title = "Differences between the fatigue behaviour of high-strength grout and high-strength concrete",
abstract = "High-strength grouts are commonly used in the wind energy industry, where they are exposed to high cyclic loading. The latest scientific results (e.g. Elsmeier et al. 2016) indicate a different fatigue behaviour of high-strength grout compared to high-strength concrete. The main differences between the composition of high-strength grout and high-strength concrete is the paste content and the maximum grain size. Fatigue tests with two high-strength grouts and one high-strength concrete were carried out to investigate differences in the fatigue behaviour. The high-strength grouts have the same paste content but a different maximum grain size. The high-strength concrete has a lower paste content and a larger maximum grain size. Within the scope of this paper, the difference in the fatigue behaviour is analysed using the numbers of cycles to failure, the temperature development, the hysteresis loops and the dissipated energy. Results concerning differences in the fatigue behaviour between high-strength grout and high-strength concrete are presented in this paper. The results are analysed particularly regarding the influence of the paste content and the maximum grain size.",
