✦ Synopsis

The Central Laboratory for Bridges and Roads of the French Ministry of Equipment published in 1 991 the 'Provisional recommendations for the prevention of damage by the alkali-aggregate reaction'. This document is the production of a technical committee, the members of which belong to representative French civil engineering organizations.

The paper presents the context in which these recommendations have been written and details the preventive approach which consists of two stages. At the first stage, it is recommended to fix the level of prevention to be attained among three possible levels, the choice depending on both the category of the structure and its exposure class. At the second stage, the recommendations concern possible solution(s). Thereafter the paper presents the five possible ways offered in the general case. To minimize the risk, it is sufficient for one of the five conditions detailed in the text be verified.
