The NTIS website and supporting ordering systems are undergoing a major upgrade from 8PM on September 25th through approximately October 6. During that time, much of the functionality, including subscription and product ordering, shipping, etc., will not be available. You may call NTIS at 1-800-553-6847 or (703) 605-6000 to place an order but you should expect delayed shipment. Please do NOT include credit card numbers in any email you might send NTIS.

Title Development of a Failure Theory for Concrete. Summary.
Publication Date Aug 2012
Media Count 1p
Personal Author M. Roddenberry R. Kampmann W. C. V. Ping
Abstract Concrete has been in use for over 2,000 years, yet the behavior of this common, but complex, substance is not fully understood. This gap affects standard compressive strength testing (ASTM C 39), which does not account for structural effects caused by sample geometry, size of contact surface, and intensity of surface friction at the compression interface. To assess the true compressive strength of concrete and to study the natural crack propagation within concrete materials, the conventional test method must be modified to reduce or eliminate structural effects. In this project, the Florida Department of Transportation contracted researchers from Florida A&M University/Florida State University College of Engineering to investigate failure mechanisms in concrete under compression and to determine how accurately standard compressive testing assesses concrete strength.
