摘要：
Recent modern constructions such as wind turbines require improved performance of concrete and grout, while being submitted to continuous cyclic loading during their service life. The application of these materials can be in the foundations, towers and connecting joints in the transition piece in offshore and onshore structures. Therefore this paper is focussed on the compressive behaviour of a high-strength grout. For this purpose, the fatigue behaviour of the grout is quantitively analysed by considering different stress levels and frequencies of loading. The damage mechanisms are identified from analysis of strain development, temperature increase and stiffness evolution. The sources of temperature increase are identified and the resulting induced damage mechanisms are presented. The loading frequency has a significant influence on the deterioration process, demonstrated from strain development and evolution of the secant modulus. Analogies with the compressive fatigue behaviour of high-strength concrete can be carried out. (C) 2020 Elsevier Ltd. All rights reserved.
