发明名称 Method for rapid molding of elongate concrete articles
摘要 An inner mold construction and an outer mold construction are provided to define a mold cavity or shape into which wet or uncured concrete is introduced. The method includes the sequential steps of compressing the concrete by movement of the inner mold relatively toward the outer mold to remove surplus liquid from the inner surface of the concrete so that the concrete is at least partially cured. The compression applied on the inner surface of the concrete by the inner mold is maintained while inward pressure is applied over the outer surface of the concrete by the outer mold to remove surplus surface liquid from the outer surface of the concrete. The inner and outer surface pressures on the concrete are released to release the molded article from the mold so that it may be separated therefrom.
