Abstract

On January 1st 2012, the European project SUS-CON has been started: “SUStainable, innovative and energy efficient CONcrete, based on the integration of all waste materials” (grant agreement no: 285463). The SUS-CON project aims at developing new technology routes to integrate waste materials in the production cycle of concrete. It should result in an innovative light-weight, eco-compatible and cost-effective construction material, made by all-waste raw materials and characterized by low embodied energy and CO2 and by improved thermal insulation performances. The focus of the SUS-CON project will be on waste materials that, for quantity, distribution and characteristics are also a social problem but, on the other hand, are available in quantities enough for feeding the concrete industry. Identifying the waste materials is the objective of WP 1. The innovative all-waste material will consists of light weight recycled aggregates in a binder matrix, in equivalence to concrete. The LW aggregates consist of various waste streams, among which waste plastics not suitable for recycling into new products and melted and bound by waste gypsum, shredded and processed waste tyre, geopolymer aggregates and so on. The use of lightweight recycled aggregates will allow making the target material not only lightweight but also heat-insulating. The LW aggregates have been investigated and tested in WP 2. The binder consist of waste pozzolanes or latent hydraulic materials that are activated by waste activators. Upon mixing with water, they form a reaction product, serving as binder of the all-waste concrete. The binders have been investigated in WP 3.
