Description
The purpose of this study was to investigate the performance to chloride
penetration of specimens made with three base compositions (three different
supplementary cementitious materials) and water to cementitious ratios of 0.35, 0.41, or
0.47. The specimens were subjected to bulk diffusion test or full immersion. The mixes
were exposed to 0.1 M, 0.6 M, or 2.8 M sodium chloride solution for different periods of
time. Also, partially immersed specimens were exposed to indoor and outdoor exposures
(tidal, splash, barge). Chloride concentration profiles were obtained and the apparent
diffusion coefficient was calculated. The skin effect was found only on some chloride
profiles exposed to 0.1 M sodium chloride solution. The chloride binding capacity was
calculated; specimens with 20% Fly Ash and 8% Silica Fume had the highest binding
capacity (70.99%). The apparent diffusivity coefficient was found to be dependent on the
curing regime as well as the water to cement ratio. The correlation between effective
resistivity and apparent diffusion coefficient was determined.
