Sažetak:
Recycled aggregates have evolved towards a worthy alternative for natural aggregates. Therefore more applications with added value should be found for these kind of recycled aggregates that usually end up in low grade applications. This is the case for recycled concrete aggregates, recycled brick aggregates and mixed recycled aggregates which can find their wide use in building construction process where environmental influence on their durability and load bearing demands in use are considerably lower than for other applications. It is obvious that buildings are one of the biggest energy consumers and have a great impact on the environment not only because of their energy consumption in use but also because of the significant impact of building materials on the environment during production (significant embodied energy) and disposal. Therefore, the energy efficiency, sustainable construction and the use of recycled resources together with renewable energy sources are becoming priorities of contemporary construction process. ECO-SANDWICH is a ventilated prefabricated wall panel utilising recycled CDW and mineral wool produced using innovative and sustainable Ecose® technology for reduction of primary energy consumption in building stock. The inner (load bearing) layer of the ECO-SANDWICH is made of recycled concrete aggregates while the outer façade layer is made of recycled brick aggregates. In order to achieve the best ecology-to-quality ratio considering materials, appropriate selections should be made. Concrete mix proportioning is optimized in order to maximise usage of recycled CDW without the reduction of mechanical and durability properties. In the paper are shown results of testing mechanical and durability properties of the concrete mixtures produced with different amounts and different types of the recycled aggregate. As recycled aggregate, recycled concrete and recycled brick were used as replacement of the natural aggregate in amounts of 40 %, 50 % and 60 %.
