摘要： A base plate (1) for a plate compactor has a first surface (2) for use in initial compaction of material and a second surface (3) depending therefrom for final compaction of the material. The projected area of the second surface (3) is not more than substantially half of the projected area of the first surface (2).

摘要： A device for association with a rotatable powered roller (1) having an elongate cylindrical roll surface (2) adapted to be moved over a surface (9) of newly laid fluid and surrounding formwork (35), wherein the manner of association is such that the roller surface comprises an elongate substantially cylindrical texturing portion (2) and at least two guide portions (3), the guide portions (3) being adapted to support the texturing portion (2) at a required level with respect to the fluid surface (9) in manner to ensure partial embedding of texturing material distributed thereon, use thereof in texturing a fluid surface, method for texturing a fluid surface and a fluid surface obtained thereby.

摘要： A concrete-finishing apparatus (10) comprises a relatively quickly rotating, powered roller (18) adapted to be moved relatively slowly across a bed, slab or layer of newly-laid concrete (11), while the latter is still fluid, with opposite ends (14, 15) of the roller maintained at the required level of the concrete surface, in order to produce a smoothed finish to the surface of the concrete, said roller (18): a) containing internal stressing means (44) for applying longitudinal compression to the roller, between the ends (14, 15) of the roller, so as to reduce the tendency of the roller to sag or become permanently bowed; and/or b) being adapted to be removed from the remainder of the apparatus (10) and dismantled, when not in use, into constituent, smaller, parts.
