The coloured concrete is obtained by powdering and smoothing of a mineral hardener colored on the fraiche surface of a concrete at the time of the waste, to him confèrer an ornamental colour with effects of material(subject), as well as very big industrial resistance of type!

Coloured concretes enter the field of application of the standard P 18-305, has this title, they answer in the conditions of dosage by binding equivalent, in the minimal resistances, and in the report water / maximum sociable disposition of their class of environment

Qualities

The Resistance in the wear and has the impact
The Resistance in the thermic shocks
Uniformity of surface
Speed of stake in function
Ease of adaptation to the different forms
Durability of the organization on several decades
Maintenance simplified after pulverizing of resins of finish

Material

- Bastaing or calepinage (stone, brick, pavement) for the coffering.
- Rake, shovel, trowel, clout, rule(ruler) of upgrade.
- Brush to be glued or broom.
- Product of cure.
- Atomizer provided with a buzzard scattering the product in goutelettes liqueur brandies.
- Joined PVC, scieuse in disc or calepinage.
- Vibrating needle, striker or settle(adjust).

Preparation of the colored concrete

Beforehand, the construction site must be protected to prevent the passage of vehicles, pedestrians and animals.

The ground: for a weak traffic, the ground must be unpacked(paid out) on a 45 cm height and filled(performed) with materials crushed on a 30 cm height. Superficial waters must be evacuated. For a more important traffic, a calculation of road must be studied.

The coffering: he can be traditionally realized with bastaings but the technique of the calepinage is deeply advised.

The calepinage and the joints PVC: typical materials stones, bricks, pavements create ornamental bands(strips) and serve as support points during the application. The coffering wood is so abolished. Placed in a sensible way, the calepinage also kills(abolishes) the joints which, otherwise, must be foreseen (in the case of a fibré concrete, all 25 m ², with the biggest lower length with 2.5 times the width).

Protection of the calepinage and the neighborhoods: pulverize or apply a product protecting the calepinage of the concrete projections

Iron framework: the coloured concrete is fibré, what allows to kill(abolish) the grate anti-fissurings the pose(installation) of which is always painful and delicate (the grate that must be at the middle height of the thickness of the concrete). A fibré concrete replaces on no account the grate of structure.
