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.
