[ES] La invención se refiere a un método para producir un compuesto de cemento, que comprende: 1) una primera etapa de acondicionamiento de nanopartículas de sílice, en las que las nanopartículas se calientan a una temperatura entre 85-235 ° C durante un intervalo de tiempo suficientemente largo para obtener un contenido máximo de humedad del 0,3% en relación con el peso total del material resultante del primer paso; 2) una etapa de dispersión seca, en la que las nanopartículas acondicionadas en la etapa 1) se dispersan sobre cemento y en la que se utilizan bolas de molienda inerte; 3) una etapa de acondicionamiento del compuesto de cemento obtenido en el paso 2), en el que las bolas de molienda se separan del compuesto de cemento producido. La invención también se refiere al material compuesto resultante, a derivados de cemento que comprenden dicho material compuesto, preferiblemente morteros y hormigón, al método de producción del mismo y al uso de estos materiales en la industria.
[EN] The invention relates to a method for producing a cementitious composite, comprising: 1) a first step of conditioning silica nanoparticles, in which the nanoparticles are heated to a temperature of between 85-235°C for a sufficiently long time interval so as to obtain a maximum moisture content of 0,3% relative to the total weight of the material resulting from the first step; 2) a dry dispersion step, in which the nanoparticles conditioned in step 1) are dispersed over cement and in which inert grinding balls are used; 3) a step of conditioning the cementitious composite obtained in step 2), in which the grinding balls are separated from the cementitious composite produced. The invention also relates to the resulting composite, to cement derivatives comprising said composite, preferably mortars and concrete, to the production method thereof and to the use of these materials in industry.
