PROCESS FOR THE PREPARATION OF CEMENT, MORTARS, CONCRETE COMPOSITIONS CONTAINING A CALCIUM CARBONATE - BASED FILLER CONTAINING AN ORGANOSILICEOUS MATERIAL, THE SAID 'FILLER(S) BLEND' BEING TREATED WITH A SUPERPLASTIFIER, CEMENT COMPOSITIONS AND CEMENT PRODUCTS OBTAINED, AND THEIR APPLICATIONS

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.
