SONISCOPE APPLIED TO MAINTENANCE OF CONCRETE STRUCTURES

THE SONISCOPE IS AN ELECTRONIC DEVICE FOR THE NONDESTRUCTIVE TESTING OF MATERIALS. THE INSTRUMENT MEASURES THE TIME DELAY OF A SHOCK WAVE SENT THROUGH THE MATERIAL, FROM WHICH THE VELOCITY OF PROPAGATION OF SOUND WAVES CAN BE COMPUTED. THIS VELOCITY REPRESENTS A MEASURE OF THE QUALITY OF THE MATERIAL. TESTING TECHNIQUES FOR VARIOUS TYPES OF STRUCTURES ARE DISCUSSED. TESTS ON PRESTRESSED-CONCRETE BEAMS LOADED TO FAILURE SHOW A CLOSE CORRELATION OF SONISCOPE READINGS WITH THE BEHAVIOR OF THE BEAM. THE INFLUENCE OF REINFORCING STEEL IS SHOWN BY TESTS ON A REINFORCED BRIDGE PIER. THE DETECTION OF CRACKS AND DETERIORATION IN CONCRETE ARE BOTH DEMONSTRATED BY TESTS OF SEVERAL BRIDGE MEMBERS. A GRAPHICAL PRESENTATION OF SONISCOPE RESULTS ON A BRIDGE PIER IS THEN DISCUSSED. THE RESULTS OF THESE TESTS INDICATE THAT THE SONISCOPE CAN BE A VALUABLE SUPPLEMENT TO VISUAL INSPECTION. /AUTHOR/
