Construction of double-curvature, thin-arch dams prompted an acute interest in the tensile strength, both static and dynamic, of concrete. The influence on tensile strength of such variables as specimen size and shape, aggregate size and shape, cement content, and water-reducing admixtures was questioned. This report considers only static tensile strength. Many indirect methods, whereby tensile strength is derived rather than measured, were studied and it was apparent that the - splitting test - was the best substitute for the direct method. Constituents used for this study included aggregates from three sources graded to 19-, 37.5-, 75-, and 100-mm (3/4-, 1 1/2-, 3-, 4-in) maximum size, two cements, one fly ash, and one WRA. Two specimen sizes and configurations were used.
