Shotcrete: Systematically Sprayed Support
From being a niche system even 20 years or 30 years ago, shotcreting has developed to be one of the most important rock-support methods available to the mining and tunneling industries. As Lars Balck, formerly a SVP at Crom LCC, explained in a comprehensive review of the technology's history and guidelines published in a recent edition of Shotcrete magazine, what is now referred to as dry-mix shotcrete can trace its antecedents back to the invention of the gunite gun in 1910. The cement gun was a breakthrough for concrete construction. Mortar could now be conveyed long distances and produce high-strength concrete. Today, both wet- and dry-mix systems of shotcrete emplacement have applications in rock support. Introduced in 1955, wet mix has the advantages of being able to achieve better material consistency through off-site mixing, producing less dust, and achieving greater volumes in a given time.
