The effect of alkali-silica reaction on the fatigue behaviour of plain concrete tested in compression, indirect tension and flexure

摘要

The fatigue strength of concrete is an important factor in the design of many structures. However, the behaviour of concrete under indirect tensile repeated load has never been clarified to date by researchers. Therefore on of the objectives of this investigation was to study the effect of alkali-silica reaction (ASR) on the fatigue behaviour of concrete tested in flexure as well as under repeated indirect tensile load. The other objective of this investigation was to study the effect of ASR on the fatigue behaviour of plain concrete tested in compression. The latter is of particular importance to the structural engineer. Its importance lies in that it is a quality control test as well as a basic physical property for use in theoretical analysis of concrete structures.
