<p>This invention presents a preparation of expanded silicate-based aggregates as useful in a method for absorbing hazardous liquid materials This expanded silicate-based aggregate material has previously been known for use as insulation, fireproof wallboard and insulating blocks, high temperature pipe covering, fire proofing of steel structures, marine deck filler and for cement block in non-bearing fire walls, but not for absorbing hazardous liquids. The present invention uses this aggregate material, either alone or mixed with a solution of five to seven percent of polyvinyl chloride in a solvent comprising 15% dimethylsulfoxide and 85% methylethyl ketone providing a paste which may be placed on a hazardous liquid material and within seconds will absorb the hazardous material throughout the thick paste material.</p> |
