摘要：
Diffusion of chloride ion through 7.5 cm × 15.0 cm concrete cylinders was studied.The cylinders were immersed for 30 days in a tank containing distilled water and a sodium chloride solution. Five water/cement (w/c) ratios and three curing times (tc) were tested. It is suggested that coarse aggregate is a barrier which blocks chloride ion diffusion. A model considering a homogenous and porous concrete was used to describe the influence of high w/c ratios and tc. A dependence between tC and the chloride concentration at the concrete surface (C0) for high w/c ratios was found. Dispersion in the results was minimized by using a large number of specimens.
