SPRAYED CONCRETE CONFERENCE 2021

On 21 and 22 January 2021 the Shotcrete Conference will take place for the 13th time in Alpbach in Tyrol, Austria. The German-language event in the Congress Centrum Alpbach will be organised for the first time by the Austrian Construction Technology Association (ÖBV).

• Research programmes in Norway and Austria
• Steel fibre shotcrete for TBM driving
• Permanent inner shells (single shell and on foil sealing)
• Sprayable seals
• Tunnel repair and tunnel brightening
• Shotcrete delivery and layer formation
• Visualisation of imperfections and proof of the accelerator content
• Ultra-high performance fibre shotcretes for refurbishment work
• Thermally stressed shotcrete and shotcretes in fire protection
• The right choice of retarders for wet sprayed concretes
• Sulphate and thaumasite attack
• Sequence of early hydration of accelerated sprayed concretes of different composition
• Restoration of historical arched vaults
