Abstract
Shape memory alloy is a smart material whose usage in reinforced concrete members has been increasingly raised in recent years. This paper focuses on applications of different shapes of the shape memory alloy as an internal, external, and near-surface strengthening element of reinforced concrete members. Initially, the application of the alloy in the civil engineering field, in general, is briefly reviewed. Then, the types and characteristics of the alloy are discussed. Application of the alloy in different formats as a strengthening element for new and old concrete structural systems is presented. The paper reviews some applications of the alloy in concrete, which may demonstrate available gaps that can be filled in by further investigations.
