Compressive Properties of Steel Fiber Reinforced Ultra High Strength Concrete

Abstract:

The compression tests were carried out to investigate the compression behavior of steel fiber reinforced ultra high strength concrete(SFRUHSC). Cubic and axial compression specimens were tested at room tempreture, in terms of load control. The result shouwed that the compression strength of 150×150×150mm³and 100×100×100mm³ cubic specimens is 108.4MPa and 94.7MPa, while the 100×100×300mm³ axial specimens’ is 73.4MPa. The above data demonstrated that the different size effect from that of strength of steel fiber reinforced concrete(SFRC), namely the strength of 100×100×100mm is larger than that of 150×150×150mm³. Two kinds of compression specimens showed various fracture mode: ductile tension fracture of cubic specimens and the brittle shearing fracture of axial ones. But the steel fibers inside the specimens had been pulled out from the matrix.
