Ultra-Stick Shotcrete
Dry Application

Description

Ultra-Stick Shotcrete dry is a pre-blended, accelerated dry shotcrete containing carefully selected components. Ultra-Stick Shotcrete has greatly enhanced shooting characteristics and physical properties.

Uses

In the dry process, Ultra-Stick Shotcrete is pneumatically conveyed dry or predampened through an Aliva dry machine or a Thiessen Team Predampener and water is added at the nozzle. The shotcrete impacts the surface at high velocity resulting in a well compacted, high quality shotcrete with excellent bond. Some common uses include:

  • Slope stabilization
  • Initial and secondary tunnel support
  • Structural linings
  • Concrete rehabilitation

Ultra-Stick Shotcrete Dry may be used in combination with steel fiber or poly fiber reinforcement (in super sacks only) to enhance load carrying capacity and with non-caustic shotcrete accelerators to provide high strengths and fast set times. It can be blended to meet ACI 506 gradation #1 or #2.

Advantages

Stickiness: Bagged Ultra-Stick Shotcrete has vastly improved cohesion characteristics compared to conventional shotcrete. This stickiness saves time and money because:

  • Sagging and sloughing are eliminated
  • Thick layers can be applied in a single pass in both the vertical and overhead orientations. This increase shooting efficiency. Passing over work two or three times to achieve a certain thickness is no longer required
  • Bagged product has the admixtures including fiber already in the mix.
  • Ultra-Stick Dry Application requires lower equipment start-up costs.
