Polymer Composites for Repairing of Portland Cement Concrete: Compatibility211 Project

摘要

The impetus for this project has been the continuing deterioration of, and the211u001enecessity to repair, a large stock of concrete structures. A two-component 211u001esystem, portland cement concrete (substrate) in contact with a polymer composite 211u001e(repair), is produced as the result of a repair. The reliability and durability 211u001eof a repaired concrete structure and its remaining service life depends, to a 211u001egreat degree, on the behavior of the repair material, which is controlled by the 211u001ecompatibility between the two materials making up the repair system. The main 211u001escientific objective of this project has been the analysis and prediction of this 211u001ecompatibility using the compatibility space concept, which is defined 211u001emathematically, with the aim of understanding the nature of the two-component 211u001erepair system. The engineering objective has been to develop a useful 211u001ecomputational tool for predictions of the behavior and effectiveness of polymer 211u001ecomposite-portland cement concrete systems so as to select the proper 211u001erepair/protective materials for a specific application. The compatibility space 211u001ecan also be analyzed to help predict the properties that will be needed by new 211u001ematerials.
