【 摘 要 】

The construction and demolition waste constitute a quarter of all types of waste production. Recovery of this waste in other areas of the economy is a step in the right direction to achieve sustainable development. Department of Concrete and Masonry Structures at the Faculty of Civil Engineering of the Czech Technical University is concerned in the problematic of sustainable constructions by research on recycled materials. One of the focus is on replacing of natural aggregate by rubble concrete recycled from demolished concrete structures and use of the recycled aggregate in fibre-reinforced concrete with synthetic fibres. The research focused also on possibilities of the structural design of structures from investigated material. The investigations proved usability of fibre-concrete with recycled crushed concrete in certain applications. The composite has satisfactory material characteristics and its application would consume a great deal of recycled concrete aggregate. The paper will present the material parameters and its efficiency in examples of applications.
