Local distressing of concrete structures is often observed in the form of concrete cracking and spalling. If the damage is severe it could even lead to the corrosion of reinforcing steel. Concrete distressing is often attributed to factors like aging, freeze-thaw cycles, and the presence of harsh chemicals. Compensating the lost capacity of distressed members through local prestressing of damaged regions could be a quick and easy fix for such problem. However, the application of conventional prestressing techniques using steel strands in small and local areas could be complex or non-feasible. In this work an innovative and simple prestressing technique using thermally prestressed cementitious laminates is investigated. The laminates could be fastened on the surface of the damaged regions then thermally prestressed using internally embedded Shape Memory Alloy (SMA) wires. SMA is a unique metallic alloy which could be prestressed through generating recovery stress upon heating. The use of prestressing laminates is explored experimentally and their effectiveness in transferring compressive stress to the damaged regions is assessed using Digital Image Correlation (DIC) technique. Further, the effect of SMA thermal activation on the laminate’s cementitious material is investigated experimentally and an optimal heating method to minimize the impact on the laminate’s strength is proposed. Moreover, to investigate the durability of the proposed SMA-equipped laminates when subjected to harsh environmental conditions, accelerated aging protocol is adopted to study the corrosion resistance of prestressed SMA wires. Finally, finite element model is developed and calibrated to investigate the application of prestressing cementitious laminates to strengthen or repair damaged structures.
