The present disclosure describes architectural blocks configured to give the appearance of real cut stone. A fresh plaster composition may be applied to one or more surfaces of a block, such as a concrete masonry unit (CMU) to form an architectural block having the appearance of cut stone. The fresh plaster composition includes a cementitious component, such as white Portland cement, water, a limestone aggregate component, and optionally an adhesive component. The limestone aggregate component includes a fine sand portion and a coarse sand portion that effectively enable the appearance of cut stone after finishing of the hardened or curted plaster surface via sanding and/or polishing.

A precast composite wall structure and method for forming the wall structure are disclosed. The method includes providing a casting bed defining a plurality of shapes corresponding to a three-dimensional outer surface of a wall structure, placing a first layer of uncured concrete to conform to the shapes defined by the lower surface, positioning a forming member in overlying relation above the frame, the forming member defining a plurality of rectangular-shaped channels therebetween, positioning a stud frame within the casting bed along the forming member, placing a second layer of uncured concrete within the casting bed to conform to the rectangular-shaped channels between the rectangular protrusions, and allowing the concrete to cure.

A method for assembling a brick pattern for forming a precast brick panel. The method includes conveying bricks in a row to a spacing station, spacing the bricks apart in a row at the spacing station according to a predetermined row pattern and to a predetermined row length by allowing the spacing between adjacent bricks to vary if required. The method then involves transferring the row of spaced bricks onto a generally planar support surface of a brick pattern assembly station. By this method, a plurality of rows of spaced bricks are assembled adjacent each other on the support surface of the brick pattern assembly station to form a brick pattern.

The invention relates to a formwork element for a formwork system for concrete building purposes, in particular for integration into a construction plane of the formwork system, having a box-like supporting body (1, 2) facing away from the concrete, having an upper side (6) facing the concrete in use, having a recess (3) in the upper side (6) for the fastening of concrete-facing forming means (11; 11′; 35) which can be fastened on/in the recess (3), having a vacuum-permeable spacer (14; 17) having a plurality of passage openings (16), and having connection devices (7, 8, 9) for applying a vacuum, wherein a plurality of forming means (35) can be reversibly fastened by means of vacuum at the top side (6). The invention also relates to a formwork system having such a formwork element and a concrete component which has been created with the formwork element or the formwork system.

The fresh plaster composition includes a cementitious component, such as white Portland cement, water, a limestone aggregate component, and optionally an adhesive component. The limestone aggregate component includes a fine sand portion and a coarse sand portion that effectively enable the appearance of cut stone after finishing of the hardened or curted plaster surface via sanding and/or polishing.

The present disclosure describes modular blocks configured to give the appearance of natural or cut stone. An aesthetic coating composition may be applied to one or more surfaces of a block having a low-density, such as an insulating concrete form (ICF), to form an modular block having the appearance of cut stone. The aesthetic coating composition includes a binder component, such as a cementitious binder made from white Portland cement, or a polymer binder such as an acrylic binder, an aggregate component, such as a limestone aggregate component, and optionally an adhesive component. The aggregate component includes a fine sand portion and a coarse sand portion that effectively enable the appearance of cut stone after finishing of the aesthetic coating surface via sanding, polishing, sandblasting, acid etching, acid finishing, or exposed aggregate finishing.

The invention relates to a pointing device (10) for pointing brickwork a method for pointing brickwork and use of the pointing device (10) for pointing brickwork. The pointing device comprises: ⋅—a support (12) that is configured for supporting a product (14) comprising brickwork; ⋅—a filling nozzle (20); ⋅—a pointing substance container (22) that is operatively coupled with the filling nozzle (20), wherein the pointing substance container (22) is configured for holding a pointing substance; ⋅—movement means (24) that are configured to position the filling nozzle (20) relative to the support (12); ⋅—a control unit (26) configured for ⋅—controlling the movement means (24); and ⋅—determining the amount of pointing substance in relation to a point; ⋅—a sensor (28) that is operatively connected to the controller (26), and is configured for sensing the location and size of the point; and ⋅—orientation means (30) that are configured to establish a relative position between the filling nozzle (20) and the support (12).

The limestone aggregate component includes a fine sand portion and a coarse sand portion that effectively enable the appearance of cut stone after finishing of the plaster surface via sanding and/or polishing.

Apparatus, systems, and methods for applying plaster compositions to block substrates to yield a product having the appearance of cut stone. An example apparatus includes: a manifold; a mold connected to the manifold with a channel to receive the block substrate; a delivery hose connected to a top of the manifold to deliver plaster composition to the manifold for application to the block substrate; a pressure release hose connected to the manifold; and a vibrating mechanism connected to the mold. A system further includes a conveyor that moves block substrates through the mold. An example method includes: wetting a surface of a block substrate; moving the block substrate through an application apparatus as described, applying a layer of plaster composition to a surface of the block substrate, vibrating the mold and block substrate during application of the plaster composition, and allowing the plaster composition to harden.

The invention is a machine for producing decorative aggregate G-layer on top surfaces of claddings in cooperation with a cladding manufacturing machine. The G-layer production machine may be integrated into the cladding manufacturing machine or a standalone machine. In both options, the machines synchronize the overlaying of the top G-layer with the manufacturing process of the claddings to ensure continuous production of multi-layer claddings with a decorative aggregate layer. The overlaying itself is done under controlled condition to produce homogenous distribution of the aggregates on the top surface of the claddings to provide them an aesthetic look.
