American Shotcrete Association
Read MoreWith more than 7,000 cubic yards (5,350 m3) of shotcrete to be used for slope reinforcement in the MesaÂPayson Highway expansion in Arizona, it may be the biggest shotcrete application in the country. The project consists of shotcreting thirteen freshly-cut mountainsides in the Kitty Joe
StructuralInternationalApplication and Testing of Shotcrete
Wolfgang Kusterle
Read MoreIn 1989, the Austrian Concrete Society pub-lished a Guideline on Shotcrete that subse-quently served as a reference work and a contractual basis for shotcrete works in tunnel con-struction in Austria and abroad. Other standards,such as DIN 18551, focused more strongly on shotcrete for concrete repair

UndergroundStructuralThe Use of Steel Fiber-Reinforced Shotcrete for the Support of Mine Openings
Marc Vandewalle
Read MoreWhat separates the support of mining openÂings from the support of similar civil engineering structures is the fact that mine openings have to survive large defonnations as a result of changing stress conditions induced by progressive mining. Steel fibers impart to concrete and shotcrete a
StructuralBig Bad Curves?, Pumping Fiber-Reinforced Wet-Mix Shotcrete
Denis Beaupre and Frederic Chapdelaine
Read MoreMaking good pumpable concrete or wet mix shotcrete is not always easy, especially when fibers are present Adding fibers to ordinary wet-mix shotcrete sometimes re results in nonpalpable or difficult-to-pump concrete. Simply adding superplasticizer 10 fiber-reinforced shotcrete does not always result in a workable mixture.
