Conbextra C is a dual shrinkage compensated, high flow cementitious grout for gap thicknesses from 10 mm up to 100 mm. Conbextra C can be used as a flowable or trowel applied grout.
Typical Applications
- Under baseplates and other applications where a precision high flow grout is required
Advantages
- Dual expansion system compensates for shrinkage in both the plastic and hardened states
- High ultimate strength and low permeability ensure the durability of the hardened grout
- Can be dry packed/rammed, trowelled, flowed and pumped
- Hydrogen free gas expansion
- Prepackaged material overcomes potential on-site mixing variations
- No metallic iron content to cause rusting
Key Properties

- Application method : Dry pack, trowel, pour or pump
- Chemical resistance : Not resistant to acids - use epoxy grouts
- Flexural Strength (modulus of rupture) @ 28 days : 96 Mpa
- Gap size : 10mm to 100 mm
- Indirect tensile strength @ 28 days : 48 MPa
- Service temperature : >200°C
- Set time : 75 hours
- Tack free time : 400-600 mm
