FATIGUE STRENGTH OF POLYPROPYLENE FIBER REINFORCED CONCRETES. FIBRE REINFORCED CEMENTS AND CONCRETES: RECENT DEVELOPMENTS. PROCEEDINGS OF AN INTERNATIONAL CONFERENCE HELD AT THE UNIVERSITY OF WALES, COLLEGE OF CARDIFF, SCHOOL OF ENGINEERING, UNITED KINGDOM, SEPTEMBER 18-20, 1989

This paper presents the results of an experimental investigation to determine the flexural fatigue strength of concrete reinforced with three different concentrations of fibrillated polypropylene fibers. The properties of fresh and hardened concretes with and without fibers are compared. The test results indicate that there was no balling or tangling of fibers during mixing and placing. There was an appreciable increase in post-crack energy absorption capacity and ductility due to addition of fibers. When compared to corresponding plain concrete there was a significant increase in the flexural fatigue strength and the endurance limit (for two million cycles). The static flexural strength increased after being subjected to fatigue loading.(A) For the covering abstract of the conference see IRRD 827953.
