    Abstract: The present invention provides: a cement/asphalt mixture comprising an aggregate, an asphalt emulsion, cement, a hydraulic inorganic material and water, characterized in that the surfaces of aggregate fragments are covered with the asphalt particles prepared by the coalescence of asphalt emulsion and that the hydraulic inorganic material and water are present in the interstices between the aggregate fragments; a process for preparing a cement/asphalt mixture, the process being characterized by the steps of adding 2 to 12 parts (in terms of solids content) of a cationic or anionic asphalt emulsion to 100 parts of an aggregate; mixing them; and mixing the resulting mixture with 1 to 20 parts of a hydraulic inorganic material; and a process for preparing a cement/asphalt mixture, the process being characterized by the steps of adding 2 to 12 parts (in terms of solids content) of a cationic or anionic asphalt emulsion to a mixture of 100 parts of an aggregate and 0.1 to 6 parts of an alkaline compound of a bivalent metal; mixing them; and mixing the resulting mixture with 1 to 20 parts of a hydraulic inorganic material.

    Abstract: A material for treating heavy metals and metal ions. The material contains as its main components quicklime and cement, and also contains, with respect to the quicklime and the cement, 0.05 to 0.35% by weight of potassium chloride, 0.03 to 0.20% by weight of magnesium chloride, 0.03 to 0.20% by weight of sodium chloride, 0.03 to 0.25% by weight of calcium chloride, 0.00002 to 0.01% by weight of cobalt chloride, 0.00002 to 0.01% by weight of citric acid, and 0.001 to 0.02% by weight of sodium sulfate. Harmful heavy metals and metal ions contained in effluents, slurries and sludges can be securely and inexpensively confined in a state in which they are prevented from elution. A coating of a fatty acid may be formed on the surface of the quicklime.
