Luping TangChalmers University of Technology, Sweden
Prof Tang received his PhD in 1996 at Chalmers University of Technology, Gothenburg, Sweden. Since then he has worked at SP Technical Research Institute of Sweden for 12 years and rejoined Chalmers since 2008 as professor and research leader for building materials. His main research interest is new types of cementitious materials and durability of concrete, especially chloride transport mechanisms and chloride induced corrosion of steel in concrete. He has over twenty years’ experience in the field of electrochemical applications in construction materials. He developed a rapid method called the RCM (Rapid Chloride Migration) test for testing resistance of concrete to chloride ingress. This method has got worldwide applications in many big construction projects and has been adopted as a standard test in many countries including Nordic, Switzerland, USA, and China. He also developed a rapid technique for corrosion measurement, again based on electrochemical principle.

Abstract
Cement-based concrete is the most widely used building and construction material in the world. Although concrete itself is relatively durable when used under the mild environments, its intrinsic weak mechanical strength greatly limits its application due to its porous structure. Graphene is a 2D layer material with very high intrinsic strength and Young’s modulus. Its planar structure is beneficial for bonding on the upper and bottom surface in close distance with the hosting material such as cement hydrates so as to be able to enhance the properties of the hosting material. This presentation highlights the development of graphene-enhanced concrete for building and infrastructures. In our ongoing projects we intend to develop low cost functionalized graphene for enhancement of the fundamental properties of brittle cement-based materials. The research is in a holistic way covering nano-scale study and macro-scale proportioning from nano-modifications to macro-applications with the help of eco-labeling tools so as to achieve a new generation of cement-based concrete with markedly enhanced mechanical properties and durability, contributing to sustainable building structures and civil engineering infrastructures with desired long service life and optimal balance with economic and ecological aspects.
