PRODUCT DESCRIPTION
Tasir Special Grout SR is a sulfate resistant, cement-based, nonmetallic, non-shrink grout for applications requiring sulfate resistance. When tested in accordance with ASTM C 827, Tasir Special Grout SR exhibits positive expansion. Tasir Special Grout SR meets the performance requirements of ASTM C 1107-02 Grades A, B and C, ASTM C 1107-07, and CRD-C 621-93 specifications for non-shrink grout over a wide temperature range, 40°F - 90°F (4°C - 32°C).
ADVANTAGES
Air release technology per ACI 351.1 R
Sulfate resistance
Moderate heat of hydration
95% Effective Bearing Area (EBA) is typically achieved following proper grouting procedures
Permanent support for machinery requiring precision alignment
Does not contain gas generating additives, such as aluminum powder
Non-shrink from the time of placement
USES
Deep large volume pours
Grouting of machinery baseplates to maintain precision alignment in areas of sulfate attack
Non-shrink grouting of structural steel and precast concrete
Installation of anchors and dowels
Support of tanks and vessels
Repair of concrete in confined areas
PACKAGING AND YIELD
Tasir Special Grout SR is packaged in heavy-duty, polyethylene lined bags and is available in 50 lb. (22.7 kg) units yielding approximately 0.45 cubic feet (12.7 liters), or 100 lb (45.4 kg) units yielding approximately 0.90 cubic feet (25.5 liters) of hardened material at maximum water content.
SHELF LIFE
One year in original unopened packaging when stored in dry conditions; high relative humidity will reduce shelf life.

PLACEMENT GUIDELINES
1. SURFACE PREPARATION: All surfaces in contact with Tasir Special Grout SR shall be free of oil, grease laitance and other bond- inhibiting contaminants. Concrete should be mechanically roughened to coarse aggregate exposure to maximize bond. A Concrete Surface Profile (CSP) of 8-10 in accordance with ICRI Technical Guideline 310.2R-2013 is recommended. Presoak concrete surfaces for 8 to 24 hours, continuously and consistently, via wet rags, wet burlap, ponding or similar method.
2. FORMWORK: Formwork shall be constructed of rigid non-absorbent materials, securely anchored, liquid-tight and strong enough to resist forces developed during grout placement. The clearance between formwork and baseplate shall be sufficient to allow for a headbox. The clearance for remaining sides shall be one to two inches (25 - 50 mm). Areas where bond is not desired must be treated with form oil, paste wax or similar material. Isolation joints may be necessary depending on pour dimensions. Contact Five Star Products'Engineering and Technical Service Center for further information.
3. MIXING: Mix Tasir Special Grout SR thoroughly for approximately four to five minutes to a uniform consistency with a mortar mixer (stationary barrel with moving blades). A drill and paddle mixer is acceptable for single bag mixes. For optimum performance, condition between 40°F and 90°F (4°C and 32°C). Mix Tasir Special Grout SR with 3 to 5 quarts potable water per 50 lb. bag. Working time is approximately 45 minutes at 70°F (21°C). Follow printed instructions on the package. Always add mixing water first to mixer followed by grout.
4. PLACEMENT PROCEDURES: Tasir Special Grout SR may be dry packed, poured or pumped into place. Minimum placement thickness for Tasir Special Grout SR is one inch (25 mm). For pours over six inches (150 mm) in depth, Tasir Special Grout SR should be extended with a clean damp coarse aggregate meeting the requirements of ASTM C 33.
