A STUDY OF CRACKS IN CONCRETE BY X-RADIOGRAPHY

THE RELATION BETWEEN MICROCRACKING AND COMPLETE BREAKING OF CONCRETE UNDER BIAXIAL TENSILE AND COMPRESSIVE STRESS IS STUDIED BY X-RADIOGRAPHY. AFTER LOADING TUBULAR SPECIMENS UP TO MAXIMUM STRESS, RADIOGRAPHS WERE MADE BY ROTATING THE SPECIMENS IN A COLLIMATED BEAM OF X-RAYS. IT WAS FOUND THAT COARSE AGGREGATE PARTICLES HAVE AN IMPORTANT ROLE IN THE CRACKING PROCESS. THEY APPEAR TO PROMOTE BAND CRACKING, PARTICIPATE IN CRACK ARREST AND IN SOME CASES TO ENCOURAGE THE STABLE DEVELOPMENT OF LONG CRACKS VISIBLE ON THE SURFACE. /RRL/
