The Repairing of Concrete Walls in Structure for Water Treatment in Thermo Power Plant

Abstract

As a result of longer term exploitation, exposure to severe weather conditions or influence of chemical conditions, concrete walls of concrete structures get damaged internally as well as externally. This study includes a preliminary analysis of chemically treated water in existing concrete structures, and another after the application of the method and using materials for the structures in future. One of the priorities was to examine the existing concrete structures by using nondestructive and destructive methods. After that, based on the results of the analysis, adequate new materials are proposed for the repairs, most commonly new technology polymer carbonated materials, in order to achieve durability of structure elements in using technological processes. Behavior of the repairing structures was tested using the in situ methods, and especially pull-of test, to verify the adhesion force between the old concrete structures and new applied layer. After the repairing, the concrete structures will be monitored to record the behavior under the chemical treated water.
