ABSTRACT

The repair of concrete surfaces has become an everyday occurrence in today’s lifestyle. Both new and old concrete structures show exhibit fatigue that minimizes the service life of the structure. Carbon nanofibres have excellent mechanical properties that may be used in concrete to make it an excellent material of tomorrow (Balaguru, 2006). The addition of the nanofibres to a concrete mixture may have the potential to enhance the general strength of the concrete and prevent crack propagation in cement composites (Nanoscience And Nanotechnology In Cementitious Materials, 2004; Makar et al, 2005). If the concrete can be reinforced by using nanofibres, theoretically the formation of cracks can be interrupted as soon as they start to initialize.
