Abstract
The article presents the recycling technology of reinforced concrete formed during the renovation program in Moscow city. It is shown that the part of concrete can be recycled to obtain raw materials for self-compacting concrete use, including products of recycling. The products include recycled concrete aggregate 5-10 mm fraction and the filler. It is indicated that the efficient concept of recycling process is sorting of various types of products and removal of contaminants. The sequence of technological operations for dismantling buildings, transportation and recycling of concrete, storing and quality control of the resulting product has been developed. Technological methods that allow to obtain self-compacting concrete mixtures with the use of recycled concrete in concrete plant are suggested.
