FLEXURAL FATIGUE STRENGTH, ENDURANCE LIMIT, AND IMPACT STRENGTH OF FIBER REINFORCED REFRACTORY 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

Steel fiber reinforced refractory concrete (SFRRC) is a promising material for heat-resistant airfield pavements. This paper presents the results of an investigation carried out to determine the flexural fatigue, endurance limit, and impact strength of SFRRC at 0.5%, 1.0%, and 1.5% by volume of fiber. These properties are compared with the same refractory concrete mix without steel fiber. The fatigue strength of SFRRC increased 61%, 159%, and 199% with 0.5%, 1.0%, and 1.5% by volume of steel fiber, respectively. The endurance limits expressed as a percentage of plain concrete modulus of rupture, increased 60%, 160%, and 200% when reinforced with 0.5%, 1.0%, and 1.5% of steel fiber by volume, respectively. The addition of steel fibers also substantially increased the impact strength of SFRRC at failure.(A) For the covering abstract of the conference see IRRD 827953.
