Abstract
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.
