Novel metallic alloys for fire resistant concrete composites (Advert Reference: SF19/EE/MCE/SANCHEZ)


Project Description

Concrete can be reinforced with a range of metallic materials among which steel is frequently used for its high strength at room temperature, however, the mechanical properties of carbon steel decreases beyond 300°C. The strength decreases even faster beyond 300°C (Lawson & Newman, 1990) and exhibit creep beyond 450°C. For this reason there is a need for novel metallic materials that can keep its performance for extended temperature range. In this regards, shape memory materials (SMAs) are of great potential for civil engineering applications (Chan & Araki, 2016) since they undergo large deformations and return to their un-deformed shape through stress removal or heating. In addition they exhibit good hysteretic damping properties and therefore could be of interest to enhance the structural and fire performance of buildings. One aim of this project is to develop novel cost-effective SMAs that can compete with more traditional metallic materials for their use in construction.

This project is supervised by Dr Sergio Gonzalez Sanchez.
