Chloride profiling in concrete harbour structures – a study of extensive variations

The aim of this work is to try to explain why the chloride profiles differ even though the samples are taken in a homogeneous concrete, and within a small area.

Slabs were submerged in a 13.5 % NaCl solution for about six months. Two different sampl
