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

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.
