a study on compatibility of concrete repair materials

A Study on Compatibility of Concrete Repair Materials

repair material should be compatible with existing concrete substrate. It is widespread acceptance that the compatible repair material will withstand the adverse environmental condition over a design period. Good bond strength between overlay and substrate is a key factor in the performance of concrete repair materials.

Feb 01, 2001  For the repair materials used in this study and stored under a hot-dry environment, the conclusions can be summarised as follows: 1. High shrinkage strains of the cementitious repair mortars affected their compatibility with concrete, and increased indirectly the permeability at the interface of the combined system by one order of magnitude. 2.
