Sika® Injectoset TH

Set accelerating agent for cementitious grout

Sika® Injectoset TH is a set accelerating agent based on metallic silicate to produce cementitious grout with adjustable setting time.

  • Avoid wash out of the freshly pumped grout when grouting under water.
  • Allow early setting also under wet condition.
  • Depend on the its dosage and the grouting set up, the setting time of the grout can be adjusted
  • Non Flammable
  • Can be applied to damp (not wet) substrates.

Usage

Sika® Injectoset TH is used with normal cementitious grout where adjustable setting of the grout is required. It can be added into the grout mix when grouting work is required to fill gravelly and sandy soils, to stabilize loose and fracturated rock fissures, to seal lowmedium water infiltrations, to perform “jetting” in wet condition, to fix anchors.  

Advantages

  • Avoid wash out of the freshly pumped grout when grouting under water.
  • Allow early setting also under wet condition.
  • Depend on the its dosage and the grouting set up, the setting time of the grout can be adjusted
  • Non Flammable
  • Can be applied to damp (not wet) substrates.

Consumption

Consumption

Depending on the final result expected and the local conditions (wet condition, injection distances, the type of application).
Very Fast Setting of the Grout : 1.5-3% by weight of cement.
Early setting of the Grout : 0.5-1.5% by weight of cement.
Sika® Injectoset TH efficiency depends on the W/C of the cementitious grout mix, on the type, age and quality of cement. The consistency, the pot life required of the grout mix and consequently the addition of Sika® Injectoset TH depend as well on the geology (USCS classification, permeability k m/s, D15 ). Preliminary trials are recommended.
Application steps

MIXING

Use only fresh cement when preparing the grouting mix. Grouting mix needs to be flowable or pourable consistency for successful pumping. In order to reduce the water content of the mix by still maintaining suitable flowable properties, superplasticiser type ASTM F can be added like Sikament® F6 at the dosage of 0.8– 2.0% by weight of cement.Before attempting to mix and to pump the grout mix, it is recommended to rinse the mixer and charge the pump hopper with sufficient water to flush the pump and all grout lines. Once this has been achieved, remove the grout hose from the pump and drain out all water. Prepare and pump cementitious slurry (0.7 < W/C < 0.8) in order to remove residual water and to lubricate the grouting system.
Very Fast setting grout: use a bi components pump. Sika® Injectoset TH being added at the end of the packers. Proper grouting application will depend on the grouting equipment available, therefore please contact Technical Department.
Early setting grout: Prepare the approved mix accordingly and add into the mix Sika® Injectoset TH according to specified dosage. Maintain further mixing for 1 minute before stating the grouting. The grout can be pumped directly after the lubricating mix slurry. Use the grout mix without delay otherwise the grout mix would show its consistency changing. This may occur grout pressure increase or blockage.
