Summary on Grant Application Form |
|
Surface treatments (eg coatings) are increasingly being applied to concrete structures to provide a partial barrier against aggressive agents that may lead to premature deterioration. There is currently no in situ test method that can separate the protective effect of the surface treatment from that of the underlying concrete, rendering performance-based surface treatment assessment, compliance testing and long-term monitoring impractical. A spin off from a recently completed LINK project was the finding that ac impedance spectroscopy may well form the basis of such a technique. The primary objective of this project is to develop an impedance based method for characterising surface treatments in situ on concrete structures.In Phase 1, test cells will be developed, alternative test cell geometries will be investigated and methods of preconditioning the surface treatment will be explored. In Phase 2, the test method will be applied to identify the influence of important operational, environmental and surface treatment variables on the test results. In Phase 3, surface treated reinforced concrete panels will be exposed and tested on site. Recommendations will then be developed regarding the use of the test for surface treatment assessment, compliance testing and long-term monitoring.
