Uses

Heavy duty precision grouting of gaps from 10mm to 125mm, where high flow and high ultimate strength is required. Applications include grouting of:

  • Baseplates and soleplates of large machines subject to moderate dynamic loads
  • Crane rail soleplates
  • Precast wall panels, beams, columns and structural building members

Advantages

  • Non-metallic dual expansion system compensates for shrinkage in both the plastic and hardened states
  • Excellent initial flow and flow retention suitable for large and small grout pours
  • 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 over a large range of application consistencies and temperatures

Description

Conbextra HS, shrinkage compensated ultra high-strength cementitious precision grout, is supplied as a ready to use dry powder. The addition of a controlled amount of clean water produces a free-flowing precision grout for gap thicknesses up to 125 mm. In addition the low water requirement ensures high early strength and long term durability. Conbextra HS is a blend of Portland cements, graded fillers and chemical additives which impart controlled expansion in both the plastic and hardened states. The filler grading minimises segregation and bleeding over a wide range of application consistencies.

Maximum aggregate size for pumping is 1.0 mm.
