Interface Properties in Extruded FRC-Materials

    Research output: Chapter in Book/Report/Conference proceedingArticle in proceedingsResearchpeer-review


    In a research and development project recently carried out at Department of Structural Engineering and Materials, Technical University of Denmark a new extrusion process for HPFRCC-materials was demonstrated.It is shown that superior interfacial properties are obtained in a polypropylene fiber reinforced cementitious material extruded by the developed process. It is further more shown that the fiber-matrix bond is highly dependent on the relative slip at the interface and a bond-slip relationship is suggested for the extruded material. The observed very high fiber-matrix bond is explained by the densification of the interfacial matrix material which has taken place during the consolidation process and which can be observed in the thin-section analysis.
