PRODUCT DESCRIPTION

Tasir® Structural Concrete V/O is a high strength, rapid setting, one component, permanent concrete repair material for vertical and overhead structural repairs.Tasir® r Structural Concrete V/O produces a repair which is dimensionally stable, develops an integral bond to existing concrete, and restores structural integrity within hours of placement. Tasir® Structural Concrete V/O provides increased corrosion protection to steel reinforced structures with migrating corrosion inhibitor technology and very low chloride ion permeability. Moisture sensitive coatings can be applied in 8 to 24 hours. This specialized version of Tasir®  Structural Concrete V/O is compliant with NRC 10CFR50 Appendix B and ASME NQA-1 Quality Programs.

PLACEMENT GUIDELINES

1. SURFACE PREPARATION: All concrete surfaces in contact with Tasir® Structural Concrete V/O shall be free of oil, grease, laitance, and other contaminants. All concrete surfaces must be clean, sound and rough to ensure a good bond. Mechanically roughen concrete surfaces in accordance with ICRI Technical Guideline 03732 to a minimum concrete surface profile roughness (CSP) 6 or greater. Remove all oxidation from exposed reinforcing steel. A perimeter edge and minimum depth of 1/4 inch (6 mm) should be provided for a durable repair. Featheredging is not desirable. Soak concrete surfaces prior to application with liberal quantities of potable water, leaving the concrete saturated and free of standing water. Surfaces shall be conditioned to between 40°F and 90°F (5°C and 32°C) at time of placement.

2. MIXING: Mix Tasir® Structural Concrete V/O thoroughly for approximately three to four 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. MixTasir® Structural Concrete V/O with 3 to 4 quarts potable water per 50 lb. unit. Working time is approximately 15 minutes at 70°F (21°C). Follow printed instructions on the package. Start by adding the minimum amount of pre-measured water to mixer and, after mixing for three to four minutes, adjust consistency as required to achieve non-sag consistency.

3. PLACEMENT PROCEDURES: Firmly work a small amount of Tasir® Structural Concrete V/O into concrete surface with a trowel, taking care not to leave air pockets. Application is from one side of the repair to the other, filling the repair to the desired level. For multiple lift applications, contact Five Star Products'Engineering and Technical Service Center at +86-571-87569602. Finish as necessary.

4. POST-PLACEMENT PROCEDURES: Tasir® Structural Concrete V/O shall be kept continuously wet for at least 30 minutes after final set. Protect from freezing until a compressive strength of at least 1,000 psi (6.9 MPa) is 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

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

• Temperature of materials, equipment and surfaces must be between 40°F and 90°F (5°C and 32°C) at time of placement. For cold and hot weather placement, consult theTasir® installation guidelines.

• Substrate shall be free of frost and ice.


CAUTION

Contains cementitious material and crystalline silica. The 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.
