ABSTRACT
For a durable concrete repair in case of external chloride or sulphate ingress it is necessary to remove the contaminated concrete. A depth profile gained with LIBS laboratory equipment in a mm scale helps the engineer in the planning process to decide the depth of the concrete removal. A portable LIBS equipment for on-site use will help to make a quick decision whether concrete removal is sufficient or not. Only access to the prepared surface that should be tested is necessary.
