ADDICTION TO OBTAIN STRUCTURAL AND MORTAR CONCRETETHERMAL DRIVERS SECTOR OF THE TECHNIQUE
The invention is applied in the construction sector, in particular in the field of efficiency and sustainability of buildings that activate structures thermally and / or geothermally. BACKGROUND OF THE INVENTION
Efficiency and sustainability in buildings according to regulations or directives such as the European "Directive 2010/31 / EU of the European Parliament and of the Council, of May 19, 2010, on the energy efficiency of buildings", introduces a new concept " Almost Null Energy Consumption Buildings ", for air conditioning and cooling, the TABS system (Thermal / and Activated Building System) is used, this system consists of the thermal activation of the concrete structure of the building, offering a path for the passage of heat to exchangers, which can be geothermal or not, or both. The concretes that are currently used to activate these structures are the same concretes that are routinely used to build structures, this greatly impairs the effectiveness of active structures due to their poor thermal properties and making it an unsuitable product. The reason for this situation is that any modification of the thermal properties in the concrete would cause a considerable decrease in mechanical strengths making it impossible to use as structural concrete, and it is necessary to prioritize structural safety. Within the documents studied, such as US2009294743 and MXPA05011139, they write how to obtain non-thermal electrical conductive concrete, but they do not obtain it by means of an addition but by a concrete formulation. Document US2011155019 does use an addition but to obtain a concrete resistant to fire and high temperatures. And among others, the vast majority give solutions for thermal concretes that are for the improvement of thermal insulation by decreasing thermal conductivity, as in documents W02014006194, CN103570291, CN104108913, W02013151439, etc., but not to increase it, precisely those contrary to which are obtained in this invention. But of all these, none use the solution of the addition to the concrete or mortar to obtain a thermally conductive structural concrete or a thermally conductive mortar. The thermal addition is a unique product, with it a thermal structural concrete is obtained that has a resistant capacity for a structural concrete and differentiated thermal properties of any concrete and for mortars very high thermal characteristics are obtained. These properties make it especially suitable for use in foundations activated for very low enthalpy geothermal energy and / or for thermally activated concrete structures or also for injection mortars in geothermal probes.
Application No. 10/08/2015 2015 EPO 10/08/2015 Effective EXPLANATION OF THE INVENTION
The addition is a powdery formulation that, mixed to make a conventional concrete, produces a structural concrete with improved thermal characteristics (thermal conductivity A). Or also mixed with conventional mortars, thermal conductive mortars of very high thermal characteristics are obtained, especially for injection mortars in geothermal probes. Regarding the addition to the concrete, depending on the thermal needs of the building or the characteristics of the land, the amount of addition may be increased or decreased or the dosage of the addition modified, to adapt the thermal conductivity of the concrete, but still be structural. These improved thermal characteristics make it very suitable for the thermal activation of structures and / or for geothermal activation of the foundations of a building, obtaining greater efficiency and better sustainability. Regarding the addition to the mortar, depending on the thermal requirements of the building
or the characteristics of the land, the dosage of the addition may be modified, to adapt the thermal conductivity of the mortar. These improved characteristics make the mortar very suitable for injection mortars in geothermal probes, although the use in other mortars is not ruled out. The addition is a specific formulation product in each case that by varying one or more of the components of the addition its properties will be modified in particular the thermal conductivity of the concrete, which said property may be determined by specific standards (such as the UNE -EN 1745: 2013 or UNE-EN 12667: 2002) The thermal structural addition consists of three to six components according to their application:
• Fine aggregate (limestone or siliceous) of granulometry less than 4 mm, in a proportion that will vary from 0% to 95% with respect to the total weight.
• Fine (limestone or siliceous) of granulometry less than 0.064 mm, in a proportion between 0% and 95% with respect to the total weight.
• Superplastic powder additive of the polycarboxylic ether type or its derivatives. In a proportion between 0% and 15% with respect to the total weight.
• Viscosity modulating additive of the type cellulose ethers, biopolymers or their derivatives. In a proportion between 0% and 10% with respect to the total weight.
• Natural or synthetic graphite of high thermal conductivity. In quantities ranging from 0% to 45% with respect to the total weight.
• Graphene and / or carbon nanotubes (nanomaterials) to obtain the characteristics of high thermal conductivity. In quantities from 0% to 20% with respect to the total weight.
• Some pozzolanic material such as silica, pozzolana or fly ash smoke. In

amounts ranging from 0% to 95% with respect to the total weight. This addition is added in the mixer of the usual concrete plant together with a conventional concrete, which knowing its dosage (cement, water, coarse aggregate, fine aggregate, additive and / or other additions), in turn its mechanical strength and consistency. The dosage of the thermal addition is adjusted and the amount of addition per m3 is determined. If an increase in conductivity is necessary the graphite and / or graphene content would be increased and fine and fine aggregates would be adjusted to obtain a very compact concrete. It is recommended to use type I cement (Portland cement). Given the characteristics of the addition, the added concrete obtains special rheological characteristics, which among others causes that a self-compacting concrete is obtained, and therefore it is very compact and of high density. It can also be added to any mortar but especially for injection mortars in geothermal probes. There is no need to obtain mechanical resistance, but to improve thermal characteristics and injectability, therefore the content of fine aggregate is reduced or by completely replacing it with fines. PREFERRED EMBODIMENT OF THE INVENTION
Although the possible total dosages can be very high depending on the needs especially of mechanical resistance and conductivity, a preferred embodiment would be that concrete for a foundation of a building with geothermal energy where they wish to activate these foundations to use geothermal energy for efficient and renewable air conditioning. , without a high investment in a field of probes to complement 100% of the climatic needs and the possible sanitary hot water (ACS). A conventional concrete typified or designated as HA-30 / B / 20 / llb is the one used, it is recommended that the cement used be of the CEM 1 type, in the case of using a cement

5 of the CEM II type would require prior checks to avoid possible unexpected interactions. In conventional concrete it is not necessary to modify the dosage of cement, the usual additives for work (plasticizers), coarse aggregates and fine aggregates. But for the amount of water or ratio of a / c (water / cement) a
10 adjustment as a result of mixing with thermal addition.
For each mde of conventional concrete indicated (2,500 kg / m3), in this preferred embodiment 50 kg of thermal addition per m3 of conventional concrete is added. Thermal addition contains:
• 80% fine limestone aggregate smaller than 4 mm 15 • 13% fine limestone smaller than 0.064 mm
• 1.9% superplasticizer additive
• 0.1% viscosity modulator additive
• 5% conductive graphite in fine powder By adding it to the concrete described, a structural concrete of relation has been obtained
20 a / c of 0.57, of average resistance higher than 55 MPa, very dense and self-compacting. The thermal conductivity A around 3.5 W / (K-m), very convenient for a high-conductivity ground type granite, as it is in the preferred embodiment.
