    • 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.
    • 本发明涉及一种用于水泥/砂浆/混凝土的制备中(为简单起见:“水泥”)的组合物或系统中,一般的已知类型的(以下称“水泥”的组合物或用于简化系统),填料,其中(一个或多个 )是/是包含或由...组成“碳酸钙 - 基填料(S)”,其包括至少一个步骤,其中所述填料(多个)/在至少一个的有效处理量治疗用处理剂组成或包含 超增塑剂。 本发明的主要目的是建立在提供改进的,“高性能”针对一个过程,FLUID,水泥或砂浆或混凝土体系或组合物具有改善的密实度,以提高流动性,和全球说出一定的提高“可加工性” 而最后的属性“规律性”。 因此,本发明涉及一种填料为“水泥”的组合物,其特征在于确实如果besteht,或包含,基于钙碳酸盐填料或相同,预处理的共混物与至少一种超塑化剂的“有效量”。
