    • A cementitious composition capable of forming high early strength cement when admixed with water may comprise, for each 100% by weight, no more than about 60% by weight C3S, at least about 4% by weight C2S, and between about 7% and about 11% by weight SO3, wherein the cementitious composition has a particle size distribution such that substantially all of its particles are of a size of about 10 microns or smaller. A cementitious composition may have a ratio of weight % SO3 to weight % Al2O3 of at least about 1.5 and a particle size distribution such that substantially all of its particles are of a size of about 10 microns or smaller. An apparatus and method for making such a cementitious composition are also described.
    • 当与水混合时能够形成高强度水泥的水泥组合物可以包含每100重量%,不超过约60重量%的C3S,至少约4重量%的C 2 S和约7重量%和约7重量% 11重量%的SO 3,其中所述胶结组合物具有使得其基本上所有的颗粒的尺寸大约为10微米或更小的粒度分布。 水泥组合物可以具有至少约1.5的重量%SO 3与重量%Al 2 O 3的比例,以及粒度分布,使得其基本上所有的颗粒的尺寸为约10微米或更小。 还描述了制造这种水泥组合物的装置和方法。
