INFLUENCE OF FIBER GEOMETRY IN STEEL FIBER REINFORCED DRY-MIX SHOTCRETE

The details are described of a test program which assessed the influence of fiber geometry on the rebound characteristics and hardened shotcrete properties. The results relating to absorption, permeable voids, fiber rebound, strengths, and flexural toughness are tabulated and discussed. It was found that the extent of fiber rebound during shotcreting appears to be directly related to the specific projected fiber area. For the test system used in this study, the lower Toughness Indices are not sensitive either to fiber geometry or to fiber volume fraction.
