FX-350

DESCRIPTION:

FX-350 Shotcrete Accelerator (Gunite) is a chloride-free accelerator for use in (pneumatically-applied cement mortar or concrete) shotcrete. FX-350 Shotcrete Accelerator (Gunite) is supplied in powder or liquid form. The powder is used with dry-line equipment. The liquid is used with wet or dry process, or where the fine and coarse aggregate is wet.

ADVANTAGES:

Provides Rapid Strength Gain—FX-350 Shotcrete Accelerator (Gunite) achieves structural strength more rapidly under any conditions.

Resists Blasting—Initial set is achieved in 3 to 5 minutes; structural strength is achieved in a matter of hours with FX-350 Shotcrete Accelerator (Gunite), which permits sealing and lining to follow closely behind tunnel headings.

Leak Control—Accelerating the set with FX-350 Shotcrete Accelerator (Gunite) will seal damp and leaking rock or concrete. A flash set can be obtained by using greater amounts of FX-350 Shotcrete Accelerator (Gunite) in powder form. FX-350 liquid can be used directly from the drum to achieve a flash set if desirable.

MIXING:

FX-350 Shotcrete Accelerator Liquid is used at the rate of 1 quart to one gallon per sack of cement. FX-350 Shotcrete Accelerator Powder is used at one to three pounds per sack of cement, depending on requirements. The proper proportion should be determined on site with the materials, mix and temperatures, to produce the best economy based on requirements. Type I and Type III cement produce faster sets than Type II.

APPLICATION:

FX-350 Shotcrete Accelerator Liquid—is added to the mix water, or at the mixing nozzle, FX-350 liquid is used with either wet or dry process.

FX-350 Shotcrete Accelerator Powder—the powder form should be used only in dry line operations. Add the necessary amount to the mix prior to loading the mix into the hopper or to the equipment used for shotcreteing (gunite).

FX-350 Shotcrete Accelerator Powder may be premixed with gunite if all other materials are moisture free.
