Abstract: A great diversity of different cement based fibre reinforced (FRC) materials can be found today either in practical use or under development in research laboratories. These include materials with significantly different material properties as well as materials with very different constituents and structure. At the same time a need for design guidelines for the use of FRC-materials has been widely recognized both by researchers and practical engineers. Design guidelines based on a simple material classification as well as representation of (mechanical) material properties can be considered as a pre-requisite for further advancement of application of innovative FRC materials and for focusing of the research in such materials.
The paper discusses and presents a fundamental classification based on the concepts of (pseudo) strain hardening and tension softening. The paper further sheds light on this classification by describing existing and possible structural applications based on the utilization of the material characteristics in serviceability and ultimate limit state. The classification is further substantiated, by presenting simple engineering representations of the mechanical behaviour in the two cases, suitable for structural design. The representation of mechanical properties is related to test methods and the availability of and requirements to standardized methods is discussed. Durability performance is discussed and the required durability performance testing for each class of material is described along with envisioned results. Finally, the implementation of results from durability in the various types of design approach is described.
