    The present paper gives an overview of the research onHigh Performance Fiber Reinforced Cementitious Composite -- HPFRCC --pipes recently carried out at Department of Structural Engineering, Technical University of Denmark. The project combines material development, processing technique development as well as structural design. Material development was carried out considering both processing requirements as well as mechanical properties of the hardened material. A micro-mechanical model for the non-linear material behavior of the hardened material based on the stress-crack width or the $\sigma-w$ relationship is presented. Structural development involved definition of a new type of semi-flexiblecement based pipe, i.e. a cement based pipe characterized by the fact that the soil-pipe interaction related to pipe deformation is an importantcontribution to the in-situ load carrying capacity of the pipe itself. The structural modeling of the pipe was done making direct use of the $\sigma-w$ material characterization. The processing technique developed is a novel type of extrusion combiningease of material mixing and few requirements for material pre-processingwith a high degree of accuracy and stability of the newly extruded material.
