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).

What is shown and described is a concrete element including a core concrete layer and a face concrete layer, the face concrete layer being obtained by compacting and hardening a mixture containing a latent hydraulic binder and/or a pozzolanic binder, water, a granular material and an alkaline hardener, with the granular material having, at a screen hole width of 2 mm, a through fraction from 35.5 wt. % to 99.5 wt. % and, at a screen hole width of 0.25 mm, a through fraction from 2.5 wt. % to 33.5 wt. %, each based on the total weight of the granular material.

A machine (1) for depositing ceramic powders comprises a supply device (2) and a distributor device (3) of the ceramic powders. The supply device (2) is configured to convey the ceramic powders receiving them from a process situated upstream of the machine. The distributor (3) is movable along a processing direction (X) which extends in a support plane and is configured to receive the ceramic powders from the supply device (2) depositing at least one layer thereof on the support plane during an advancement and/or reverse movement thereof along the processing direction (X). A system for making ceramic tiles or slabs is also claimed, comprising (i) the machine (1) for depositing ceramic powders, (ii) a conveyor belt (11) defining the support plane and (iii) a pressing device arranged along the support plane downstream of the machine (1) and configured to press at least one layer of ceramic powders deposited by the machine (1).

The present invention is related to materials of construction in the technical field of architecture and civil engineering, known as construction material for masonry; specifically, it is a compound made with a mixture of biodegradable cellulose matrix which is obtained from recyclable materials through an innovative method. Such compound, reaches higher resistance to compression in comparison to the known quality standards, even thought the resultant clusters, blocks or bricks, etc., are lighter due to their high cellulose content. This compound might be used, but not limited to, as raw material to produce hollow bricks, blocks, clusters and other conglomerates to build houses and buildings.

Machine and method for compacting a powder material; the machine comprises a compacting device, which is designed to compact the powder material; a conveyor assembly to transport the powder material along a first portion of a given path to the compacting device; and a feeding assembly, which is designed to feed the powder material to the conveyor assembly and comprises a transfer chamber designed to hold and transfer the powder material; movable elements are present at a wall of the transfer chamber.

An apparatus for spraying fluid phase color is integrated into a cladding manufacturing machine and synchronized with the manufacturing process. The apparatus is attached to the basket through which the concrete of the claddings is poured into a mould; color spraying initiates after completing the concrete filling phase of the manufacturing of the cladding and the basket retreats to its starting point. Color guns, attached to the basket, connect to color buckets and pump and condensed air pumps to deliver sprayed fluid color onto the top surface of the claddings. A control unit controls the color spraying via a sequential, parallel or pre-selected program or set of values of parameters that determine the final design or pattern on the claddings surface.

The present disclosure relates to a method for manufacturing a ceramic heater. The method for manufacturing a ceramic heater according to the present disclosure comprises: separately charging a ceramic powder into a center portion and multiple split edge portions in a formation mold and leveling the charged ceramic powder; manufacturing a molded body or pre-sintered body of the ceramic powder from the leveled ceramic powder; disposing a high-frequency electrode or a heating element on the molded body or pre-sintered body of the ceramic powder and filling a second ceramic powder; and integrally sintering the molded body or pre-sintered body of the ceramic powder and the second ceramic powder.

A machine for dry decoration of ceramic slabs or tiles, comprising: a support element (10), provided with a plurality of cavities (11) with a pre-established shape; a dispensing device (20), configured to deposit a pre-fixed amount of powder material inside one or more pre-established cavities (11); an unloading device (30), configured to move the cavities (11) from a loading position, in which they can receive the powder material from the dispensing device (20), to an unloading position, in which they can unload the powder material.

A paving block with improved illumination (luminescent paving block) preferably includes a concrete base layer and a photoluminescent layer. The photoluminescent layer is formed on top of the concrete base layer. The concrete base layer is preferably created by combining sand, aggregate, water, pigment and cement to form an uncured concrete mixture. The photoluminescent layer preferably includes very fine aggreagate, cement, water, pigment, sand and a polyester resin infused with a photoluminescent pigment or a silica-based glass material infused with photoluminescent pigment. Further, a light transmitting sealant may be placed over the photoluminescent material.

A method for decorating in thickness a ceramic slab, comprising the following steps: preparing, on a decoration surface (10), a first soft decorated layer (L1) of ceramic material endowed with a decoration (V); progressively transferring, by deposition, the soft decorated layer (L1) from the decoration surface (10) to a first deposition surface (50), situated at a lower height than the decoration surface (10), thus progressively forming on the first deposition surface (50) a second soft decorated layer (L2) which has a head (H) and a tail (T); progressively transferring, by deposition, the second soft decorated layer (L2) from the first deposition surface (50) to a second deposition surface (83), situated at a lower height than the first deposition surface (50), starting from the tail (T) of the second soft decorated layer (L2), thus progressively forming on the second deposition surface (83) a third soft decorated layer (L3).
