Environmental issues are getting more and more relevant in several fields of human activities and the building industry is fully concerned by these concerns. Recycled concrete aggregates (RCA) can be produced by existing concrete members resulting by either industrial processes (i.e., precast structures) or demolitions of existing structures as a whole. Moreover, waste resulting from industrial processes other than the building industry (i.e., production of steel, management of glass, powders resulting from other depuration processes) could be efficiently disposed as concrete aggregates or employed as reinforcement for Fiber-Reinforced Concretes (FRC). The use of natural fibres can also result into an environmentally-friendly and cost-effective solution, especially in developing countries, because of the local availability of raw materials. In order to promote the use of concretes with recycled and/or natural constituents as construction materials, the compatibility between the non conventional constituents and the concrete matrix have to be deeply investigated and correlated to the resulting mechanical and durability properties of the composite. This is the main goal of the EnCoRe Project (www.encore-fp7.unisa.it), a EU-funded initiative, whose activities and main findings will be summarized in this paper.
