Shape Memory Alloy, smart material has made a significant impact in various fields especially in construction. Shape memory alloy (smart metal memory alloy) is a material which when deformed, regains its original shape. The most commonly used shape memory alloy (SMA) is nickel- titanium alloy, commonly known as Nitinol. These SMA are used presently in robotics and automotive, biomedical (for orthopedic surgery) and aerospace industries. SMA wires find numerous applications in civil engineering structures. Here, one such application of SMA in concrete members, for controlling of cracks developed or developing cracks is discussed. This review talks about intelligent reinforced concrete and its applications in civil engineering. SMA can be introduced, to reduce cracks in two ways, either externally or internally. SMA wires clubbed together as cables, is reinforced in concrete by the method of post tensioning. Thus, providing an efficient, rapid and convenient approach for repair and strengthening of damaged structures. It is only a matter of time and SMA will emerge as an essential material in construction industry. Thus, this review focuses on the potential and limitations of SMA in construction.
