eGEO is an experimental development project which aims to develop new building materials to mitigate climate change by an efficient use of resources and raw materials.
Among the traditional industrial sectors, the highest environmental impact results from construction sector due to the manufacturing process of concrete. The use of Portland cement as raw material involves high energy requirements, use of mineral resources and the emission of about 8% of global CO2. This fact has increased the interest in developing alternative cementitious materials that minimize energy, use resources efficiently and allow sustainable design strategies, which will provide a new differentiation factor for business.
Considering the large volume of waste generated in certain industrial processes as the obtaining of metallurgical silicon or granite processing, the development of free cement concretes is introduced as an alternative able to absorb large amounts of residues.
Led by OHL, eGEO proposes the development of a new binder that not only requires less energy but also uses low cost materials to obtain binding agents with good properties in terms of mechanical resistance and durability. In this context, AIMEN proposes geosynthesis process by alkaline activation of aluminosilicate residues as a viable technology for geopolymers manufacturing, as cement substitutes. The eco-efficient concrete obtained from these binders will be evaluated as a sustainable building material in the long term.
