Abstract

When designing reinforced concrete structures in environments where a high content of salts is present, special measures must be taken to ensure its durability.

In this paper, three different situations are analysed: marine environment characteristic of areas all around the world within a strip of about 5 miles from the nearest sea coast; semi-desertic environment occuring in some widespread areas, mainly around the North of Africa and the Middle East; reinforced concrete structures subject to high deicing salts characteristic of the North of Europe and America.

The effects of chlorides both in concrete and reinforcement are described and the singularities of each environment are outlined.

The design of structures in such aggressive surroundings starts, from the very beginning, on the choice of materials and its storage at the site of the construction. The detailing of the reinforcement and the measures to be taken in the design are also described.

It is concluded that these environments present no deadly problems as far as durability is concerned if their characteristics are taken into account from the beginning of the whole process of designing and building a structure.
