Abstract

Concrete pavements under repetitive loading prematurely fail due to growth and propagation of micro cracks present in the matrix. Incorporation of steel fibers in the concrete matrix helps arrest growth and propagation of cracks and enhances strength, fracture toughness and elastic modulus. The present investigation attempts to study the behavior of steel fiber reinforced concrete of grade M30. Effect of partial replacement of cement with fly ash to the extent of 20% has also been investigated. Static flexural test, compression tests and split tensile tests have been conducted on specimen prior to flexural fatigue test at a frequency of 2 Hz at various stress levels. S-N diagrams have been plotted and fatigue equations have been proposed based on results of experimental investigation.
