PRODUCT DESCRIPTION

Tasir® -Strcon03 is a normal setting, one component, used for pourable and pumpable repairs of concrete structures. Tasir® -Strcon03 may be extended with coarse aggregate for large volume repairs and foundation upgrades. Tasir® -Strcon03 provides increased corrosion protection of steel reinforced structures with migrating corrosion inhibitor technology and very low chloride ion permeability.

PACKAGING AND YIELD

Tasir® -Strcon03 is packaged in heavy-duty polyethylene lined bags and is available in 50 lb. (22.7 kg) units yielding approximately 0.40 cubic feet (11.3 liters) at maximum water, or 0.60 cubic feet (17.0 liters) with a 70% extension using 3/8” pea gravel. Tasir® -Strcon03 is also available in 3,000 Lb. (1,360 Kg) bulk bags.


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 horizontal and vertical concrete surfaces in contact with Tasir® -strcon03 shall be free of oil, grease, laitance, and other contaminants. All horizontal and vertical 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 one inch (25 mm) should be provided for a durable repair. Feather edging is not desirable. Soak concrete surfaces prior to application with liberal quantities of potable water, leaving the concrete saturated and free of standing water, or use Tasir® -Bonding Adhesive. Surfaces shall be conditioned to between 40°F and 90°F (5°C and 32°C) at the time of placement.

2. FORMWORK: Formwork shall be constructed of rigid non-absorbent materials, securely anchored, liquid-tight and strong enough to resist forces developed during placement. Areas where bond is not desired must be treated with form oil, paste wax or similar material. Joints may be necessary depending on pour dimensions. Any existing joints within the repair area should be maintained. Contact the Tasir Products’ Engineering and Technical Service Center for further information.

3. MIXING: Wet down mortar mixer (stationary barrel with moving blades) before using and drain excess water. A drill and paddle mixer is acceptable for single bag mixes. With the mixer running add approximately 80% of the pre-measured potable water (total water content is 2¼ to 3 quarts potable water per 50 lb. unit) to the mixer. While mixing, slowly add Tasir® -Strcon03 and mix to a uniform consistency for three to four minutes. Adjust consistency if necessary, but do not exceed maximum water content stated on the package or an amount that will cause segregation. Add clean, damp course aggregate meeting ASTM C 33 before final water adjustment. Do not mix more material than can be placed within 60 minutes.

4. PLACEMENT PROCEDURES: Whenever possible, place Tasir® -Strcon03 full depth from one side of the repair to the other. To ensure optimal bond development, firmly work material into substrate. Placement should be continuous to prevent cold joints between pours. Finish as necessary.

SPECIAL CONDITIONS: For use in cold temperatures, Tasir® -Strcon03 must be maintained at a temperature of at least 45°F (7°C). Protect from freezing until a compressive strength of at least 1,000 psi (6.9 MPa) is obtained. Faster strength gain will occur when the Tasir® -Strcon03 and mixing water have been conditioned to a higher temperature prior to placement. In hot temperatures, Tasir® -Strcon03 should be kept as cool as possible, but not exceeding 90°F (32°C).

5. POST-PLACEMENT PROCEDURES: Tasir® -Strcon03 shall be protected from moisture loss until initial set, then immediately coated with an approved curing compound meeting water retention properties of ASTM C 309 or continuously wet cured for a minimum of three days. In- service operation may begin immediately after the required 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 Products'Engineering and Technical Service Center at  +86-571-87569602.


CONSIDERATIONS

● Never exceed the maximum recommended amount of mixing water as stated on the package or add an amount that will cause segregation.

● Under high evaporative conditions, an evaporation retarder or water fogging must be used prior to curing.

● For ready-mix truck mixing guidelines, contact  Products'Engineering and Technical Service Center at +86-571-87569602.


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.
