Data for: CHLORIDE MIGRATION CHARACTERISTICS AND RELIABILITY OF REINFORCED CONCRETE HIGHWAY STRUCTURES IN PENNSYLVANIA

An experimental study was conducted to assess the chloride migration resistance of concrete used for bridge superstructure and substructure projects in the state of Pennsylvania. A total of 68 concrete mixes were sampled and tested to determine the chloride migration coefficient using NT Build 492. The results show that the concrete migration coefficient varied from 0.54 x 10-12 m2/s for a concrete with 59.4% cement type I, 35% slag and 5.5% silica fume to 30.62 x 10-12 m2/s for a concrete with 100% cement type I, the average migration for all samples was 9.51 x 10-12 m2/s.
