Presented and described is a method for manufacturing concrete elements having at least one concrete layer, wherein concrete for at least one element is introduced into a mould, the concrete is compacted by vibration and/or by tamping and subsequently cures, wherein to the concrete layer, prior to compaction, at least one portion of a granular material is applied by means of an application device, where the concrete introduced into the mould has a water/binder (w/b) ratio of 0.30 to 0.50 prior to curing and where as granular material a material is used comprising (a) a scatter component having an average particle diameter of 0.1 to 5 mm in an amount of 65 to 95 wt % and (b) binder in an amount of 5 to 35 wt %, based in each case on the overall composition of the granular material.

Provided is a building material manufacturing apparatus and a building material manufacturing method that are suitable for efficiently manufacturing a building material while suppressing clogging of a sieve portion for sieving the building raw material. The building material manufacturing apparatus of the present invention includes, for example, a sieve portion 10 and a receiving tool 30. The sieve portion 10 includes a receiving and sending sheet 11 with no sieve openings, onto which the building raw material M is dropped, and at least one sieve sheet 12 with sieve openings that is located below the sheet. The receiving and sending sheet 11 and the sieve sheet 12 can perform undulating motion, are inclined, and are arranged side by side in the inclination direction. The receiving tool 30 is for receiving the building raw material M that has passed through the sieve openings of the sieve portion 10. In the building material manufacturing method of the present invention, for example, in a state in which the receiving and sending sheet 11 and the at least one sieve sheet 12 are performing undulating motion, the building raw material M is dropped onto the receiving and sending sheet 11, moved from the receiving and sending sheet 11 onto the sieve sheet 12, subjected to sieving by the sieve sheet 12, and the portion that passes through the sieve openings of the sieve sheet 12 is accumulated on the receiving tool 30, whereby a mat with at least one layer is formed.

A material distribution apparatus and preparing an artificial stone plate using the material distribution apparatus includes a belt material distribution device including a material distribution hopper and a conveying belt. The conveying belt is located at a lower portion of the material distribution hopper. An upper surface of the conveying belt is inclined. The material distribution hopper has a first wall and a second wall. The first wall is an inclined wall with an upper end away from the second wall. A discharge outlet is provided below the second wall. An upper portion of the second wall is vertically mounted, and a lower portion of the second wall has a circular arc portion and a discharge portion which forms the discharge outlet with a surface of the conveying belt therebetween.

A method for manufacturing a part made of composite material includes injecting into a fibrous texture a slurry including at least one powder of refractory ceramic particles suspended in a liquid phase, filtering the liquid phase of the slurry and retaining the powder of refractory ceramic particles inside the texture so as to obtain a fibrous preform loaded with refractory ceramic particles, densifying the fibrous texture by treatment of the refractory ceramic particles present in the fibrous texture in order to form a refractory matrix in the texture. The method further includes, before injecting the slurry under pressure, pre-saturating the fibrous texture with a carrier fluid consisting in injecting into said texture a carrier fluid.

Station for the realization of coloring effects in a mix for the production of slabs, includes: a working surface intended to accommodate a temporary support with a basic mix layer for the formation of a slab; at least one dye dispensing device for emitting dyes towards the working surface so as to deposit them on the basic mix layer on the temporary support accommodated on the working surface; movement means for the relative movement of the dispensing device above the working surface; a control system connected to the movement means for controlling the displacement of the dispensing device so as to follow trajectories along which dyes are emitted towards the mix layer; at least one tool movable with the movement means (18, 118) and intended to interact mechanically with areas of the mix layer for receipt of the dyes emitted by the dispensing device to achieve coloring effects in the mix.

The present invention relates to a self-pouring mold system which ensures uniformity of a material by laterally pouring concrete into a mold installed on a side of a wall structure and minimizing a fall head generated when the concrete is poured to prevent bleeding, thereby ensuring uniformity of a fire-proofing material and adjusting a required fire-proofing coating thickness, and a method of fire-proofing, repairing, and reinforcing using the same.

A mobile autonomous printer includes a body, a plurality of hollow arms extending outwardly from the body, a pump system in each of the plurality of hollow arms, wherein the pump system in each of the plurality of hollow arms is switchable to extrude or take in material, and a vessel disposed within the body for mixing materials prior to deposition. Articulation of the hollow arms provides for mobility of the mobile autonomous printer. A method of building a structure includes printing portions of the structure using a plurality of printers and embedding the plurality of printers into the structure. The printers embedded in the structure may function as a network of switchable pumps. Distinct conduits constructed into the structure supply chemically reacting constituents of the material that forms the structure.

An apparatus for supplying material to a plant for producing slabs. The apparatus comprises means for supplying the material to be formed, first collecting and moving means, a conveyor cassette and second collecting and moving means. The means for supplying the material take the material from reservoirs and deposit it on the first collecting and moving means to form a semi-finished mat. The first collecting and moving means provide a stable base for the material and move the semi-finished mat towards the conveyor cassette, which receives the semi-finished mat and deposits a uniform pad on the second collecting and moving means. The second collecting and moving means provide a stable base for the uniform pad and move it towards successive stations in the plant. The conveyor cassette comprises at least one flap adapted to cross the entire thickness of the flow of material which, goes through the conveyor cassette.

A method of forming an aesthetic surface on a concrete structure. The aesthetic surface includes a mosaic design including a plurality of aesthetic elements, such as tiles, aggregate or the like, which are embedded within the hardened concrete structure. The aesthetic elements are affixed to the concrete form in the arrangement corresponding to the mosaic design prior to using the form during construction of the concrete structure. The concrete is poured into the form and allowed to harden, after which, the forms are stripped from the concrete, thereby exposing the embedded aesthetic elements within the concrete structure.
