Groutex Plasticiser – Expanding / Plasticising Grout Admixture
Groutex plasticiser consists of a refined lignosulphonate plasticiser plus a finely divided coated aluminium powder. The plasticiser enables high workability mixes to be produced at low water contents and the aluminium powder dissolves in the cement
paste to produce a positively expanding material. After setting there is no metallic residue or staining from the low pressure expansion system. Groutex is chloride free and can be safely used in contact with steel reinforcement, post-tensioned cables
and pre-stressed wires. The micro-cellular structure of hardened grout gives low permeability and good freeze thaw stability. Mixes containing Groutex give good flow and easy placement helping to obtain complete filling of the work piece. The non-shrink characteristics prevent plastic settlement producing permanent contact between grouted surfaces.
Groutex is used as an add mixture for cementitious grouts and mortars to improve flowability and non-shrink characteristics. Applications include base-plate grouting, under pinning, structural packing and shrinkage compensated repair mortars.
- Cost effective.
- Enhanced Workability.
- 4% expansion properties.
Free Expansion: Free expansion is in the range 1% to 4% starting 20 minutes after mixing and is complete 2 hours after mixing.
Setting Times: The inclusion of Groutex does not significantly affect setting times of Portland cement mixes.
