PACKAGING AND YIELD

Tasir® -SCG is packaged in heavy-duty polyethylene lined bags and is available in 50 lb. (22.7 kg) units yielding approximately 0.39 cubic feet (11.0 liters) at maximum water. Tasir® -SCG is also available in 3,000 lb (1,360 kg) bulk sacks for large volume applications.


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® -SCG shall be free of oil, grease, laitance, and other contaminants. Concrete 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. A perimeter edge and minimum depth of 1/4 inch (6 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. Surfaces shall be conditioned to between 45°F and 90°F (7°C and 32°C) at the time of placement.

2. MIXING: Wet down mortar mixer (stationary barrel with moving blades) before using and drain any excess water. A drill and paddle mixer is acceptable for single bag mixes. Add the minimum amount of premeasured potable water (2¼ quarts per 50 lb. unit) as stated on product packaging to mixer . While mixing, slowly add  Tasir® -SCG and mix to a uniform consistency for three to four minutes. To achieve desired consistency for wet process application, add remaining water as necessary. Do not exceed maximum water content as stated on product packaging or add an amount that will cause segregation. Mix thoroughly for approximately five minutes. Do not mix more material than can be placed within 30 minutes. Do not retemper the mix by adding additional water.

3. METHODS OF PLACEMENT: Apply Tasir® -SCG to full design thickness whenever possible. Repair material is applied in layers just thick enough to prevent sagging. Direct nozzle perpendicular to surface and rotate in a series of circular patterns, filling inside corners first. Tasir® -SCG should emerge from the nozzle in a uniform, uninterrupted flow. Finish to desired texture with screed, float, trowel, or brush. To obtain optimum results, repair shall be installed to full depth without allowing intermediate lifts to harden. Where placement depth and patch geometry require installation in lifts, subsequent lifts may be placed after repair material has reached initial set. Applied material shall be given a raked finish to ensure proper adhesion between lifts. Repair material must be kept continuously wet from time of hardening until installation of succeeding lifts. For more detailed application and curing procedures, refer to ACI 506R-05, Guide to Shotcrete Report.

SPECIAL CONDITIONS: For use in cold temperatures, Tasir® -SCG 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® -SCG and mixing water have been conditioned to a higher temperature prior to placement. In high temperatures, Tasir® -SCG should be kept as cool as possible, but not exceeding 90°F (32°C). Ice cold water should be used for mixing to help maintain sufficient working time.

4. POST-PLACEMENT PROCEDURES: Tasir® -SCG shall be coated with an approved curing compound meeting the water retention properties of ASTM C 309 immediately after finishing. Protect from excessive evaporation prior to set.

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


CONSIDERATIONS

● Never exceed the maximum water content as stated on the package or mix to a consistency which will cause segregation.

● Temperature of surfaces must be between 45°F and 90°F (7°C and 32°C) at time of placement. For cold and hot weather placement, call Tasir Products'Engineering and Technical Center at +86-571-87569602.

● Repair material shall be protected from freezing until it reaches 1,000 psi (6.9 MPa).

● Placement shall be continuous to avoid cold joints.


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.
