Abstract

A specific component of demolition waste from concrete and brick structures is the fines that remain after processing into granular recyclate and after sorting out the coarser fractions. In addition to brick and concrete recyclate, this can also include materials such as glass, ceramics (tiles, sanitary ware...), rubber and ornamental stone. These fine-grained wastes in this paper, a systematic review of fine-grained recyclates is elaborated with specification of their nature (inert-active) and a summary of their properties, or their modifications, to achieve the declared functionality. At the same time, an overview of the application possibilities (types of construction mixtures) in which the fines can contribute to the achievement of specific properties (e.g. self-compacting concretes, decorative plaster, mortars, railway concrete sleepers...).
