A flexural cyclic loading machine has been developed for an investigation into the fatigue characteristics of concrete containing small proportions of small steel fibres. Deterioration of large concrete beams caused by cracking was monitored by observation of changes in central deflection, variation of strain across the beam depth, midspan, electrodynamic modulus and ultrasonic pulse velocity. Typical results derived from ultimate load tests whose duration ranged from 0 02 seconds to several minutes and long term fatigue tests have been provided.
