Abstract

Macro polyolefin fibres can effectively improve flexural toughness and post-cracking performance of concrete, they are hence becoming popular in various constructions. This research focused on quantifying reinforcing effects of macro polyolefin fibres in concrete using round determinate panel test. Effects of fibre length, fibre dosage and concrete strength on the toughness of fibre reinforced concrete were investigated. A new characterisation method using toughness index was preliminarily attempted to introduce. It reflects the degree to which the fibre changes the toughness of plain concrete. It also "normalises" the toughness into approximately the same magnitude with other flexural tests, making it possible to compare with different flexural tests.
