CONCRETE REPAIR TECHNOLOGY: A REVISED APPROACH IS NEEDED

Abstract

This article analyzes some common problems with concrete repairs, attempts to provide revised opinions on various concrete repair issues and explores issues that need further investigation. Most faults and problems in concrete repair can be attributed to lack of attention to condition evaluation, design objectives and details, or poor construction practices. Developing improved performance materials will not help unless the designer and the artisan are skilled at their jobs. It is suggested that improvement in rehabilitation/repair performance should be approached in two stages. First, design and worker errors should be reduced through improved education and training. In the second stage, improved performance materials should be introduced.
