Repair Material Compatibility Requirements for Long Term Concrete Repairs
Project ID: 385
Principal Investigator: Kurt Von Fay
Research Topic: Repair and Maintenance
Funded Fiscal Years:
2014
Keywords: concrete repair, material compatibility, long lasting repair
Project Abstract
Many conventional concrete repair materials typically crack and/or debond after only a short period of time (a few months to a few years), setting the stage for premature repair failure by allowing ingress of water, air, chlorides and other contaminants into the concrete. These contaminants can lead to further deterioration of the concrete and corrosion of steel reinforcement. Industry wide conventional repairs are estimated to last only on the order of 5 to 7 years.
Reclamation's Science and Technology program provided funding for a scoping study on material compatibility issues of concrete repair materials with existing concrete. The goal of this paper is to present the basis for the development of relevant design rules and technical guidelines for the achievement of durable concrete repairs and overlays and to identify areas where additional studies regarding material compatibility issues are warranted
