dc.descriptionAbstract: Personnel of the Geotechnical and Structures Laboratory, U.S. Army Engineer Research and Development Center, conducted a laboratory investigation to characterize the strength and constitutive property behavior of a gray masonry concrete. A total of 38 mechanical property tests were successfully completed: two hydrostatic compression tests, four unconfined compression (UC) tests, 16 triaxial compression (TXC) tests, two uniaxial strain tests, two uniaxial strain load/biaxial strain unload tests, five uniaxial strain load constant volume strain loading (UX/CV) tests, two uniaxial strain load constant strain ratio (UX/SR) tests, three direct pull tests, and two reduced triaxial extension tests. In addition to the mechanical property tests, nondestructive pulse-velocity measurements were performed on each specimen. The TXC tests exhibited a continuous increase in maximum principal stress difference with increasing confining stress. A compression failure surface, as developed from the TXC test results at eight levels of confining stress and from the results of the UC tests. The results of the direct pull and reduced triaxial extension tests were used to develop the extension failure surface. The resulting compression and extension failure surfaces were well defined and nonsymmetric about the mean normal stress axis. Good correlations were observed between the stress paths obtained from the UX/CV and UX/SR strain path tests and the failure surface from the TXC test.-
