Abstract: Increase in ductility of cementitious composites is the most promising improvement as construction materials. Such improvement widely extends the application of cementitious composites for structural components of high performance especially in case of strong earthquakes. In order to improve further the ductility, hybrid fiber reinforced cementitious composites in which different types of fibers are mixed together to share the different roles are developed. In the present study, twisted steel fiber and polyethylene fiber are used. Tensile behavior is investigated by means of uni-axial tension tests eliminating completely the secondary flexure effects. It is proved that the combination of twisted steel fiber and polyethylene fiber is very effective to improve the ductility by increasing absorbed energy as well as achieving strain hardening in the stress-strain relationship.
