Abstract
The effect of the geometry of polypropylene fibres and their surface treatment by chemical and physical means was studied to obtain cementitious composites with optimal flexural properties. Monofilaments of polypropylene were more efficient than split film or bundled multifilament strands. Acid, detergent and rubbing treatment of monofilaments were found to be particularly effective in enhancing the first crack stress and post-cracking behaviour of the composite. The influence of the various treatments was discussed in terms of the bonding nature as deduced by scanning electron microscope observations of the fibre-matrix interface.
