SikaGrout®-212
SikaGrout®-212 is a non-shrink, cementitious grout with a unique two-stage shrinkage compensating mechanism, compensating for shrinkage in both the plastic and the hardened states. It is non-metallic, chloride-free and may be placed at various consistencies ranging from dry pack to fluid by simply adjusting the quantity of mixing water. A sulphate resistant grade, SikaGrout®-212 SR, and a silica fume modified grade, SikaGrout®-212 HP, are also available (see separate Product Data Sheets).
- Pre-blended for easy application and maximum field control. Just add water, mix and place
- Versatile, can be applied in any consistency from dry pack to fluid by varying water content
- Reducing water content accelerates strength development and ultimate compressive strength
- 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 at high flow; no build-up on equipment hopper
- Low heat development
- Superior freeze/thaw resistance
Usage
- On grade, above and below grade, interior and exterior applications
- Structural grouting of column base plates, machine base plates, anchor bolts, bearing plates, bridge seats, precast wall panels
- On grouting projects where ability to adjust consistency and achieve accelerated strength development is required

*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.

SURFACE PREPARATION
All grease, oil laitance, ice or snow and any foreign deposits shall be removed from all surfaces with which the grout will come in contact. The concrete foundation shall be roughened to the extent that it does not present a smooth surface, which would impede the bond of the grout to the foundation. All dust and loose particles shall be removed by sandblasting, high pressure waterblasting or other suitable means.
Concrete foundations less than 28 days old shall be kept wet for at least 12 hours, and older foundations for a minimum of 24 hours before placing grout (SSD condition). All free-standing water shall be removed from concrete surfaces prior to grouting. All items to be grouted into place shall be properly positioned and anchored prior to grouting except for anchor bolts and dowels, which may be placed into the fresh grout if job conditions permit and at the discretion of the engineer in charge. For grouting of base plates the formwork used to contain the grout shall be appropriately constructed and caulked to prevent leakage of grout. Provisions shall be made at the high points for air to be vented as it is displaced by grout.
MIXING
Mix using a heavy duty low-speed drill (300–450 rpm) and mixing paddle (Jiffy or Exomixer®) or in a grout mixer. The size of the mixer should be appropriate to the volume of grout required. Use a minimum amount of water consistent with placeability requirements. After all dry product has been added to the water, continue mixing for three (3) minutes. 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. The aggregate must be non-reactive (reference ASTM C1260, C227, and C289), clean, well-graded, saturated surface dry, have low absorption, high density and comply with ASTM C33, size number 8 per table 2.
APPLICATION
The prepared grout 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. Grout having been prepared but not placed within one (1) hour after preparation shall be discarded. Prepared grout shall be agitated until use. Several hours after placement of grout (depending on ambient temperatures) forms may be removed and exposed grout shoulders may be trimmed or shaped to desired finish.
Dry pack application: Refer to the Sika® Cementitious Grouting Method Statement.
CURING TREATMENT
As per ACI 308 recommendations for cement concrete, curing is required. To achieve performance consistent with Technical Data, curing must be provided by recognized curing 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. Usage of Sika® Ultracure DOTTM or NCFTM wet curing blankets is also strongly recommanded. Curing must commence immediately after placing and finishing. Protect freshly applied grout from direct sunlight, wind rain and frost.
CLEAN UP
Clean all tools and equipment immediately after use with water. Once hardened, material can only be removed manually or mechanically.

Use a minimum amount of water consistent with placeability requirements. After all dry product has been added to the water, continue mixing for three (3) minutes.
Minimum application thickness (neat without additional aggregate) is 25 mm (1 in), while the maximum application thickness (neat without additional aggregate) is 150 mm (6 in). Thicker applications are possible with the addition of suitable aggregate.
Maintain wet grout, ambient and substrate temperatures between +5 °C and +32 °C (41 - 89 °F) for a period of 72 hours after placing, unless using Sikacem® Accelerator in mix (refer to Technical Data section).
For best results, condition product to temperatures ranging from +18 to +29 °C (65 to 84 °F) prior to mixing and installation. Lower temperatures may result in slower strength development and longer cure times.
Initial set time is 4 h to 5 h 30 min, and the final set is 5 to 7 hours.
