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.
 
  • Possible contact with drinking water.
  • It is resistant to sea water and sulphate water.
  • It has good resistance to internal frost and chipping.
  • 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 perfectly to shocks and vibrations
  • It is not altered by important vibrations, humidity or temperature; it resists to water and oil.
  • It can be mixed with fillers to make thick or thin wedging and sealing lume.

Mixing ratio

Amount of mixing water is 3.25 to 3.5 liters per 25 kg bag. In on-site practice, this quantity can be adjusted between 3.5 and 3.75 liters depending on the climatic conditions and the desired consistency. Note: Characteristics are obtained for a quantity of water between 13% and 14%.

Consumption

Consumption

A 25 kg bag of SikaGrout®-217 mixed with 3.25 to 3.5 liters of water yields about 14 litres of fresh mortar. To fill out a lume of one litre of cushioning or sealing, the consumption is therefore approximately 2 kg of SikaGrout®-217.

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

MIXING

Put the necessary water into the mix container and gradually add SikaGrout®-217 while stirring in order to avoid lump formation. Continue stirring until a homogenous mix is obtained (2 to 3 minutes). The mixing can be done in an open container using an electric or pneumatic stirrer working at low speed (around 300 rpm)

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 liters of mixing water.

Waiting time before commissioning: The waiting time before commissioning depends on the required mechanical strength. It is generally ~ 24 hours at a temperature of 20 °C

CLEANING OF EQUIPMENT

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