FREQUENTLY ASKED QUESTIONS
Rapid Set Low-P FA1 Cement is a specialty formulated Rapid Set cement when incorporated into a concrete, the performance includes very low-permeability, high durability, ASR resistant, freeze thaw resistance and corrosion resistance. These attributes are highly desirable for structural repairs and bonded overlays in exterior and harsh environments (i.e. bridge decks, marine docks and parking garages).
Low-P FA1 Cement concretes can be used in fast-track bridge deck overlays, pavement repairs and general projects where low chloride ion permeability, corrosion resistance, and fast strength gain are desired.
Working time will vary depending on ambient temperatures. In cooler ambient temperatures, the working time will be 20 minutes, whereas in hot temperatures, it will be 10 minutes. Retarders may be used to extend working time 20 to 40 minutes. Contact your CTS representative for more information.
Low-P FA1 concrete can be applied in ambient temperatures between 40РF to 95РF. However, the existing surface and substrate temperatures must also be considered. In hot weather, cooling the substrate may needed to slow the hydration process. For freezing temperature applications, please contact your local CTS Cement Representative for more information.
Low-P FA1 Cement can be mixed with conventional equipment, but volumetric mixers are typically used for large placements. Direct deposit, conveyors and buggies can be used. Pumping will require additional retarders and machinery. Placing with roller screeds, hand strikes and self-propelled deck finishers are commonly used. Truss screeds can be used in small area applications. Scrub coating is not required for applications where proper surface preparation has been established. Traditional finishing tools are required.
