This document describes systems and processes for forming synthetic molded slabs, which may be suitable for use in living or working spaces (e.g., along a countertop, table, floor, or the like).

An apparatus including a first conveyor device including a first conveyor belt; a second conveyor device including a second conveyor belt; a movement device; and a mold device including a mold; wherein the first conveyor device is connected to the second conveyor device so that when the movement device moves the first conveyor device, the second conveyor device also moves with respect to the mold device; wherein the first conveyor belt moves independent of the second conveyor belt; and wherein the first conveyor belt and the second conveyor belt move independent from the movement device. The apparatus may further include a first and second dispensing devices configured to dispense first and second materials, first and second gate devices to control height, and a computer processor to control the various components and the resulting ratio of first material to second material in a processed slab.

This document describes systems and processes for forming improved synthetic molded slabs suitable for use in living or working spaces (e.g., along a countertop, table, floor, or the like).

A method of manufacturing a green body, the method comprising: providing: a third composition comprising a second substrate material, a third polymer, a fusing agent, and a third solvent; forming the third composition into a structure wherein the third composition forms a third layer; and contacting the third layer with a fourth solvent in which the third polymer is insoluble to precipitate said polymer, thereby forming a green body.

A substrate is further manufactured by: arranging a plurality of green bodies to form an assembly of green bodies;
fusing the green bodies in the assembly together, thereby forming a precursor substrate; and sintering the precursor substrate, thereby forming a substrate.

The invention relates to a concrete element comprising a core concrete layer and a face concrete layer, wherein the concrete element is obtained by compressing and curing a core concrete layer mixture in contact with a face concrete layer mixture, wherein the core concrete layer mixture contains a latent hydraulic core binder and/or a pozzolanic core binder, water, a granular core material and an alkaline core curing agent, wherein the face concrete layer mixture contains a latent hydraulic face binder and/or a pozzolanic face binder, water, a granular face material and an alkaline face curing agent, and wherein the concrete element has a compressive strength in accordance with DIN EN 12390-3, in particular DIN EN 12390-3:2019-10, measured after 28 days, of less than 120 N/mm.sup.2. The invention also relates to a method for producing the concrete element.

A pressing method for pressing ceramic slabs, comprising the following steps: spreading a layer (1) of granular or powdered material onto a pressing plane (2), wherein the layer (1) comprises at least a first zone (11), with a prefixed area and border, made of a granular or powdered primary material, and at least a second zone (12), with a prefixed area and border, made of a granular or powdered secondary material different from the primary material; pressing the layer (1) using a press (P); separating at least a main portion (10) of the first zone (11) from the second zone (12).

An apparatus including a first conveyor device including a first conveyor belt; a second conveyor device including a second conveyor belt; a movement device; and a mold device including a mold; wherein the first conveyor device is connected to the second conveyor device so that when the movement device moves the first conveyor device, the second conveyor device also moves with respect to the mold device; wherein the first conveyor belt moves independent of the second conveyor belt; and wherein the first conveyor belt and the second conveyor belt move independent from the movement device. The apparatus may further include a first and second dispensing devices configured to dispense first and second materials, first and second gate devices to control height, and a computer processor to control the various components and the resulting ratio of first material to second material in a processed slab.

The present invention relates to a method of manufacturing an artificial stone slab with veins comprises preparing a moldable hardenable fluid mixture of a first material (11); pouring said 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 said 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.
