    • A method of designing a cement composition comprises determination of the temperature to which the composition will be exposed in situ; determination of a stable, thermodynamic equilibrium composition of a CaO—Al2O3—SiO2—H2O (CASH) mineral system in the [xonotlite/wollastonite]-grossulaire-anorthite or grossulaire-anorthite-quartz triangles of the Si—Ca—Al phase diagram with a possible contribution of iron and/or magnesium, analogous to the cement when set, at the determined temperature; determining proportions of cement and mineral oxides required to provide a mixture having the determined composition; and defining a series of particulate materials of predetermined particle sizes and densities, comprising cement and mineral oxides in the determined proportions.
    • 一种设计水泥组合物的方法包括测定组合物将在其上原地暴露的温度; 测定CaO-Al 2 O 3 -SiO 2 H 2 -SiO 2的稳定的热力学平衡组成, O(CASH)矿物系统在Si-Ca-Al相图的[xonotlite /硅灰石] - 石榴 - 钙长石或粗铜 - 长石 - 三角形中,具有铁和/或镁的可能贡献,类似于当凝固时的水泥 ,在确定的温度下; 确定提供具有确定组成的混合物所需的水泥和矿物氧化物的比例; 并且确定一系列具有预定粒度和密度的颗粒材料,其包含所确定比例的水泥和矿物氧化物。
