PORTLAND CEMENT TO WHICH TEXTURED POZZOLANS ARE ADDED

摘要

The invention relates to different compounds of Portland cement to which textured pozzolans are added, said compounds being obtained by known physical atomisation, palletisation, granulation treatments or a combination of same, generating changes in the primitive global morphology of the compounds. These texturing processes enable special agglomerates having different morphologies to be obtained by the combination of a core of a defined material and a homogeneous layer which covers said core, improving the properties of the solid core constituent and facilitating the subsequent processing thereof, that is resisting the transformation of the solid aggregate from the moment of its genesis to the mixture and compaction thereof with the original cement, in order to obtain an optimum hardening speed. This type of textured granule reduces the immediate efficacy of the pozzolana, slowing down the reactions and enabling same to last longer with greater efficacy.
