Description

Mixture for making elements for building and elements for building obtainable with such a mixture
The present invention relates to a mixture for making elements for building such as bricks, wall tiles and floor tiles, elements for making floating floors, of any size and thickness .
In the prior art a large variety of elements for building is known, which elements are made of ceramic material, bricks or natural stones .
All the known types of elements for building require the use of natural materials, which affects, even significantly, the manufacturing costs of the product.
An object of the present invention is to provide a mixture for manufacturing elements for building that is cheap and enables elements to be obtained that have mechanical strength that is at least similar to the mechanical strength of known elements for building.
A further object of the present invention is to provide a mixture for manufacturing elements for building that enables coloured elements to be made that have homogeneous colouring, minimising the quantity of colouring substances used in the mixture .
A further object of the present invention is to provide elements for building that are manufacturable with the aforesaid mixture and can be implemented in such a manner that the connections between adjacent elements do not affect the entire thickness of the elements.
The objects of the invention are achieved with a mixture for elements for building according to claim 1 and with an element for building according to claim 9.

Granitic clay 2.5%-3.5%
Ceramic clay 2.5%-3.5%
Sand 1.5%-2.5%
Waste raw ceramic material 1.5%-2.5% Colouring substances (optional) 1.5%-2.5%
Bentonite 0.2%- 0.45% Fluidifying substance (optional) 0.4%-0.6% According to a further preferred embodiment of the present invention, the formulation of the mixture for elements for building is as follows:
Vitreous material 65%-78%
Allumina 2%-5%
Feldspar 9.5%- 15.5%
Granitic clay 2.5%-3.5%
Ceramic clay 2.5%-3.5% Sand 1.5%-2.5%
Waste raw ceramic material 1.5%-2.5%
Colouring substances (optional) 1.5%-2.5%
Bentonite 0.2%- 0. 5%
Fluidifying substance (optional) 0.4%-0.6% According to a particularly preferred embodiment of the present invention, the formulation of the mixture for elements for building is as follows:
Vitreous material 74%
Feldspar 12.95% Granitic clay 3%
Ceramic clay 3%
Sand 2%
Waste raw ceramic material 2%
Colouring substances (optional) 2.25% Bentonite 0.3%
Fluidifying substance (optional) 0.5%
According to a further particularly preferred embodiment of the present invention, the formulation of the mixture for elements for building is as follows:
Vitreous material 71%
Allumina 3%
Feldspar 12.95%
Granitic clay 3%
Ceramic clay 3% Sand 2%
Waste raw ceramic material 2% Colouring substances (optional) 2.25% Bentonite 0.3% Fluidifying substance (optional) 0.5% The elements for building obtained with the mixture according to the present invention have a mechanical strength that is at least equal to that of the elements for building made of ceramic material and further, owing to the presence of the glass in the mixture are substantially impermeable. This makes the elements for building particularly suitable for wall and floor coverings on the outside and inside of buildings and for making so-called floating floors.
A further advantage of the mixture according to the present invention lies in the fact that elements for building made with said mixture require, in wet-cutting operations, a smaller quantity of water than elements for building made with traditional ceramic mixtures. The reduction of the consumption of water for wet-cutting operations is quantifiable as approximately 3 litres for each square metre of cut elements, with a proportional reduction in the quantity of mud produced, which is calculable as approximately 1.16 kg for square metre of cut elements .
A still further advantage consists of the possibility of obtaining coloured elements for building with a uniform colouring by using a quantity of pigments that is much less than that which would be necessary to obtain the same result in the case of elements for building made with traditional ceramic mixtures, for example also less than 90%. This is due to the presence of glass in the mixture according to the invention.
Lastly, the elements for building made with the mixture according to the invention are completely recyclable, inasmuch as they are used, after being milled, to produce other elements for building.
In Figures 1 and 2 there is illustrated an embodiment of an element for building according to the invention, that enables floor or wall coverings to be made in which there are hot joints that extend for the entire thickness of the wall or floor covering, which ensures that no humidity or dirt in general infiltrate through the wall or floor covering. This is particularly advantageous in the case of so-called floating floor covering, under which electrical circuits or pipes are normally arranged, because there is no risk that humidity or dirt can penetrate through the joints of the flooring, reaching and possibly damaging the electric circuits and pipes below.
In the embodiment, illustrated in Figure 1, the element for building 1 comprises a first part 2 and a second part 3 that are superimposed on one another and both have the same size and shape, preferably quadrangular. The second part 3 is arranged in a staggered position with respect to the first part 2 so as to be displaced by a first distance D with respect to the first part 2, in a first direction that is perpendicular to a pair of sides opposite the first part 2 and displaced by a second distance Dl with respect to the first part 2, in a second direction that is perpendicular to said first direction. The element for building 1 according to the invention can be obtained by moulding, in a single body, or the first part 2 and the second part 3 can be made separately and fixed together subsequently by gluing. As can be seen from Figures 3, 4 and 5, by joining together a plurality of elements 1 a set 4 is obtained in which the joint lines G between adjacent elements 1 extend only half way through the thickness S of the set and no joint line extends through the entire thickness of the set 4.
The elements for building 1, can have a square, rectangular, or parallelogram shape.
