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 3½ to 5½ 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. Refer to Tasir® Technical Bulletin “Cement Grout Aggregate Extension” for guidelines. For more detailed placement procedures, see Tasir® INSTRUCTION.

5. POST-PLACEMENT PROCEDURES: Tasir® Special Grout SR shall be wet cured for a minimum of three days, or coated with an approved curing compound meeting the requirements of ASTM C 309 after a minimum 24 hour wet cure. In-service operation may begin immediately after the required grout strength has been reached.

NOTE: PRIOR TO APPLICATION, READ ALL PRODUCT PACKAGING THOROUGHLY. For more detailed placement procedures, refer to Tasir®  installation guidelines or call Tasir® Products'Engineering and Technical Service Center at +86-571-87569602.


CONSIDERATIONS

At time of placement, if temperatures of equipment and surfaces are not between 40°F and 90°F (4°C and 32°C), refer to Tasir® INSTRUCTION for cold and hot weather grouting procedures or contact Tasir® Products'Engineering and Technical Service Center at +86-571-87569602.

• Substrate shall be free of frost and ice.

• Never exceed the maximum water content stated on the bag.

• Construction practices dictate concrete foundation should achieve its design strength before grouting.

• Tasir® Special Grout 150 should attain a minimum compressive strength of 1,000 psi (6.9 MPa) before being exposed to freezing temperatures.


CAUTION

Contains cementitious material and crystalline silica. International Agency for Research on Cancer has determined that there is sufficient evidence for the carcinogenicity of inhaled crystalline silica to humans. Take appropriate measures to avoid breathing dust. Avoid contact with eyes and contact with skin. In case of contact with eyes, immediately flush with plenty of water for at least 15 minutes. Immediately call a physician. Wash skin thoroughly after handling. Keep product out of reach of children. PRIOR TO USE, REFER TO SAFETY DATA SHEET.
