For Applications Requiring Rapid Set Times
Flash-Set Shotcrete is a pre-blended, dry shotcrete based on modified hydraulic cement for a very rapid set. Flash-Set Shotcrete also has greatly enhanced shooting characteristics and physical properties due to specially selected admixtures.
Flash-Set Shotcrete is not intended for use as a structural support lining. Its unique properties make it ideal as a sealing coat to enable additional shotcrete to be applied.
- Flash-Set Shotcrete is designed to be used with the Dry Process. It was specifically developed for the following applications:
- Sealing a raveling surface.
- Spraying onto wet areas to contain and direct the water flow.
- Providing “instant” temporary support in wet or unconsolidated ground.
- Flash-Set Shotcrete may be used in combination with steel fiber reinforcement to enhance load carrying capacity. It can be blended to meet ACI 506 gradation #1 or #2.
- Instant Set: Flash-Set Shotcrete sets within moments of application to create a sealing membrane and provide limited immediate support.
- Stickiness. “Flash-Set” Shotcrete has vastly improved cohesion characteristics compared to conventional shotcrete Rebound is significantly reduced, resulting in lower material usage
- Rebound is significantly reduced, resulting in lower material usage.
- Sagging and sloughing are eliminated.
- Physical properties: Silica fume in “Flash-Set”
- Shotcrete creates a higher strength shotcrete with low permeability and excellent freeze/thaw durability.
- Resistance to water washout: “Flash-Set” Shotcrete in the plastic state has tremendous resistance to washout by flowing water. This allows it to be applied to moderately wet surfaces.
