Abstract: The investigation consisted of the evaluation of a ring tensile test method for determining a measure of the tensile strength of mortars and concretes. The evaluation was based on the reproducibility and degree of simplicity of the test method, Correlations were made between the ring tensile strength and the cylinder compressive strength and tensile strength values obtained from beam flexural and cylinder splitting tests of sanded mortar, 3/8-in. maximum size aggregate concrete, and 1-in. maximum size aggregate concrete, all made at water-cement ratios (by weight) varying from 0.4 to 0.9. Two sizes of test rings were evaluated: 1.5 in. high by 1.5 in. thick by 6 in. inside diameter and 3 in. high by 3 in. thick by 12 in. inside diameter. The mortar tests used 6-in. rings, the 3/8-in. concrete used both 6- and 12-in. rings, and the 1-in. concrete used only 12-in. rings. total of ninety-two 6-in. rings and eighty-three 12-in. rings were tested.
