Abstract:Presents results of an investigation carried out to determine the effect of specimen size on tensile strength of concrete using direct-tension, ring-tension, and splitting-tension tests. A total of 21 concrete mixes were prepared and 6 and 12 in. (15 and 30 cm) diameter rings and 4 x 8-in. (10 x 20 cm) and 6 x 12-in. (15 x 30 cm) cylinders were cast and tested. The analysis of results showed that irrespective of the test method used, tensile strength values decreased with increase in the size of specimens. The average decrease in strength varied from about 14 percent in the ring-tension test to about 7 percent in the direct-tension and splitting-tension tests.
