Containing migrating corrosion inhibitors, produces a repair which is dimensionally stable, develops an integral bond to existing concrete, and restores structural integrity within hours of placement. Application thickness can range from 1/4 inch to 12 inches in a single pour. Five Star Structural Concrete provides increased corrosion protection of steel reinforced structures with migrating cor- rosion inhibitor technology and very low chloride ion permeability. Moisture sensitive coatings can be applied in 8 to 24 hours. • Single component for reliability and ease of use • High three-hour strengths • Very low chloride ion permeability • Fast turnaround times with high 3-hour strengths • High bond strength • Coarse aggregate extension • Very low shrinkage • Excellent freeze/thaw resistance • One product for thin and thick placements • Outstanding corrosion resistance for protection and rehabilitation Applications : • Repair of concrete structures • Rapid machinery foundation rebuilds • Fast repairs for coatings • Concrete floor repairs and overlays • Construction joint repair • Marine and hydraulic structure repairs • Repair of tanks, sumps and curbs Coverage: One bag yields approximately 0.42 cubic feet at maximum water, or 0.60 cubic feet with a 60% extension using 3/8” pea gravel. Specifications : At 70° F. Compressive Strength (ASTM C-109): 3 hrs 2,500 psi 1 day 5,00 psi 7 days 7,000 psi 28 days 8,000 psi Bond Strength (ASTM C-882): 1 day 2,000 psi 7 days 2,500 psi Working Time: 15 min Five Star Structural Concrete No. Size FS SC 50 lb. pail, 36/pallet TRM Description : TRM, Transportation Repair Mortar Fast-Setting, Horizontal Concrete Repair Mortar is a formable, pumpable, pourable, Portland cement-based, microsilica- modified structural repair mortar for deteriorated exterior and interior concrete above, on or below grade. TRM is fast-setting, allowing for foot traffic in as little as 2 hours and vehicular traffic in as little as 6 hours. It also is easy to apply and readily bonds to concrete. The resulting patch has low shrinkage, resists delamination and produces a surface suitable for normal commercial, institutional and multi-unit residential traffic. Applications: • Suitable for overlays and full-depth repairs • Suitable for normal service commercial, institutional and multi- unit residential applications • Use for exterior and interior concrete repair • Typical applications include plazas, parking garages and balconies. Coverage: 0.4 cu. ft. per 50 lb. bag, 9.6 sq. ft. per 50 lb. bag at 1/2” thickness. Installs from 1/2" to 4" neat, and up to 8" when extended with clean, washed pea gravel or 25 lbs bag of aggregate Specifications: The following results were developed under laboratory conditions @ 70 °F.
