PROBLEM TO BE SOLVED: To provide cementitious formulations and their products with enhanced reactivity.SOLUTION: Formulations may include at least one calcium source, a reactant and a filler in a hydrated environment, where the reactant is crystalline silica that has been modified for reactivity. Enhancement of a reactant may include one or more modifications to its content, grind and/or cement-to-silica ratio, as well as addition of one or more additives in the formulation, i.e., additives in the form of at least one alumina source, defoamer, catalyst and/or clay. 【課題】反応性が強化されたセメント系配合物およびその製品の提供。【解決手段】配合物は、水和環境下で少なくとも１つのカルシウム源、反応物およびフィラーを含むことができ、該反応物が、反応性が改変された結晶質シリカである。反応物の強化として、その含量、粉砕度および／またはセメントとシリカの比に対する１つまたは複数の改変、ならびに配合物中の１つまたは複数の添加剤、すなわち、少なくとも１つのアルミナ源、消泡剤、触媒および／または粘土の形態の添加剤の添加である。【選択図】なし
