MECHANISM OF THE ADHESION OF ORGANIC BINDERS TO CONCRETE

MECANISME D'ADHESION DES LIANTS ORGANIQUES AU BETON

TO STUDY THE ADHESION MECHANISMS OF THE ORGANIC BINDERS USED IN THE REPAIR OF STRUCTURES. THE FIRST ASPECT INVESTIGATED WILL BE THE PROBLEM OF INJECTION IN NARROW CRACKS. WITH THIS AIM IN VIEW, THE INTERFACIAL PARAMETERS (WETTING ANGLES, ADHESION TENSION) OR THE PARAMETERS SPECIFIC TO THE BINDER (CHEMICAL FORMULA, PHYSICAL CHARACTERISTICS) INFLUENCING THE INJECTION PROCESS IN A TYPICAL CRACK WILL BE DEFINED AND STUDIED. AN ATTEMPT WILL BE MADE TO ESTABLISH POSSIBLE RELATIONS BETWEEN THOSE PARAMETERS AND THE MECHANICAL BEHAVIOUR OF THE REPAIRED STRUCTURE.
