摘要：
Process for the preparation of "High performance", "HP", or "FLUID", or "technical", cement or mortars or concrete systems or compositions (hereafter for simplicity "cements" or "cements systems" or "cement compositions" or "cements" ) having an improved compacity, an improved flowability (and globally speaking a definitely improved "workability"; Product consisting of, or comprises, a blend of coarse (or optionally HP) "calcium carbonate ― based filler(s)" pre-blended with at least an UF; CEMENT COMPOSITIONS incorporating the said blend or aqueous composition, namely the said blend of low or medium (or optionally HP) coarse filler(s) treated with at least one UF; USE of the said blend, or aqueous compositions and cement composition.
