SikaGrout®-217

High Performance, Shrinkage Compensated Grout

SikaGrout®-217 is a ready to use cementitious mortar. After mixing with water, it yields a grey fluid mortar

  • SikaGrout® 217 does not contain metallic aggregates nor chloride. It does not corrode in presence of humidity, but rather protects steel rebars from corrosion thanks to its alkaline pH.
  • It has high flexural and compressive strengths, even early strength, which allows for quick machines commissioning
  • SikaGrout® 217 is shrinkage-compensated. A controlled expansion system is triggered to compensate the effect of first and second shrinkage
  • It has excellent adhesion on concrete, mortar and steel. It ensures a monolithic link and resists per-fectly to shocks and vibrations
  • It is not altered by important vibrations, humidity or temperature; it resists to water and oil.

Usage

  • Grouting of turbines,
  • Grouting of beams or bedding for bridges’ bearing devices
  • Assembly of prefabricated elements in metal, reinforced concrete or prestressed concrete
  • Precision grouting of industrial equipment subject to chocks and vibrations
  • Anchoring of rails
  • Anchoring of rebars in horizontal elements

Application

Application Information

Layer thickness

Minimum 10 mm/ maximum 150 mm

Thicker applications can be achieved. Contact Sika® Technical Services Department for further information.

Ambient air temperature

The ambient temperature shall be between + 5 °C and + 35 °C.

Mixing ratio

3.25 L - 3.50 L of water per 25 Kg bag 

Pot Life

20 Minutes 

As the temperature will affect the pot life, application temperature:

  • Above 23 °C will reduce the pot life and flow
  • Below 23 °C will extend the pot life and flow
Consumption

Consumption

A 25 kg bag of SikaGrout®-217 mixed with 3.25 - 3.50 liters of water yields about 14 liter of fresh mortar. 

Note: Characteristics are obtained for a nominal amount of water is between 13% and 14% of the dry mix.

The consumption data is theoretical and excludes allowances for loss wastage, surface profile and porosity.
Application steps

MIXING

  • Place the water into a forced action grout mixer or in a clean drum.
  • Slowly add complete bag of SikaGrout®-217 into the water and continuously mix for 2 minutes in mixer to achieve a uniform and lump free consistency.
  • Alternatively use a slow speed drill (200-500 rpm) and helical mixer.
  • Dependent on the desired consistency and flow properties, the mixing ratio can be adjusted. Measure the appropriate amount of water to achieve the desired grout consistency given in the table below.
  • Heat water if necessary to achieve a temperature between 15-23°C (for extremely cold tempratures conditions)

APPLICATION

Application is done by pouring, pumping or injection. Adding Aggregates in cases where there are important thicknesses to fill, it is possible to form a grouting micro-concrete having good fluidity and good strength at 28 days. This is done by adding aggregates with grains sizes 3/8 mm at a ratio of 12.5 kg per 25 kg bags of SikaGrout®-217. Use 3.25 - 3.5 liter of mixing water.

CURING TREATMENT

After SikaGrout® 217’s placement, it shall be protected against wind and sun exposure during its hardening.

CLEANING OF EQUIPMENT

Clean all equipment and tools with water immediately after use. Dry hardened material can only be removed mechanically.
