Mechanical and microstructural properties of steel fibre reinforced cement-based materials

Abstract

The prime aim of this thesis was to examine the comparative mechanical properties of plain and steel-fibre reinforced cement-based materials, and attempt to interpret the behaviour through microstructural considerations. Based on previous studies of steel fibre reinforced cements, an examination of the uniaxial, static compressive properties was initially undertaken. These investigations were then extended to the fatigue situation. A knowledge of the properties in compression can be justified in view of the fact that concrete is extensively designed based on its compressive properties. However, in order to attempt to understand more fully the various factors contributing to steel-fibre reinforcement in cement-based materials, it is considered necessary to carry out tests in direct tension. Another aim was therefore to develop and utilise such a suitable method for comparative purposes under both static and fatigue conditions.
