A method and a plant (i.e., system or assembly) for manufacturing ceramic products comprising the steps of feeding a mixture of ceramic powders so as to obtain a powder material strip; compacting the powder material strip so as to obtain a compacted powder layer; acquiring a surface image of the compacted powder layer that reproduces the respective surface chromatic effects; processing said surface image so as to obtain a graphic decoration to be applied on the surface of the compacted powder layer that is coordinated with the respective chromatic effects in the thickness; and printing the graphic decoration on the surface of the compacted powder layer.

A method for producing microencapsulated fuel pebble fuel more rapidly and with a matrix that engenders added safety attributes. The method includes coating fuel particles with ceramic powder; placing the coated fuel particles in a first die; applying a first current and a first pressure to the first die so as to form a fuel pebble by direct current sintering. The method may further include removing the fuel pebble from the first die and placing the fuel pebble within a bed of non-fueled matrix ceramic in a second die; and applying a second current and a second pressure to the second die so as to form a composite fuel pebble.

The present disclosure relates to a method of forming a waffle slab with concrete surfaces that do not require polishing, the method comprising: providing steel molds connected to each other, and forming a space in the steel molds, wherein at least one of the steel molds has a hole; disposing a plurality of inner molds in the space formed by the steel molds; disposing predetermined steel bar cages between the plurality of inner molds, and between the plurality of inner molds and the steel molds; disposing a steel plate on top surfaces of the steel molds, wherein the steel plate comprises separate air holes; and pouring a Self-Compacting Concrete (SCC) into the space from the hole of the at least one of the steel molds such that the SCC fills the space to form the waffle slab.

A mold system for a modular telescoping barrier and method of construction provides barriers arranged in a telescoping configuration with tight tolerances. The barriers are constructed with an inner and outer mold subassembly, separated by a gap. A shape-adapted funnel pours mold filling into gap between mold subassemblies. When mold filling dries, the mold subassemblies are removed to access a barrier. Barriers are nested with other barriers having incrementally larger or smaller perimeters to achieve telescoping configuration. A base barrier with a support flange supports multiple barriers. The inner and outer subassemblies are made up of individual panels fitted together end to end, and at corners in a tight relationship. Reinforcing structures abut the panels to prevent panels from bulging. The narrow end of the funnels includes clamps that press inwardly on the panels to prevent bulging. A level and an agitating mechanism enable mold filling to be poured uniformly.

A method of manufacturing an artificial stone slab with veins comprises preparing a moldable hardenable fluid mixture of a first material (11); pouring the mixture into a mold (20) an upper face being exposed; engraving the exposed upper face with a predefined precise pattern of grooves (30) coinciding with a pattern of thin veins to be obtained; impregnating at least the inner faces (31) of the grooves (30) with a moldable hardenable fluid mixture of a second material (12), the color of both materials being different; causing the collapse and closure of the grooves, a visible pattern of thin veins of a second material with a natural look being left behind; curing the artificial stone slab by subjecting it to vibration, compression and vacuum until the fluid mixtures of the first material and of the second material are hardened.

A mix dispenser (14) comprises a hopper (24) with a top opening (26) for filling the hopper with a predetermined amount of mix and a bottom opening (28). The dispenser comprises a conveyor (30) which forms the bottom of said hopper (24) and is designed to extract the mix from the hopper (24) and convey it towards an end from where it falls into a mould. The dispenser is characterized in that said conveyor (30) comprises a supporting meshwork (32) made of a material resistant to the vapours of solvents such as styrene and operated by an electric motor (34). Furthermore a plant comprising such as dispenser is also described.

Device (1) for pressing a non-hardened concrete composition (12) into a desired form, whereby the device comprises an upper plate (4) with one or more first cavities (7) that run through the upper plate (4), a moulding plate (3) with one or more second cavities (9) whereby the upper plate (4) is located directly above the moulding plate (3), a bottom plate (2) located under the moulding plate (3) whereby the bottom plate closes the one or more second cavities (9) on the bottom, whereby the upper plate (4) and the moulding plate (3) can move horizontally in relation to each other between a first position in which the one or more first cavities (7) are directly and exactly above the one or more second cavities (9) and a second position in which the one or more first cavities (7) are not above the one or more second cavities (9), wherein the thickness of the upper plate (4) and not the thickness of the moulding plate (3) is decisive for the thickness of the final article (12,13

In an exemplary embodiment, a flexible mat forming system includes a rotating drum having a plurality of mold cavities about an outer periphery thereof; a hopper positioned adjacent the drum, the hopper shaped to receive a hardenable paste and deposit the hardenable paste into successive mold cavities of the plurality of mold cavities facing the hopper, as the drum rotates relative to the hopper; wherein the hopper includes an opening shaped and positioned to align with the mold cavities facing the hopper; and a sheet of mesh material that is fed between the hopper and the mold cavities facing the hopper.
