Fiber-Reinforced Shotcrete: Comparing the Properties of Dry- and Wet-Mix Shotcrete Reinforced with Steel Fibers

The authors examine both wet- and dry-mix methods of producing steel fiber reinforced shotcrete. Under identical placement conditions, the dry-mix method showed higher fiber and coarse aggregate rebound than the wet-mix. The wet-mix method showed lower compressive and much higher flexural strength than the dry-mix under identical water-cementitious material ratios. This may have been due in part to both aggregate type and coarse aggregate-cementitious material ratio. Wet-mix shotcrete developed both higher fiber efficiency and much higher toughness than dry-mix in regard to a given fiber dosage's flexural toughness.
