Aggregates are grained materials used in constructions, which can be of three types, namely; natural, synthetic or reclaimed. Natural aggregates are aggregates that are supplied from mineral sources and which are not held subject to any process except mechanical; synthetic aggregates are mineral based aggregates produced through industrial processes involving heat or other applications; and reclaimed aggregates are aggregates obtained by processing inorganic materials previously used in constructions. In the related standard, the aggregate that is composed of a mixture of coarse and fine aggregate particles is named mixed aggregate and the materials that are added into building materials with the aim of bringing in some features, the majority of which go through 0,063 mm mesh sieve, are specified as filler aggregates.
