CCRC 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.

1. PREPARATION: Completely remove or mitigate all obstructions that may hinder proper installation of product prior to commencing work. Ensure all active water flow is diverted or stopped prior to commencing work. Completely remove all loose, delaminated and weak materials including dirt and debris from work area. Prepare pipe surfaces using high pressure water blasting to thoroughly remove all contaminants and bond-inhibiting materials. Severely corroded pipe sections may need replacement. Metal surfaces may be blasted to a near-white finish; concrete surfaces should be mechanically prepared to an ICRI Concrete Surface Profile (CSP) of 6 or greater. Metal surfaces may require treating with a corrosion inhibitor after mechanical surface prep if they will not be repaired immediately.

2. MIXING: Mix via concrete or mortar mixer. A drill and paddle mixer is acceptable for single bag mixes. Start by adding 2 to 2¼ quarts (1.9 to 2.3 liters) water to mixer followed by Tasir®CCRC. Mix for 3 minutes and check consistency. Add remaining water, if necessary, and continue mixing for 1 to 2 minutes. Do not mix more material than can be placed in 30 minutes.

3. METHODS OF PLACEMENT: Pour or pump Tasir® CCRC into place. When pumping, ensure pump is designed to pump concrete or mortars containing coarse aggregate. Install product at full depth along entire length of area being repaired. Level and screed as necessary.

SPECIAL CONDITIONS: For use in cold temperatures, Tasir®CCRC must be maintained at a temperature of at least 45 degree F (7 degree ). 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®CCRC and mixing water have been conditioned to a higher temperature prior to placement. In high temperatures, Tasir®CCRC should be kept as cool as possible, but not exceeding 90 degree F (32 degree ). Ice cold water should be used for mixing to help maintain sufficient working time.

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 Center at +86-571-87569602.

● Temperature of surfaces must be between 45 degree F and 90 degree F (7 degree and 32 degree ) 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).

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.
