High performance concrete with SCM and recycled aggregate Wojciech Kubissa, Roman Jaskulski, Artur Koper, Marcin Supera Warsaw University of Technology Faculty of Civil Engineering, Mechanics and Petrochemistry SPECIAL CONCRETE AND COMPOSITES th International Conference EU legal regulations: Over the past years, numerous legislative acts regulating the waste management issues at the EU level have been adopted. Perhaps the most important document was the Framework Directive (2008) that obliges member states to participate actively in waste recovery and the so-called separate collection of waste „at source”. The Directive imposes the following targets and time limits on member states:  To introduce separate collection of waste such as metal, paper, plastics and glass by 2015,  To ensure re-use and recycling of the following fractions of municipal waste: paper, metals, plastics and glass at the level of min. 50% by weight, by 2020,  To ensure re-use, recycling and other ways of utilizing materials, incl. backfilling operations using non-hazardous construction and demolition waste, at the level of min. 70% by weight, by Sustainable development is one of the leading civilizational ideas. This term means such a development that satisfies the present needs without a limiting the possibilities of fulfilling the needs in the future.

High performance concrete with SCM and recycled aggregate Wojciech Kubissa, Roman Jaskulski, Artur Koper, Marcin Supera Warsaw University of Technology Faculty of Civil Engineering, Mechanics and Petrochemistry SPECIAL CONCRETE AND COMPOSITES th International Conference Conclusions It is possible to manufacture concrete with RCA of compressive strength exceeding 70 MPa, but it is necessary to use at least 500 kg/m 3 of cement, water reducer and SCM. It is possible to manufacture concrete with RCA of compressive strength of MPa with use of fly ash and 300 kg/m 3 of cement, but it is necessary to use high amount of good quality water reducer. Concrete with RCA, 300 kg/m 3 of cement and significant amount of waste materials retains good workability after on our since the begin of mixing. It is also waterproof and shows high resistance to corrosion hazards.
