Definitions
- the subject of the present invention is a building element obtained by molding, the term molding having to be taken in the broad sense, and also covering other shaping techniques, such as spinning or extrusion.
- Building elements such as wall elements, lining partition elements, roofing elements, are often made of terracotta.
- a manufacturing technique consists, starting from a clay-based mixture, of making a paste containing about 20% of water, and of shaping this paste, by spinning and / or molding, in order to obtain elements which are completely first dried, then cooked, before they can be used.
- the object of the invention is to provide a building element obtained by molding, which is of a reduced cost price, and which has good physical and chemical characteristics, that is to say characteristics which meet its criteria. of use.
- the building element which it concerns contains as raw material clinkers for the incineration of household waste composed of different oxides such as: Si ⁇ 2, AI2O3, Fe2 ⁇ 3,
- silica is present for approximately 60%.
- the bottom ash can be used in the form of additions in other raw materials, such as clays, in proportions of 5 to 10% by weight, or constitute the main material of the element.
- clinkers are introduced into different types of terracotta, they improve its physical and chemical characteristics and in particular the resistance to acids, the characteristics of porosity and permeability, lower the baking temperature, which translates into energy savings, and plays the role of a degreasing agent, making the dough less plastic, and limiting the amount used.
- clinkers are used as the main raw material of the element, they can be used by preparing a hydraulic mixture, as is the case with clays, or can be used to obtain elements of lightweight construction. The objective in the latter case is to obtain light elements with good mechanical properties of thermal and acoustic insulation.
- a method for manufacturing a lightweight building element consists of clinker incineration of household waste containing different oxides such as: Si ⁇ 2, AI2O3, Fe2 ⁇ 3, CaO, NA2O
- a slip comprising 30 to 50% by weight of water and 0.8 to 5% by weight of binder, relative to the dry mass of bottom ash
- the bottom ash particles have a diameter of the order of 80 ⁇ m.
- the binder is an organic binder, constituted for example by corn starch.
- the foaming agent consists of an organic surfactant.
- this process consists in cooking at a temperature between 850 ° and 1000 ° C, advantageously 950 ° C, in an electric oven.
- This cooking cycle is adapted to the composition of the foam and to the shape of the part to be obtained.
- the shaping of the element is done by pouring in a monolayer or in a multilayer in a mold, in steel, resin, or synthetic material, possibly coated with an anti-adherent element such as polytetrafluoroethylene, with addition or not a release agent.
- the thermal, acoustic, mechanical and chemical characteristics of the foam product can be adjusted according to the application considered by varying the conditions for preparing the foam.
- the lightened construction element can also be tinted en masse, on the surface, engobed, enameled, raw, baked and annealed to adapt to aesthetic criteria.
- the construction element thus obtained can constitute a honeycomb wall element in the form of a brick, the dimensions and shapes of which are adapted to provide good mechanical resistance and good thermal insulation.
- a brick made of light material can for example have dimensions of 30 X 20 X 50 cm, with a degree of vacuum of 25%.
- the joints can be made with all types of mortars used in construction and the faces can be coated with all types of plasters, waterproof or not, used in construction.
- This building element can also constitute a lining partition, on one of the faces of which is fixed a layer of thermal insulation for example.
- the invention brings a great improvement to the existing technique, by providing a construction element in the composition of which come elements which are generally waste, and the treatment of which usually involves a significant cost. The use of such waste is of economic interest, allowing its reuse, and also ensures the production of building elements of excellent quality.
- the invention is not limited to only construction elements, nor to the single manufacturing process described above by way of examples, on the contrary it embraces all variants.
