Overall structural behavior of high strength concrete specimens

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 0/100, 2/100. 4/100 and 6/100 by volume.
