摘要
A process for the preparation of a filling, which can be injected into porous or fissured materials or into fine alluvia, comprises mixing a product in particle form with a liquid, e.g. water, in the presence of a deflocculation agent which separates the suspended particles from each other; keeping the suspension deflocculated in this way in a container for a time sufficient to permit the partial sedimentation of it; and drawing off the volume of deflocculated suspension present in the container above a given level.
