to acids - use epoxy grouts
  • Flexural Strength (modulus of rupture) @ 28 days : 65MPa
  • Gap size : 15mm to 150mm
  • Indirect tensile strength @ 28 days : 30MPa
  • Service temperature : >200°C
  • Set time : 50 mins
  • Tack free time : 350mm
