Frequently Asked Questions
What size is Stratarock FRPC CH?
The unit is a 65 lb bag and a 1 gallon jug of liquid additive. One unit yields approximately 0.53 cu ft.
What work uses Stratarock FRPC CH?
Horizontal toppings or repairs on deteriorated concrete, pouring pedestals and curbs, rebuilding equipment bases, and recovery-boiler concrete repairs. Above or below grade. High-strength repairs not exposed to acid.
What compressive strength does Stratarock FRPC CH have?
Typical laboratory compressive strength (ASTM C109 Modified) is 4,062 psi at 1 day, 6,850 psi at 3 days, 7,500 psi at 7 days, and 8,670 psi at 28 days. Expect reasonable variation under field conditions.
What coating wait does Stratarock FRPC CH have?
Surfaces can be coated in 48 hours. For proper curing, keep moist for 3 days with a fine mist, wet burlap, or plastic. A curing compound meeting ASTM C309 also works; curing compounds may need to be mechanically removed before coating.
What bond strength does Stratarock FRPC CH have?
Typical laboratory bond strength is 1,650 psi at 28 days (ASTM C882 Modified). Split tensile is 500 psi at 28 days (ASTM C496). Flexural is 960 psi at 28 days (ASTM C293).
What freeze-thaw result does Stratarock FRPC CH show?
Typical laboratory freeze/thaw is no damage at 100 cycles (ASTM C666). 28-day shrinkage is 0.03. Shelf life is 1 year in unopened original bags kept dry at 75 F.
