摘要：

The article presents a part of a study carried out by the AFREM "Durability - Chloride penetration in concrete" group. It deals with the extraction of "free" and total chlorides from concrete and their titration. The goal is to define test procedures that will take into account the chemical behaviour of concrete components, in particular bound chlorides in calcium chloroaluminate. The basic features of the test procedures are presented, as well as some results of round-robin tests between five laboratories.
