Geo-polymer concrete an innovative material that is characterized by long chains or networks of inorganic molecules is a potential substitution to ordinary Portland cement concrete for use in transportation infrastructure construction. It relies on minimumlly processed industrial by products to reduce its carbon footprint, while also being very resistant to many of the durability issues that can plague traditional concrete. However, the development of this material is still in its infancy, and a number of advancements are still required. This briefly describes geo-polymer concrete materials and explores some of their high strengths, weaknesses, durability and potential applications. In this paper we discuss the high strength of geo-polymer concrete.
