发明名称 Process for removing mortar residues from a jointed surface.
摘要 In order to prevent the surface of jointing mortar from receding relative to the surrounding stone surface after the action of a cleaning aftertreatment medium, a swelling jointing mortar is used. A cobbled arrangement is achieved, in which the stone edges (11) protrude plastically because the mortar surface (9) adjacent to the stones is slightly recessed (10). <IMAGE>
