ABSTRACT
This paper describes the performance driven approach in the design of fiber reinforced cementitious composites. This approach is illustrated with structural durability as an example. The identified material property, crack width, is then related quantitatively to material structures — fiber, matrix and interface properties, by means of micromechanics. It is suggested that tailoring of material structure can lead to controlled crack widths, and hence directly influences the durability of built structures. Success in the performance driven design of fiber reinforced cementitious composites will depend on future research in quantifying links between specific structural performance, material properties, and material structures.
