Sludge ejection in the foundation of a wind turbine tower fixed by the anchor-ring method and the resulting sludge buildup have been confirmed to cause the undesirable phenomenon of lifting of the tower. Using specimens that model part of a wind turbine foundation, this study investigates the presence of liquid water, differences in W/C, and differences in loading speed, to analyze concrete damage development factors. The results shows that penetration of liquid water from rainfall and snowfall produces a wedge effect, breakdown of the concrete structure, erosion, and cavitation, among other effects, rapidly damaging the concrete of the foundation.
