Abstract	A RILEM technical committee on Internal Sulfate Attack (TC 186-ISA) was established in 1996. In the ensuing years considerable research was carried out, which helped to clarify the scientific knowledge surrounding this form of degradation. A Seminar was organised in September 2002 to bring together the leading researchers in the field to debate the state of the advances made in this area. All known active researchers in the area were invited and most were able to attend. The workshop was organised with sessions designed to address the key questions related to Delayed Ettringite Formation (DEF) and Internal Sulfate Attack. In each session one or more invited presentations and several shorter presentations were made by leading researchers to summarise experimental findings and present their views. These presentations were followed by extensive discussion, at the end of which a summary was made of the main points of agreement and of areas where questions remained open. This report gives these discussion summaries as the current consensus view on this subject.Une commission technique de la RILEM sur l'attaque interne des sulfates (TC 186-ISA) fut créée en 1996. Au cours des années qui ont suivi, d'importants travaux de recherche sont été menés en vue d'aider à clarifier la connaissance scientifique entourant cette forme de dégradation. Un séminaire fut organisé en septembre 2002 afin que les principaux experts du domaine puissent discuter ensemble et faire état de l'avancée de leurs recherches sur ce sujet. Tous les grands chercheurs spécialistes du domaine furent invités et la plupart put assister au séminaire. Celui-ci fut divisé en sessions visant à aborder les questions liées à la formation retardée de l'ettringite (DEF) et à l'attaque interne des sulfates. Chaque session comportait une ou plusieurs présentations invitées et plusieurs interventions plus courtes, faites par les experts pour résumer leurs résultats expérimentaux et exposer leurs points de vue. Ces présentations étaient suivies par de longues discussions, à la fin desquelles était fait un compterendu, résumant les principaux points d'accord et les domaines où des questions restaient en suspens. Dans ce rapport sont regroupés les résumés de ces discussions, résultats du consensus actuel sur ce thème.
