A multi-zone cementitious product, which includes a base zone made of a first cementitious material composition and forming a portion of the product. At least one facing zone is adjacent to and bonded to the base zone, the facing zone made of a second cementitious material composition and forming at least one exterior face of said product which is visible when the product is installed. A disrupted boundary layer is between the facing zone and the base zone, and includes material from both the facing zone and the base zone. The disrupted boundary layer bonds the facing zone to the base zone. The facing zone has a thickness sufficient to prevent the base zone from being visible when the product is installed.

A set comprising a plurality of covering elements for floors and/or walls, wherein each covering element comprises an upper surface having a pattern and at least one distressed upper edge, wherein at least two covering elements of the set comprises substantially the same pattern, and wherein the shape of the distressed upper edge differs in each covering element of the set.

A method of fabricating a barrier layer on a substrate includes mixing gettering particles, diffusive particles, and matrix material in a carrier fluid to form a slurry; applying a layer of the slurry to the substrate; adjusting the surface of the layer of the slurry; and sintering the layer of the slurry to form a barrier layer. An article is also disclosed.

A device (1, 1′) is depicted and described for processing concrete blocks (2), including: a transport device (3) for the transport of concrete blocks (2), and means (4, 4′) for the mechanical processing of the edges of the concrete blocks (2), wherein the means (4, 4′) for the mechanical processing are arranged above the transport device (3). In order to be able to process the concrete blocks (2) in a constructively simple manner with low mechanical stress, it is proposed, to pivot-mount the means (4, 4′) for the mechanical processing. In addition, a method for processing concrete blocks (2) is depicted and described.

A decorative concrete with a very uniform finish surface and a method of fabricating the same is disclosed. A concrete mixture is poured over a subgrade which defines an exposed surface. The exposed surface is finished with any of several techniques, and the surface is then worked with an abrasive material, and additional techniques are used to color and seal the concrete.

A bond sublayer is applied to a part and a ceramic layer is deposited on the bond sublayer by plasma spraying. The ceramic layer is then sintered.

A technique is described for the application of three-dimensional (3D) relief to a substrate such as a ceramic tile using digital inkjet technology. In an example embodiment, the introduced technique includes application of binder ink to a portion of the surface of a substrate using a digital inkjet process. This binder ink forms a barrier layer which protects the portion of the surface of the substrate. Next, a brushing process is applied to remove unprotected portions of the substrate, thereby forming the 3D relief in the substrate.
