摘要： A process for preparing alkali silicate-polyisocyanate composites without catalyst separation. The process involves blending a catalyst and a polyisocyanate to form a first component, and blending an alkali silicate and water to form a second component. The first and second components are then mixed together to form a reactive mixture that reacts to form a hardened composite. The progression of the reaction proceeds without excessive foaming, high exotherms, or the release of an offensive odor. Sodium silicate-polyisocyanate composites prepared according to the above process, and a process for using the alkali silicate-polyisocyanate composites to consolidate and seal various types of formations in mining, tunneling, and other construction projects are also disclosed. Any void volume which is capable of receiving a flowable precursor of a composite formulation according to the invention prior to its cure is suitable for treatment according to the present invention.
