King® Nordic Cable
HIGH PERFORMANCE NEAT ANCHORING GROUT FOR COLD WEATHER APPLICATIONS
King® Nordic Cable is a high performance, easily pumpable, pre-mixed and pre-packaged unsanded cementitious anchoring grout specially designed for cold weather applications.
- Excellent compressive strength development in cold weather and permafrost
- Excellent pumpability
- Excellent cohesion and plastic stability
- Thixotropic properties reduce material loss in fractured ground
- Non-corrosive, non-chloride, non-metallic
Usage
King® Nordic Cable is ideal for anchoring applications in cold weather and in different types of substrates subject to frost:- Most grouted anchor requirements including cable bolting, earth tie-backs for excavation or soil stabilization, grouting anchors in tunnel support systems, re-bar grouting, and grouting soil or rock tendons for anchoring piles or foundation structures
- Grouting of most types of anchors such as tendons, cables, dowels or bolts used in substrates subject to frost (freezing index below 3500 degree days)
- Practical for curing temperatures between -5 °C (23 °F) and +5 °C (40 °F)
Advantages
- Excellent compressive strength development in cold weather and permafrost
- Excellent pumpability
- Excellent cohesion and plastic stability
- Thixotropic properties reduce material loss in fractured ground
- Non-corrosive, non-chloride, non-metallic
Packaging
- 30 kg (66 lb) bags
*Custom packaging is available to suit specific project requirements

MIXING
In order to achieve the mechanical and plastic properties listed in the Technical Data section, the plastic temperature of King® Nordic Cable after mixing must be between +15 °C and +25 °C (59 °F and 77 °F). The bags of King® Nordic Cable and batching water must be maintained in a dry, closed/contained environment protected from the elements. Material must be kept at temperatures above +15 °C (59 °F) and the water should be conditioned to temperatures ranging from +15 °C (59 °F) to +25 °C (77 °F), prior to mixing. It is recommended to store and operate the grout mixer in a dry and closed environment (ex. container protected from the elements and maintained at temperature ranging from +15 °C (59 °F) to +25 °C (77 °F).
Use potable water only. Introduce the required volume of water into the paddle mixer and gradually add product while operating at medium speed. Increase the mixer speed and continue mixing for two (2) minutes. Then, decrease the mixer speed to low and continue mixing while placing the grout. The time between the mixing and pumping of a batch should not exceed 20 minutes.
Note: If a thicker consistency is desired, contact your Sika Technical Representative for additional information.
When mixing a single 30 kg (66 lb) bag of King® Nordic Cable, it is possible to use a hand-held electrical drill mixer fitted with an appropriate mixing-paddle designed to mix unsanded grouts.
APPLICATION
OPTIMUM PERFORMANCE
- Temperature of freshly mixed grout must be between +15 °C (59 °F) and +25 °C (77 °F)
- It is recommended to use a bore hole size that is at least 50 mm (2 in) greater in diameter than the reinforcing steel used, in order to ensure that enough grout is present in the anchor for proper performance
CLEAN UP
Clean all tools and equipment after use with water. Once hardened, the product can only be removed mechanically.
