Abstract


The purpose of this study is to evaluate different mortar mixtures containing 5, 10 and 1 5% P/P silica fume and 5, 10, 12.5, 15 and 17.5% P/P fly ash to be used for repairing/constructing reinforced concrete structures exposed to marine environments. These were evaluated from the following standpoints: physical-chemical (capillary absorption and effective porosity); mechanical (compressive strength); electrochemical (lineal polarization, cyclic polarización and rapid chloride permeation); morphological (scanning electron microscopy). Results showed that 15 % silica fume mixture with no fly ash gave the best performance from both the physical-mechanical as well as the economic standpoint.
