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.
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.
摘要:
The invention concerns a PROCESS for the preparation of cement / mortar / concrete (for simplicity: "cement") compositions or systems, (hereafter "cement" compositions or systems for simplicity), of a general known type, in which the filler(s) is/are comprising or consist of "calcium carbonate - based filler(s)" , comprising at least one step where the said filler(s) is / are treated with an efficient treating amount of at least one treating agent consisting of or comprising superplastifier(s). The main purpose of this invention is to build a process aimed at providing improved, "High performance", FLUID, cement or mortars or concrete systems or compositions having an improved compacity, an improved flowability, and globally speaking a definitely improved "workability", and "regularity" of the properties of the final systems. The present invention also concerns a filler for "cement" compositions, characterized in that if consists of, or comprises, a calcium-carbonate-based filler or blends of same, pre-treated with an "efficient amount" of at least one superplastifier.
摘要:
PROCESS for the preparation of cement / mortar / concrete compositions or systems, (for simplicity hereafter "cement" compositions or systems), featuring an improved compressive strength Rc namely at 28 days and 90 days, containing at least a "carbonate-based filler", comprising at least one step where the said at least one "carbonate-based filler" is mixed or blended with at least one aluminosiliceous material , and the obtained "fillers blend" is treated with an efficient treating amount of at least one treating agent consisting of or comprising superplastifier(s) ; PRODUCT comprising at least a " carbonate-based "filler" " as defined and at least an aluminosiliceous material, what provides a "fillers blend" ; CEMENT COMPOSITIONS, USE of the said "Fillers(s) blends" and cement composition ; CEMENT ELEMENTS or CEMENT PRODUCTS" obtained from the said "cements compositions", such as construction or building blocks.
