Abstract—This study was performed to evaluate chloride ion penetration depths in concrete produced with high early strength Portland cement with and without silica fume replacement (10% by mass). Two curing procedures were used to produce precast structures curing: air and steam curing at 60 ºC. Chloride ion depths were measured at 90 days by spraying a solution of 0.1N AgNO3 at specimen surfaces. The results showed that Chloride ion penetration depth in silica fume concrete was diminished.
