FRACTURE AND ADHESION PROPERTIES OF A CARBON FIBER-CEMENTITIOUS COMPOSITE WITH SILICA FUME VARIABILITY IN THE MATRIX

A carbon fiber cement composite (CFCC) has been developed to be used for overlay on old concrete. Three aspects of CFCC mechanics, with varying silica fume (SF) dosages, have been investigated through an experimental program: amount of fracture energy of CFCC; adhesion between the fiber and the matrix; adhesion between the CFCC and old concrete. Five different matrices have been considered. Some new types of tests for the aspects investigated are discussed. The results of this work estsablish that the incorporation of SF seems to be beneficial for the toughness of the composite, while not beneficial for the adhesion between composite and old concrete.
