Abstract: 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', [4], and was financed by SNRA,
SNRaA and CBI.
