摘要

Procedure to prepare a cementitious composite, mortars and micro-nanostructured concretes with a long life in service, comprising said composite. The present invention relates to a process for the preparation of a cementitious composite comprising: 1) a first stage of conditioning of silica nanoparticles, in which they are heated to a temperature between 85-235º c, for a sufficient time interval to achieve a maximum moisture percentage of 0.3% with respect to the total weight of the material resulting from this first stage, 2) a dry dispersion stage in which the particles conditioned according to step 1) are dispersed on cement and in which inert grinding balls are used, 3) a stage of conditioning of the cementice composite obtained in stage 2), in which the used grinding balls are separated from the obtained cementice composite, To the composite obtained, to cement derivatives comprising this composite, preferably mortars and concretes, to its method of preparation and to the use of these materials in the industry.
