Abstract
The chloride ingress into concrete under water pressures of 100 kPa and 800 kPa have been
investigated by experiments. The specimens were exposed to a 10% NaCl solution and water
mixture. For the concrete having w/c = 0.35 the experimental results show the chloride diffusion
coefficient at 800 kPa (～8 atm.) is 12 times greater than at 100 kPa (～1 atm.). For w/c = 0.45
and w/c = 0.55 the chloride diffusion coefficients are 7 and 3 times greater. This means that a
change in pressure highly influences the chloride ingress into the concrete and thereby the life
length models for concrete structures.
