Definitions
- the present invention relates to a method of creating patterns on a concrete surface.
- Concrete is the most manageable building material in the manufacture of elements that can have very different shapes and aspects.
- the deactivated concrete whose aggregates are apparent, allows in particular to decline in a wide range of aspects and colors. It is found on building sites (sidewalks, squares, car parks, courtyards, walks %) but also in the manufacture of street furniture (planters, garbage cans %), gravel tiles or wall panels.
- the final appearance of deactivated concrete depends mainly on its composition.
- the aggregates used can be of different sizes, shapes and colors (white marble, red rock ).
- the color of the cement can add a specific touch, since it can be chosen gray, white or dyed by a dye.
- US4055322 describes a process for creating patterns on a concrete surface comprising disposing in a mold a membrane having a water-permeable surface comprising, on one of its surfaces, patterns delimited by a setting-retarding agent. soluble in water, an impermeable film completely covering the patterns. The concrete is then poured on the membrane, on the permeable side with water.
- Patent application EP 1 177 081 discloses membranes comprising a deactivator creating patterns on said membrane. The membrane is placed at the bottom of the mold and the concrete is poured, deactivating the membrane to transfer the patterns of the membrane to the concrete.
- An object of the present invention is therefore to provide a patterning method on the surface of unmolded concrete, also referred to as positive deactivation.
- Another object of the present invention is to provide such a method which makes it possible to limit the appearance of unsightly bubbles or lenses of air on the surface of the concrete, in particular at the interface between the stencil and the surface of the concrete.
- the present invention relates to a method for creating patterns on a surface of a hydraulic binder composition, comprising depositing on the surface of the fresh hydraulic binder composition a stencil and then applying a deactivating composition (A ) on the surface thus covered.
- the method according to the invention may further comprise a step, prior to the deposition of the stencil, of applying, on all or part of the surface of the hydraulic binder composition, a deactivating composition. (B) having a lower attack force than that of the composition (A).
- the deactivating composition In contact with the surface of the fresh hydraulic binder composition, the deactivating composition penetrates by diffusion to a certain depth and induces a retardation of setting.
- the depth of the layer delayed by the deactivating composition also called digging capacity or attack force, will be chosen mainly depending on the size of the aggregates present.
- the objective is to make the aggregates appear on the surface, so the attack force will depend on the desired aesthetic effect as well as the size of the aggregates.
- the deactivating composition will have to be chosen according to the desired effect, typically the larger the aggregates, the greater the need for the composition to have a high attack force.
- the surface-delayed concrete layer remains friable and can be removed, so as to expose the aggregates to the surface of the workpiece, giving the material a particular aesthetic appearance.
- the delayed surface can be removed, after a delay of 8 to 24 hours, by washing with water jet under high pressure or by brushing.

It may for example, during the creation of the pattern, all or part of the surface, undergo a mineralizing treatment (or hardener), in particular to induce coloring. It can also, after creating the pattern, on all or part of its surface, be covered with a protective product.
- the protective product is typically applied to hardened compositions for the purpose of protecting it including external aggression. Such products are known to those skilled in the art.
- the treated surface may be both the surface of the areas intended to produce the pattern or the surface of the areas having the pattern, as the surrounding areas.
- the surface may also, after creating the patterns undergo mechanical treatments known to those skilled in the art such as polishing, sandblasting ...
- the invention also relates to an alternative method for creating patterns on a surface of a hydraulic binder composition, comprising depositing on the surface of the fresh hydraulic binder composition a stencil whose face in contact with the binder composition hydraulics is covered with a deactivating composition (C).
- the hydraulic binder composition, the stencil and the deactivating composition (C) are as defined above. Said method may further comprise aesthetic treatment steps as described above.
- the formwork is a steel formwork of dimensions 1 m * 4m * 0.10m in the bottom of which a polystyrene 2cm thick was placed.
- Flemish an American smoother still called Flemish.
- the stencil made of a Concrete Smooth®-type membrane, in which patterns have been cut is placed flat on the fresh concrete surface and smoothed again using of the same flamande in order to adhere the stencil to the surface.
- a deactivating agent in this case CHRYSO®Deco Lav P03, is sprayed on the entire surface using a CHRYSO®Pulvo Plastic sprayer. 22 hours later, the stencil is removed manually, then the surface thus discovered is completely washed using a high-pressure cleaner, which makes it possible to reveal the deactivated parts, while the parts in direct contact with the stencil remain smooth .
- the concrete surface obtained has smooth surfaces and deactivated surfaces showing patterns.
