Abstract

The concrete body consists at least partly of reflective concrete containing Portland cement, a hard filler, a pigment and crystal glass beads (E). The refractive index of the filler is at least approximately equal to that of the crystal glass beads. The particle size of the filler is smaller than that of the crystal glass beads. The crystal glass beads are approximately half exposed at the surface (D). Preferably the concrete body has a basic body (A) of normal grey concrete which is covered at least partly with a layer (B) of reflective concrete. In order to produce the concrete body, the dry components of the reflective concrete are mixed and water added. The resulting viscous mortar is either filled into a mould in an approximately 10 mm thick layer, the mould thoroughly vibrated and the concrete body pressed, or it is filled into a tubular hollow mould and moulded by centrifugal casting. After the concrete body is removed from the mould and allowed to harden, the surface of the crystal glass beads is exposed by etching with an acid. The concrete body can be used for reflective markings.
