RING TEST FOR TENSILE STRENGTH OF CONCRETE

THE RING TEST APPEARS TO BE A SATISFACTORY MEANS FOR DETERMINING THE TENSILE STRENGTH OF CONCRETE. THE SPECIMEN AND THE TESTING APPARATUS ARE SO SIMPLE THAT BOTH FABRICATION AND TESTING CAN BE CARRIED OUT RAPIDLY EVEN AT A CONSTRUCTION SITE. IN SPITE OF THE SIMPLICITY OF THE EQUIPMENT, A HIGH DEGREE OF REPRODUCIBILITY IS ACHIEVED IN THE TEST RESULTS. THE METHOD OF APPLYING HYDROSTATIC PRESSURE IS SUCH THAT THE APPLIED PRESSURE IS ALWAYS PERPENDICULAR TO AND UNIFORM OVER THE ENTIRE INSIDE RING PERIPHERY. THUS THE RING TEST DOES PROVIDE APPROXIMATELY TRUE TENSILE STRESS AS IS OBTAINED IN THE CLASSIC AXIAL TENSION TEST, BUT DOES NOT HAVE THE DISADVANTAGES ASSOCIATED WITH THE LATTER TEST. THE GEOMETRY OF THE TEST SPECIMEN USED AND THE NATURE OF THE APPLIED PRESSURE ARE SUCH THAT THE WHOLE INTERNAL PERIPHERY OF A CONCRETE RING IS SUBJECTED TO A UNIFORMLY DISTRIBUTED MAXIMUM STRESS. THUS THE STRENGTH OBTAINED BY THIS TEST METHOD MORE CLOSELY APPROXIMATES THE ACTUAL TENSILE STRENGTH OF CONCRETE, SINCE THE TEST IS BASED UPON THE WEAKEST LINK THEORY. /AUTHOR/
