  • Method for compacting silica fume
    Patent number: 5160470
    Abstract: The present invention is a simple method for densifying colloidal silica. The method comprises feeding colloidal silica, recovered from a smelting process and having a density within a range of about 50 kg/m.sup.3 to 300 kg/m.sup.3, by a nearly horizontal feed means to a pair of vertically juxtaposed pressure rolls having surface depressions positioned so that the surface depressions of one roll corresponds to the undepressed surface portions of the other roll. The method does not require deaeration of the colloidal silica prior to densification and can be run as a continuous process. Colloidal silica densified by the present process is especially suitable for use as a reinforcing agent for concrete.
