Conbextra HS

High flow, high ultimate strength, dual shrinkage compensated, precision cementitious grout.

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 of 10mm to 125mm. 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 1.0mm.

Uses

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

• Baseplates and soleplates of large machines are subject to
  moderate dynamic loads
• Crane rail soleplates, 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
