摘要

Process for the preparation of compositions or cement mortar / concrete systems / load for compositions of cement, cement mortar or concrete compositions, application (s) of the process or of compositions or cargo, and products or elements of cement.The invention relates to a process for the preparation of compositions or cement systems / mortar / concrete (for reasons of simplification "cement), (hereinafter" cement compositions and systems' for sake of simplification), of a type known general, in which the load (s) (s) with Preende (m) or consists of (m) in the "load (s) based on calcium carbonate",Comprising at least a stage where (s) that (s) load (s) is (are) treated (s) with a quantity of effective treatment of at least a treatment agent consisting of superplastificantes (s) or including the (s).The main purpose of this invention is to build a process to provide the best systems or compositions of cement or mortar or concrete, the fluid of "high performance", as a better compactness, better fluidity and, in general, a 'workability' 'and' 'regularida 'definitely better the properties of end systems.The present invention also refers to a load for compositions of cement, characterized in that it is or comprises a load or combinations of the same base of calcium carbonate, pre treated with an "efficient" quantity of at least one superplastificante.
