FR2607851A1 - Method for arbitrary colouring and its method for producing a decorative concrete surface - Google Patents

Abstract

The present invention relates to a method for arbitrary colouring for a decorative concrete surface. The various coloured zones can be obtained with very clear borders or can overlap, creating a sought-after artistic effect : a blurredness within the mass or take on the appearance of a logo, acronym, inverted writing.

Description

ARBITRARY COLORING PROCESS and ITS PROCESS
MANUFACTURE OF A DECORATIVE CONCRETE SURFACE
Or. Can manufacture according to this process, decorative surfaces and concrete surface treatment for the walls of buildings, for industrial aesthetics, plastic arts, sculptures, etc ...

 To date, there is the process fig. 1 to give a pattern and low relief sculpture, any number of copies by assembling joined modular elements each reproducing a part of the original low relief.

In other known methods, the Architect or the Artist may also wish to vary the texture and the color of the surface. This can be achieved by using aggregates of different types in the concrete used to form the concrete body; when the concrete has set, the part of the aggregate located on the surface is exposed, for example by sand blasting.

According to the invention, the method used consists in disposing
1) either by manufacturing upside down, that is to say, the decorative side below
2) either by vertical manufacture with formwork on the side facing to be decorated.

 In this second process, the arbitrary coloring effect is less controllable than in the first case, but offers the advantageous possibility of being included in the whole of the structure, the whole being carried out simultaneously.

 In fig. 1, elements of this kind can be used, by juxtaposition in any number of copies by jointed modular assembly, to constitute decorative assemblies, such as pavers, wall coverings. The slab is made upside down, i.e. underneath, in a mold (which can be vibrating), the bottom of which corresponds to the surface of the slab Fig. 3 and 4.

On the bottom 3, the side 10 is fixed with screws 4 (for demolding), the height of which determines, once the mold is filled (5), the thickness of the finished slab.

On the bottom 3 can be fixed elements of volumes and shapes at the discretion of the creator; these elements will appear hollow in the finished concrete slab (6).

 1) According to the invention, the arbitrary coloring process consists in mixing concrete or mortar separately with aggregates and powder or liquid color in containers separately.

 2) Like a painter disposing according to his inspiration or following a pattern previously drawn inside the mold Fig. 3 and 4, there are different zones or keys available, heaped with concrete, colored aggregates 2.

It is possible to have batten (9) or other round accessories, etc., to maintain in certain places, the mortar faster in its setting.

Thus, we will obtain quite clear demarcations (1) between the different zones where at certain points of junctions between them, can overlap (11), creating a desired artistic effect: a blurring in the mass, or taking on the appearance of logo (fig. 5), acronym, reverse writing ...

3) Strip and accessories are removed to place the following concrete on top; alternatively, an area may have a smooth, gray concrete surface (7) without exposing decorative aggregates at certain points.

4) Then fill with ordinary concrete to the level of the sides; may be included in the mass a mesh surface or welded mesh (8).

Then, if possible, vibrate slightly from below.

According to the invention, the method can be advantageously combined with other known methods, for example
- The surface or the surface layer of the aggregate is covered with slow cement to avoid setting of the cement grout and subsequently treated if necessary, washed or exposed, by sand blasting, etc.

Claims (3)

 1) Arbitrary coloring method and its method of manufacturing a decorative concrete surface, characterized in that edges (10) are screwed onto the bottom (3) whose height (5) determines the thickness of the finished slab. There are inside the mold thus formed1 different heaps and / or streaks (2), aggregate zones, mortar, colored concrete according to his inspiration or according to a previously drawn pattern (Fig. 5).  2) Method according to claim 1) characterized in that the separations between the different zones or colored aggregates can be obtained with very clean garbage (1); there is on the bottom of the mold batten or accessories  Q chosen, on which the streaks (2) will get a dividing line  1 searched. We can use an accelerator for the setting and we remove the accessories (9) to add the aggregates (2) which, at certain anointing points between them, can overlap (11) without waiting, and make setting simultaneously (11 ), creating a desired artistic effect: blurring in the mass or taking on the appearance (Fig. 5) of logo, acronym, reverse writing.  of the creator. These elements will appear hollow (positive negative) in the finished slab (Fig. 5).  3 Method according to claim 1) characterized in that relief patterns can be achieved (6) by fixing on the inner faoe of the formwork, 3vant the application of the zones (2). elements of volumes and shapes at will  Alternatively, an area may have a smooth, gray concrete surface of the same type as that of the mold filling.  o, Method according to claim 1) characterized in that the mold is then filled without delay, by ordinary concrete, including a welded mesh surface ,.
