Applications

Shotcrete

Silica-fume Shotcrete – delivers greater economy, greater time savings and more efficient use of sprayed concrete.  Silica fume produces superior shotcrete for use in rock stabilization, mine tunnel linings, and rehabilitation of deteriorating bridge and marine columns and piles.  Greater bonding strength assures outstanding performance of both wet and dry process shotcreting with less rebound loss and thicker applications with each pass of the shotcrete nozzle.  Some performance characteristics are:

• Reduction of rebound loss up to 50%
• Improved production time, with one-pass application thicknesses up to 12 inches
• Higher bonding strength
• High electrical resistivity and low permeability
• High compressive and flexural strengths

Above or below ground shotcreting routinely employs silica fume for efficiencies in build-up thickness and material rebound.
