The impetus for this project has been the continuing
deterioration of, and the necessity to repair, a large
stock of concrete structures. A two-component system,
portland cement concrete (substrate) in contact with a
polymer composite (repair), is produced as the result of
a repair. The reliability and durability of a repaired
concrete structure and its remaining service life
depends, to a great degree, on the behavior of the
repair material, which is controlled by the
compatibility between the two materials making up the
repair system. The main scientific objective of this
project has been the analysis and prediction of this
compatibility using the compatibility space concept,
which is defined mathematically, with the aim of
understanding the nature of the two-component repair
system. The engineering objective has been to develop a
useful computational tool for predictions of the
behavior and effectiveness of polymer composite-portland
cement concrete systems so as to select the proper
repair/protective materials for a specific application.
The compatibility space can also be analyzed to help
predict the properties that will be needed by new
materials. Results of the project are presented in this
report, and in the Compatibility Computer System (CCS),
whose User's Manual has been published as an appendix to
this report. A second appendix contains a list of the
17 publications that were presented at international
forums in English and Polish and published in
proceedings and journals during the project. The
project's results are in general accord with worldwide
scientific and engineering activities in repair
materials. e.g., U.S. Research Program on Repair,
Evaluation, Maintenance and Rehabilitation (ReMR),
European Standard Activity on products and system for
the protection and repair of concrete structures (ENV
1504 - pending) as well as the periodic meetings of the
International Colloquium on Materials Science and
