SikaGrout®-212 HP
SikaGrout®-212 HP is a high-performance, non-shrink, fluid, cementitious grout formulated with silica fume and a unique two-stage mechanism, compensating for shrinkage in both the plastic and the hardened states. It is non-metallic, contains no chlorides and it may be placed at various consistencies ranging from dry to fluid by simply adjusting the quantity of mix water.
- Pre-blended for easy application and maximum field control. Just add water, mix and place
- Versatile, can be applied in any consistency from dry, plastic or fluid by varying water content
- Reducing water content accelerates strength development and ultimate compressive strength values
- Non-corrosive, does not contain chlorides
- Formulated with inert, non-reactive aggregates to eliminate potential Alkali-Aggregate Reactivity (AAR)
- Excellent pumpability, does not segregate, even in fluid state. No build-up on equipment hopper
- Low heat development
- Superior freeze/thaw resistance
Usage
- On grade, above and below grade, interior and exterior applications, especially where the grout is required to resist increased exposure to freeze/thaw, the presence of salts or other such aggressors
- Structural grouting of machine base plates, paper presses, column base plates, anchor bolts, bearing plates, and bridge seats
- On grouting projects where the consistency of the grout needs to be adjustable to allow for accelerated strength development requirements, for example wind turbine grouting.

*Fluid consistency compressive strengths are given as minimum guidelines. Pourable and dry pack consistencies will easily exceed these values. All moulds, mixing tools and powder components were pre-conditioned to the test temperatures. Prepared test specimens were cast and then cured at the indicated test temperatures until the time of testing. Lid should be clamped on mold at all time. Liquid/solids ratio (water + Sikacem® Accelerator/SikaGrout®-212 HP) = 0.176; [4.4 L (1.16 US gal.) of liquid per 25 kg (55 lb) bag of SikaGrout®-212 HP].

MIXING
Mix using a heavy duty low-speed drill/mixer (300–450 rpm) and mixing paddle (Jiffy or Exomixer®/spiral type) or using a grout mixer. In a clean pail or mixer, add only the necessary amount of water for the required consistency without exceeding 4.4 L (9.3 pt) of water per bag. Add the bag content and mix for three (3) minutes until a uniform consistency is achieved.
Notes: For application greater than 150 mm (6 in) in thickness, add up to 12 kg (26.5 lb) of 10 mm (3/8 in) coarse aggregate (as per ASTM C33, Table 2, size number 8). The aggregate must be non-reactive, clean, well graded, saturated surface dry (SSD), have low absorption, high density and comply with ASTM C33
APPLICATION
Important: Make sure not to use the grout in unconfined areas.
The prepared SikaGrout®-212 HP may be pumped or transported to the forms in buckets or wheelbarrows and deposited without delay. External vibration and agitation of the grout in the forms is permitted. The prepared grout shall be agitated until used. Grout having been prepared but not placed within 45 minutes after mixing shall be discarded. After initial set, exposed grout may be trimmed or shaped to desired finish
Forming: Forms should be left as long as possible but not removed before 24 hours at 23 °C (73 °F)
Dry pack application: Refer to the Sika Cementitious Grouting Method Statement.
CURING TREATMENT
To achieve performance consistent with Technical Data, curing is required and must be provided as per ACI 308 recommendations for cement concrete. Execute curing by recognized methods such as wet burlap covered with white polyethylene film, misting with water, or approved water-based curing compound, such as Sika® Florseal WB-18 & -25. Alternatively, the use of Sika® UltraCure DOTTM or NCFTM wet curing blankets is strongly recommended. Curing must commence immediately after placing and finishing. Protect freshly applied product from direct sunlight, strong winds, rain and freezing.
CLEAN UP
Clean all tools and equipment after use with water. Once hardened, the product can only be removed mechanically. Wash soiled hands and skin thoroughly in hot soapy water or use Sika® Cleaning Wipes-120.
