STEEL-FIBER-REINFORCED WET-MIX SHOTCRETE: COMPARISONS WITH CAST CONCRETE. TECHNICAL NOTE

The use of shotcrete in new construction and repair and rehabilitation is on the rise. Wet-mix shotcrete is similar in many respects in composition and rheological characteristics to cast-fiber-reinforced concrete; compaction is the primary difference. As part of a larger investigation in steel-fiber-reinforced wet-mix shotcrete, companion specimens were cast using the shotcrete mixes for a direct comparison with shotcrete after hardening. Comparisons were made between shotcrete and cast concrete on the basis of compressive and flexural strengths as well as flexural toughness. Cast concrete had higher compressive strength; shotcrete had higher flexural strength. Flexural toughness data were inconclusive. Authors suggest care when predicting the behavior of shotcrete based on the performance of cast concretes of similar proportions.
