Abstract: This article presents field observations and results from experimental studies on the moisture conditions and frost resistance of concrete in Swedish hydroelectric structures. The experimental work has been carried out by subjecting concrete specimens to exposure
conditions similar to those at existing structures. It was shown that surface deterioration at the waterline is caused by interactions between leaching, frost action and abrasion. Moreover, macroscopic ice lens growth can occur in hardened concrete under certain conditions. Measurements and microstructural analyses were conducted on concrete samples from existing hydroelectric structures to verify the results from the laboratory-cast concrete.
