INVESTIGATION OF THE BEHAVIOR OF CONCRETE UNDER TENSILE STRAIN GRADIENTS

THE RESULTS OF AN INVESTIGATION INTO THE RELATIONSHIP BETWEEN SEVERAL STANDARD TESTS ON CONCRETE ARE REPORTED. SPECIFICALLY, THE MODULUS OF RUPTURE TEST, THE SPLIT CYLINDER TEST AND THE CYLINDER COMPRESSION TEST ARE COMPARED WITH A DIRECT TENSION TEST OF A 3X5 INCH RECTANGULAR SPECIMEN SUBJECTED TO A TENSILE STRAIN GRADIENT. THE PRIMARY EXPERIMENT INVOLVED MORTAR SPECIMENS, ALTHOUGH CONCRETES CONTAINING LIMESTONE AND SOLITE, A LIGHTWEIGHT AGGREGATE, WERE ALSO INVESTIGATED. SOME CONCLUSIONS RESULTING FROM THE COMPARISONS WERE: /1/ THE TANGENT MODULUS OF ELASTICITY OF CONCRETE IN COMPRESSION IS APPROXIMATELY EQUAL TO THAT IN TENSION, /2/ THE MODULUS OF RUPTURE TEST DOES NOT GIVE A GOOD INDICATION OF THE TENSILE STRENGTH OF CONCRETE, AND THE /3/ INTRODUCTION OF COARSE AGGREGATE INTO THE MORTAR PRODUCES A STRESS-STRAIN CURVE THAT IS MORE LINEAR THAN THAT FOR MORTAR. /BPR/
