On the compatibility measure in the repair systems

摘要

Bonded overlays constitute a common and versatile method for repair. Repair of concrete structure results in formation of a two-component system, i.e. concrete overlay/concrete substrate or repair material/repaired concrete. Such system must be compatible to cooperate properly. In 1992 during the International Colloquium on Materials Science and Restoration held in Technical Academy of Esslingen the principles for repair material selection based on their compatibility were formulated (L.Czarnecki, A.Vaysburd). The research in this field has been continued in Warsaw University of Technology and suitable compatibility models described by number of inequalities have been developed. These inequalities have been incorporated into the CCS software (Computer Compatibility System) developed on Warsaw University of Technology in cooperation with National Institute of Standards and Technology in 1995. The CCS presents graphically compatibility space for the given repair system. The compatibility software (CCS) allows to classify the situation in dichotomic way: compatible or incompatible. However, there is the need for compatibility (continues) measure. In this paper a relevant ratio of destruction energy concept was presented as the potential compatibility measure.
