SikaGrout® Cable PT SA

HIGH PERFORMANCE, ZERO BLEED, SAND FREE, CEMENTITIOUS GROUT FOR POST-TENSIONED STRUCTURES

SikaGrout® Cable PT SA is a non-shrink, cementitious cable grout with a unique 2-stage shrinkage compensating mechanism. It is non-metallic & contains no
chlorides. With a special blend of shrinkage-reducing and plasticizing / water reducing agents. SikaGrout® Cable PT SA compensates for shrinkage in both the plastic & hardened states.
Suitable for use in hot and tropical climatic conditions.

  • Allows shrinkage & repairing of voids within ducts of post tensioned structures
  • Does not contain aluminium powder or any components which generate hydrogen gas, carbon dioxide or oxygen
  • Easy to use
  • Non-metallic will not stain or rust
  • Zero bleed even at high flow
  • Low heat build-up
  • Excellent for pumping: Does not segregate even at high flow / pressure

Application steps

MIXING

For cable duct grouting use a colloidal mixer / high shear mixer at approximately 2500 rpm. Mix for approximately 3 minutes, after the addition of the last bag or until a homogenous mix is achieved. Continue to agitate material in the holding hopper to achieve optimum flow. Method of mixing may significantly affect the material properties, particularly flow. At higher temperatures and / or with higher water volumes, the grout will behave less thixotropic. Therefore, it may be more appropriate to measure the flow using the standard flow cone test (ASTM C-939). The expected flux time is between 11 - 30 seconds under normal conditions. At higher temperature use chilled water & store the bags in a cool place to keep the mixed grout temperature below 25 °C wherever possible. For other grouting applications, double mixer with spindle basket paddles, can be also used for mixing; the mixing time should be extended to 7 minutes to get the required flow.

APPLICATION

Make sure all forming, mixing, placing, and clean-up materials are on hand. The method of pumping the grout must ensure complete filling of the ducts and complete surrounding of the strands or bar. A mockup should be completed on site and inspected by the engineer to ensure that the placement meets specified requirements.

For additional corrosion protection, add 100 grams of Sika® Ferrogard®-901 per bag of grout by replacing same amount of mixing water if needed.


When grouting ducts or other critical elements, it is highly recommended that experienced, trained technicians complete the work.

CLEANING OF EQUIPMENT

Clean all tools and application equipment with water immediately after use.
Hardened / cured material can only be mechanically removed.
