Sika Grout 212 - Non-Shrink Grout
Sika Grout 212 is cementitious grouts containing carefully formulated blends of natural aggregates and other materials, plus Sika admixtures which enable them to achieve high early age strengths. Sika Grouts have been designed to incorporate a two-stage process that counteracts the effects of shrinkage often associated with cement grouts.
Sika Grouts contain materials that provide positive expansion in the plastic phase and shrinkage compensation once hardened.
Sika Grouts are normally used in details where the material can be confined and restrained during placement and curing to optimise these characteristics.
Sika Grout 212 is a one component grout and only requires the addition of clean, fresh water.
Sika Grout 212 is ideal for many types of structural grouting applications. It can be mixed at different stages of fluidity to produce the desired level of workability. Add the required amount of water for:
- Rammable dry pack material.
- Trowel applied medium flow mortar.
- Pourable high flow grout. Typical applications for Sika Grout 212 are:
- Under machine foundations and base plates.
- General cavities, voids and recesses
- Grouts for anchor bolts, ground anchors, rods, etc.
- Reinforcement ducts in the connection detail between precast columns and beams
Sika Grouts offer the following advantages:
- Positive shrinkage compensation.
- High early age strength development.
- High final strengths.
- Excellent substrate adhesion.
- Adjustable consistency.
- High flow characteristics.
- Controlled bleeding and segregation while plastic.
- Ideal for use in pre-packed aggregate systems of repair - Sika Grout 215.
- Non-corrosive, non-toxic.
- Impact and vibration resistant.
- Increased resistance to aggressive liquid penetration when hardened
HOW TO USE:
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.
manner 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.
low absorption, high density and comply with ASTM C33, size number 8 per table 2.
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.
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.
- 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.
- Maintain wet grout, ambient and substrate temperatures between 5 - 32 °C (41 - 89 °F) for a period of 72 hours after placing, unless using Sikacem® Accelerator in mix (refer to Technical Data section).
- SikaGrout®-212 must be protected from freezing during setting.
- Minimum application thickness (neat without additional aggregate): 25 mm (1 in).
- Maximum application thickness (neat without additional aggregate): 150 mm (6 in). Thicker applications are possible with the addition of suitable aggregate. Contact Sika Canada.
- For anchor bolt/dowel grouting, hole diameter should be 25 mm (1 in) greater than bar diameter.
- Anchor bolt/bar holes should be pre-dampened for a period of one (1) hour prior to grouting. Holes must be in saturated surface dry (SSD) condition at time of grouting.
- Do not use as a patching or overlay mortar or in unconfined areas.
- Use only potable water.
- Extending with aggregates will reduce compressive and flexural strengths. Dimensions and grading of aggregates will influence effect on physical properties; pre-testing is recommended.3-440
