Abstract:
Repair of a concrete structure results in formation of a two-component system i.e. repaired concrete/repair material. Such systems must be compatible to co-operate properly. A number of inequalities have been developed based on the compatibility definition thus creating a model of good co-operation between the combined materials. Relevant areas of good compatibility of the repair materials with ordinary concrete were based on the model. Taking into account the technical features of commercially available repair mortars (polymer and cement-polymer ones) relevant systems were then qualified as compatible or incompatible. The good compatibility model has been experiementally verified through application of the RILEM method. In all cases the compatibility status assessments determined by way of calculation or and laboratory were consistent. Based on the experimental tests and analytical calculations proper conclusions concerning further studies to be pursued on concrete repair material selection were formuled.
