摘要：
PROCESS for the preparation of cement / mortar / concrete compositions or systems, (for simplicity hereafter "cement" compositions or systems or even "cements" ), of a generally known type containing low or medium (standard) "filler(s)", and/or optionally HP filler(s), as carbonate - based filler(s), namely coarse low or medium calcium carbonate(s) , namely coarse marble(s) ; Product comprising, or consisting of, the pre - blend (A) of coarse , low or medium (or optionally HP) "calcium carbonate - based filler" pre-blended with at least an UF ; Aqueous compositions (B) obtained by mixing the above pre-blend (A) of coarse filler(s) with UF(s) with an aqueous system such as mix water, aqueous mix fluid ; Product (C) consisting of, or comprising,the pre-blend (A) or the compositions (B) , treated or pretreated with at least one superplastifier or aqueous system containing superplastifier(s) ; Cement and Use of cement.
