Two types of reactive powder concrete( RPC) were prepared by substition of fly- ash for fine quartz sand. The effects of volume fraction of polypropylene fibres and curing conditions on the fracture properties of RPC were studied. The results showed that the good workability can be got by less water reducer and ultimate load was increased, but the fracture energy and ductility index es were decreased with the replacement of fly- ash for fine quartz sand. The study also showed that on the same conditions, the effects on the fracture energy and ductility and fracture toughness are varied with the increase of fibre.
