Quality Control of the Concrete of the Supporting Structure of Bridge Reg. No. 333-003 over the Elbe in Přelouč

Abstract:

This paper is introducing results of diagnostic survey of bridge reg. No. 333-003 over the Elbe in Přelouč [1], which included an evaluation of the previous reconstruction carried out in the 1990s [2, 3] and the quality control of the concrete used in the construction after more than 90 years of operation. Visual inspection, comparison of depth of concrete carbonation and thickness of top layer of reinforcement concrete and concrete compression strength are presented in this paper. This paper come into existence with cooperation with the state-funded organization Road Administration and Maintenance of the Pardubice Region.
