    • The properties of cement matrices are improved by one or more of the three processes which can be performed individually, sequentially, or in any desired combination. In each instance a supercritical fluid including at least one substance other than CO.sub.2 is flowed through the matrix and the matrix is contacted by the substance to change, e.g. react, constituents of the two with each other. Alternatively, the supercritical fluid can be used as a solvent, itself or by combining it with a solvent which itself may or may not be supercritical, and the fluid is infused into the matrix to carry into the matrix and there deposit the dissolved material. This step can be repeated with another supercritical fluid which has a reactant for the material dissolved so that, upon the infusion of the second supercritical fluid, the initially deposited material and the reactant react to provide the matrix with desired characteristics. In a third alternative the supercritical material includes a solvent which itself may or may not be supercritical and which, upon infusion into the matrix passages, dissolves a selected material which can then be flowed out of the matrix.
    • 通过可以单独,顺序地或以任何期望的组合进行的三种方法中的一种或多种来改善水泥基质的性质。 在每种情况下,包括除了CO 2之外的至少一种物质的超临界流体流过基质,并且基质与物质接触以改变,例如, 反应,两者的成分彼此。 或者,超临界流体可以用作溶剂本身或通过将其与本身可以是或不超临界的溶剂组合使用,并且将流体输入基质中以携带到基质中并沉积溶解的材料。 可以用另一种超临界流体重复该步骤,该超临界流体具有溶解的材料的反应物,使得在输入第二超临界流体时,初始沉积的材料和反应物反应以提供具有期望特性的基体。 在第三种替代方案中,超临界材料包括本身可以是或不是超临界的溶剂,并且在溶入基质通道时溶解所选择的材料,然后可以将其从基质中流出。
