摘要

Ternary mixtures of concrete with Portland, fly ash and finely ground granulated slag were producedto investigate their effects on the compressive strength and corrosion resistance. Portland cement waspartially replaced by alternative materials with water / cement ratio (w / c) of 0.50. The mechanicalstrength it was evaluated by compression tests and the corrosion resistance using Half-cell potentials.The results indicate that fly ash and blast furnace slag, greatly reduce the chloride permeability ofconcrete and increases the corrosion resistance both short- and long- time evaluation. Therefore it isconcluded that to control the corrosion resistance in the presence of chloride ion, including pozzolan isan effective method.
