Which repair material should be chosen and how to use it are questions that have arosen because of earlier unsuccessful concrete repairs. Several investigations [l-31 stress that the compatibility between the repair material and the old concrete is important, in order to achieve a successhl concrete repair. The lifetime of a concrete construction can be optimised if the repair is done in the right moment and with a correct technique. Costs and natural resources can also be saved with optimal repairs. With thorough investigations and studies of the transition zone between repair material and old concrete and studies of different repair materials understanding for mechanisms and parameters that affect the lifetime of the repair can be achieved. This investigation is a pilot study to the PhD project 'Characteristics of the repair material and the transititon zone between repair material and old concrete'. The objective of this pilot study is to collect existing knowledge and experience by interviewing people working in the area of concrete repairs at SNRA, Swedish National Road Administration, and SNRaA, Swedish National Rail Administration. In order to achive a more complete picture of the repair strategies currently used in Sweden interviews with material producers, contractors and repair consultants were also carried out. The conclusions from these interviews and suggestions for areas that need hrther investigation and research are presented in this paper. The interviews were complemented by a literature review. The whole pilot-study is presented in 'CBI-commision report 2004-56', , and was financed by SNRA, SNRaA and CBI.
