Abstract

Ductility is one of the main requirements of a reliable building material; the traditional LOP and MOR criteria do not reveal this quality. Other criteria based on deflection, energy or bond-slip relationships are presented. They are applied to four very different series of composites: very brittle, very ductile, and intermediate. The results point out that only the criteria based on the flexural test up to splitting, at a constant deflection rate, can reveal the higher ductility of the metakaoline-OPC blended matrix associated with AR glass. From this test, the bond-slip relationship can be determined. This leads to the definition of a comparative parameter which describes the mechanical interfacial compatibility of the matrix versus the fibers.
