Abstract: This report compares and contrasts the effects of process on the performance of fiber reinforced shotcrete. Using Optimet® steel fibers for reinforcement, the paper discusses the causes for the higher penetration resistance in dry-mix shotcrete, while highlighting the differences in composition and rebound during the fresh state. A strong influence of the spray process is witnessed on the hardened properties under both compression and flexure. While dry-mix shotcrete was found to be stronger in compression, it was relatively weaker under flexure. The improvement in flexural toughness through fibers was more pronounced in wet-mix shotcrete, which may be attributed in the main to the lower fiber rebound associated with the wet-process.
