The subject of the paper is a battery of silos for rapeseed located in Oil Factory in Bodaczów. It consists of 24 cylindrical silos with capacity of 500 tons and 14 star-shaped chambers between them with a capacity of 100 tons each. The silos were supported on the supporting structure in the form of permeating ring beams and columns. The height of a single silo is 25 m, and the diameter about 6.0 m. Detailed macroscopic tests were performed on the battery of silos. Destructive and sclerometric in-situ quality tests and pull-off test were performed on the concrete, the degree of concrete carbonation was estimated. The position of the reinforcement in the concrete structure and the corrosion of the reinforcement steel were determined. Static and strength calculations were carried out. Based on the results the technical condition of the object was estimated as poor, locally due to the significant loss of concrete and structural reinforcement it was estimated as imminent failure. The article presents the results of these tests, describes the reasons for the poor technical condition of the structure and presents solutions to restore its functional efficiency. A comprehensive repair of the battery of silos is currently underway applying the proposed solutions.
