Abstract: The phenomenon creep fracture is well-known for concrete. Since 1960 it is known that delayed fracture may occur for concrete structures at sustained loads beyond roughly 80% of the short term peak resistance in compression and flexure. More recently, evidence has been produced of an even lower creep fracture limit exists for concrete, potentially as low as 60% of the peak short term resistance in flexure. Such characterisation and consideration of creep and creep fracture are essential for design guidelines for HPFRC and form the focus of this paper. A comprehensive experimental program has been launched to characterise the time dependent behaviour of a particular HPFRC, including creep and creep fracture, as well as shrinkage. In this paper, results are presented of direct tensile tests, as well as three point bending tests towards establishing the creep and creep fracture behaviour of a particular HPFRC.
