According to historical records, the dam was first built in the 19th century to power a water mill. In this article, the main attention focused on the main physical-mechanic properties of concrete samples taken from Bražuolė dam – first officially removed dam in Lithuania (in 2020). The purpose of these investigations based on field research is to establish actual quantities of compression strength, density, and water absorption by weight of concrete used in the retaining walls of Bražuolė dam. The concrete water absorption by mass (Wm) and compression strength (fck) testing results based on research data of concrete samples from Bražuolė hydroscheme retaining walls do not meet the requirements of currently valid technical construction regulation.
