EFFECT OF CARBON FIBRES ON THE MECHANICAL PROPERTIES AND CORROSION LEVELS OF REINFORCED PORTLAND CEMENT MORTARS

Fiber composites are new materials based on carbon and other fiber types with exceptional physical and chemical properties suitable to be used in technologically advanced products. This article considers the effect of carbon fibers on the mechanical properties and corrosion levels of reinforced Portland cement mortars. The authors report on a study in which compression and flexural strengths have been determined in relation to the amount of fibers added to the mix, water/binder ratio, curing time and porosity. Additionally, the corrosion level of reinforcing steel bars embedded in Portland cement mortars containing CF and silica fume (SF) were investigated and reinforcing steel corrosion rates were determined. The results demonstrate that an optimum increase in flexural strength is obtained for a CF content of 0.5% of cement weight in the mortar. However, the addition of CF increases corrosion current density in embedded steel, probably due to the drop of electrical resistivity.
