Corrosion of embedded steel reinforcement is a threat to all types of reinforced concrete, leading to cracking, spalling, and a shortened service life of thestructure.
Underground at Mines
In 2011, realizing a need to identify a unifying program dedicated to underground construction and tunneling education across campus, Colorado School of Mines established the Center for Underground Construction andTunneling,
East Side Access Project
In May 2014, Superior Gunite was issued a subcontract by the Michels Corporation to shoot approximately 2000 yd3 (1500 m3) of shotcrete for overbreak build back on the arches of the East Side Access Project?
Modeling of Load-Bearing Behavior of Fiber-Reinforced Concrete Tunnel Linings
The use of fiber-reinforced concrete (FRC)?with steel or macro-synthetic fibers?has technical and economic advantages that primarily stem from the fact that fibers transform the post-cracking behavior
Lining Raise-Bore Shafts
When raise boring is used, a circular excavation is roduced either between two existing levels in an underground mine or between the surface and anexisting level in a mine.
Innovative Shotcrete Technologies for Advancement in Tunneling
Sprayed concrete (shotcrete) is a well-established and proven component of ground support systems worldwide.
