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 wetmix shotcrete, which may be attributed in the main to the lower fiber rebound associated with the wet-process.
