摘要

A process for the preparation of compositions or Systems of Cement Mortar or Concrete (for reasons of Simplicity: Cement), (hereinafter compositions or Cement Systems for reasons of Simplicity) of a general kind known, where (S) mixture (S) of filling (n) is (or includes (n) in a mixture (S) of filling Calcium Carbonate based,It includes at least one step done this (S) mixture (S) is / are treated Filler (S) with a treating effective amount of at least one treating agent which consists of or includes superplasticizer (S); the main objective is to provide a process for systems or compositions Improved Cement or Mortar or concrete, High PerformanceFluids that have an improved Flow, improved Compactness, and in general terms, a definitely improved Manageability, and regularity of the properties of End Systems; and a mixture of Filler For Cement compositions, wherein consists of or includes a Mixture of filler Calcium Carbonate based or mixtures thereof,Pretreated with an effective amount of at least a superplasticizer.
