摘要
The effects of steel micro-fibre on the complete load-displacement response of a high performance concrete in tension and compression were examined from tests performed on specimens composed of high strength concrete under controlled strain through a closed-loop system. The concrete had a maximum aggregate size of 3 mm, an aggregate to binder ratio of two, silica fume to binder ratio of 0.2, water to binder ratio of 0.225 and randomly dispersed steel micro-fibres of 0%, 2%, 4% and 6% by volume. Uniaxial tensile tests, bending tests and uniaxial compressional tests were conducted and analyzed in order to provide a mechanical characterization of the materials. Moduli of elasticity and fracture energies were evaluated and compared. (C) 1997 Elsevier Science Ltd.
