Conbextra GP

Conbextra GP is a general purpose shrinkage compensated (Class A) cementitious, flowable or trowellable grout for gap thicknesses from 10 mm up to 100 mm. Conbextra GP has a 28 day compressive strength of 65 MPa when mixed at trowellable consistency.

Typical Applications

  • General site grouting where higher compressive strength is required

Advantages

  • High ultimate strength and low permeability ensure the durability of the hardened grout
  • Gaseous expansion system compensates for shrinkage and settlement in the plastic state
  • Can be dry packed, rammed, trowelled, poured and pumped
  • Pre-packaged material overcomes potential on-site mixing variations
  • Develops high early strength without the use of chlorides
  • No metallic iron content to cause staining
  • Complies to AS/NZS 4020:2005 Products in Contact with Potable Water
  • 28 day strength @ 20°C dependent on consistency (cube samples) : 65-75MPa
  • Application method : Dry pack, trowel, pour or pump
  • Chemical resistance : Not resistant to acids - use epoxy grouts
  • Flexural Strength (modulus of rupture) @ 28 days : 136MPa
  • Gap size : 10mm to 100mm
  • Indirect tensile strength @ 28 days : 61MPa
  • Service temperature : >200°C
  • Set time : 75 hours
  • Tack free time : 400 - 600mm
