MEANS OF REPAIRING CONSTRUCTIONAL DEFECTS IN CONCRETE STRUCTURES

MOYENS DE REPARATION DES DEFAUTS D'EXECUTION DES OUVRAGES EN BETON

TO DEFINE METHODS OF REPAIRING THE DIFFERENT TYPES OF DEFECT ENCOUNTERED AND, IN PARTICULAR, TO STUDY THE RESUMPTION OF CONCRETING. OBSERVATIONS WERE MADE IN 1975 ON SMOOTHING OPERATION, INJECTION OF CRACKS AND USE OF SHOTCRETE. IN 1976, THE WORK WILL CONSIST OF: THE STUDY OF THE INJECTION OF CRACKS BY MEANS OF CHROMATOGRAPHY AND RESTORATION OF ONE STRUCTURAL ELEMENT; THE FOLLOW-UP STUDY OF THE REPAIR OF CRACKED STRUCTURES; THE INVESTIGATION INTO RESUMPTION OF CONCRETING; THE ANALYSIS OF REPAIR PRODUCTS AND USE OF FIBRES. PROCEDURES WILL BE DRAFTED TOGETHER WITH A GUIDE ON REPAIR METHODS.
