The machine (1) brings about artificial ageing of products (2) for building purposes and comprises a path (3) along which the products (2) are channelled, and a station (7) for ageing of the products (2), which is defined along a stretch of the path (3). The main characteristic of the present invention consists in the fact that the ageing station (7) comprises at least one rotating roller (13) with axis of rotation orthogonal to the direction of advance of the products (2) and at least one projection (18) made on the roller (7) and designed to come into contact with the products (2) in order to erode and hence age them.
