THE EFFECT OF ADMIXTURES AND PROTECTIVE PAINTS ON THE RATE OF CORROSION OF STEEL EMBEDDED IN CONCRETE
2006
Smith, C. W.
Test results indicated that (1) salt water alone and interactions between salt water and plastiment and CaCl2 respectively, produced the greatest amounts of corrosion. The corrosion rate caused by salt water is 1.55 times that exhibited by fresh water mixes, a salt water with plastiment mix causes 5. 14 times the corrosion rate caused by fresh water mix with no plastiment, and a salt water mix with calcium chloride causes 17.6 times the corrosion rate exhibited by a fresh water mix with no calcium chloride, (2) in general, no significant reduction in corrosion rates is achieved through the use of the concrete coating employed except when CaCl2 is used, and (3) for protection against the corrosion for salt water mixes, the steel coating employed produced remarkable results, in some cases reducing corrosion by 600%. In fresh water, however, the beneficial effect of the steel coating was only slight.
