The effect of the rate of application of load on the compressive, tensile-splitting, and flexural strengths of specimens from three concrete mixtures having static compressive strengths of approximately 2000, 3000, and 4000 psi, respectively, was investigated. The test specimens were cast as 1-12- by 3-in. cylinders, 3- by 6-in. cylinders, and 6- by 6- by 20-in. beams, which were tested in compression, tensile splitting, and flexure, respectively. Dynamic loading of the specimens was accomplished with the rapid-loading MIT- WES gas-operated impact machine. Resistance-wire strain tensile-splitting tests to obtain stress-strain relations. Static tests were made on a hydraulic testing machine.
