It is truly paramount to recognize the diversity of solutions available because of the versatility that shotcrete offers. Shotcrete placement provided more efficient, sustainable and durable concrete solutions in these two cases than could have been achieved with a form-and-pour approach.
Early Age Strength Testing for Shotcrete: 2024
For improved safety in tunneling and mining projects that use shotcrete for ground support, early shotcrete strength should be evaluated by testing. Based on their range of effectiveness, two procedures stand out: The new Hilti BX 3-SCT stud driving method and the beam end tester.
Geohazard Mitigation: Why Shotcrete?
To improve safety and mitigate the risks of rockfall events along I-65 in Giles County, TN, GeoStabilization partnered with the Tennessee Department of Transportation and a local construction company.
Rapid Strength Gain Dry-Mix Shotcrete: A Unique Solution for Highly Complex Projects
The construction industry must embrace new technologies and innovations to address today’s challenges. With its unique features, shotcrete stands out as a placement solution, meeting the most stringent project standards and offering unmatched benefits compared to traditional form-and-pour concrete.
The Application of Shotcrete in Shafts: Work Preparation and Construction Based on Various Projects in Central Europe
Shotcrete shafts often present unique challenges for construction projects. In many cases the construction method is different from the one used in the main tunnel (often using a TBM), presenting challenges recruiting experienced and certified personnel for the shaft works.
Modelling the Service Life of Structures with Cast-in-Place Concrete vs. Wet-Mix Shotcrete
When properly designed and applied, wet-mix shotcrete provides equal or increased service life for reinforced concrete structures compared to cast concrete.
Polymer Rubber Gel Technology: High-Performance Waterproofing for Shotcrete and Blind-Side Applications
The innovative GTS Polymer Rubber Gel waterproofing systems are proven and effective for underground construction applications.
Summary of ‘Guideline on the Applicability of Fiber-Reinforced Shotcrete for Ground Support in Mines’
This guide examines and provides a description of the common testing methods used for FRS and how to interpret the information generated for ground support in mines.
Updated Fiber-reinforced Shotcrete Testing Standard — Faster, Easier and Better!
The updated fiber-reinforced shotcrete testing standard in underground projects provides not just significant cost savings, but just as critical, helps us to significantly reduce the carbon impact of the underground construction industry and provide for a better environment and future for us all.
