Abstract:
One hundred seventy 100-mm cubes for biaxial compression specimens and 40 cubes for triaxial compression specimens were tested. The tests were taken in a special device containing a pressure chamber to exert lateral loading and an ordinary material-testing machine to exert vertical loading. This device can exert random ratios of triaxial and biaxial compression loading. Two 2-mm fluorine-based resin sheets with molybdenum sulfide grease were used as a friction-reducing pad. Test results of biaxial and triaxial compressive concrete strength are suggested. Failure modes of the concrete specimens under biaxial and triaxial compression are also described.
