Abstract:

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 white masonry concrete WMC. Forty-four mechanical property tests consisting of two hydrostatic compression tests, four unconfined compression UC tests, 17 triaxial compression TXC tests, two uniaxial strain tests, four uniaxial strain loadbiaxial unload UXBX tests, five uniaxial strain loadconstant volume tests, two uniaxial strain loadconstant strain ratio tests, five direct pull DP tests, and three reduced triaxial extension RTE tests were successfully completed. In addition to the mechanical property tests, nondestructive pulse-velocity measurements were performed on each specimen. The TXC tests exhibited a continuous increase in principal stress difference with increasing confining stress. A recommended compression failure surface was developed from the TXC and UC test results. Test data from the RTE and DP tests were used to develop a recommended extension failure surface for WMC. Results from the stress paths of the strain path tests and the recommended compression failure surface exhibited good agreement except for the UXBX tests.
