Performance Evaluation of Different Repair Concretes Proposed for an Existing Deteriorated Jetty Structure

Abstract

Performance of different cementitious repair materials is studied as part of an ongoing repair project on an existing reinforced concrete jetty in harsh environment of Persian Gulf. Concrete repair materials with different cementitious binders including ordinary portland cement, silica fume, and ground granulated blast furnace slag were tested. Different performance criteria such as mechanical properties, durability characteristics, and dimensional compatibility with substrate concrete were studied according to a proposed rational approach. It is concluded that a repair technique containing ternary pozzolanic materials has the best performance and could be proposed for marine environment.
