EFFECTS OF AGGREGATES ON SHEAR RESISTANCE OF CONCRETE

LABORATORY TESTS ON THREE CONCRETES HAVING DIFFERENT AGGREGATES /CRUSHED STONE, GRAVEL, ILMENITE/ ARE REPORTED. SHEAR STRENGTHS ARE TABULATED AND DIAGRAMS ILLUSTRATE SHEAR FAILURE PATTERNS AND RELATIONS BETWEEN SHEAR STRESS AT FAILURE AND COMPRESSIVE AND TENSILE STRENGTHS. THE LIMITED TEST RESULTS CONFIRMED THAT SHEAR STRESS OF CONCRETE IS PROPORTIONAL TO THE SQUARE ROOT OF THE COMPRESSIVE STRENGTH AND THAT THIS RELATION DEPENDS ON THE TYPE OF AGGREGATE. THE INFLUENCE OF THE AGGREGATE WAS LESS PRONOUNCED IN THE RELATION BETWEEN SHEAR STRESS AND TENSILE STRENGTH. THE INDIRECT TENSILE TEST THEREFORE APPEARS TO BE BETTER THAN THE COMPRESSIVE STRENGTH TEST AS A CRITERION OF SHEAR RESISTANCE. /RRL/
