    摘要： A method of incorporating a material in a settable binder is disclosed. The binder includes a source of caustic magnesium oxide. The method involves mixing the material with the binder, either as part of a slurry or for subsequent formation into a slurry, and then adding a setting agent to the slurry. The Setting agent is added to enhance setting of the binder. The material can be a hazardous waste material or components thereof. The inventors have surprisingly discovered that when the setting agent is added after mixing of the material with the binder, that a superior setting of the material in the binder can be achieved. The settable composition can comprise only a caustic magnesium oxide binder and a setting agent for the binder, as the inventors have surprisingly discovered that there is no need for any other binding agents, thus providing a simpler binder composition and method of use.

    摘要： Deadburned magnesium oxides (calcined at a temperature of above about 4000.degree. F.) can be advantageously utilized as an expanding additive in cements utilized to seal a metallic casing into the bore hole of a well. The deadburned magnesium oxide additives are particularly effective when used in cements having a curing temperature of about 120-200.degree. C. and particularly at temperatures greater than about 150.degree. C.

    摘要： A novel, non-combustible thin coating, applied as an air-setting paint, is used to form a coherent fire-barrier on or between susceptible wood or plastic substrates, or other substances. Consisting of a paint-like slurry of three separate but compatible and mutually synergistic co-bonding systems, viz. magnesium "oxychloride" cement, plus high alumina mono-calcium aluminate cement, plus colloidal silica dispersed in dimethyl formamide (DMF), and utilizing an aqueous solution of magnesium chloride as the common hydrating fluid for the two cements, the coating retains its structural integrity through prolonged exposure to flame temperatures of 2000.degree. F. The coating takes advantage of its brilliant whiteness to act as a thermal radiation reflector for the high radiation component of most flames. Used alone, or in combination with structural reinforcing geotextiles, such as non-woven spunbonded polyester fabric, or woven and non-woven fiberglass or other natural or synthetic fabrics to form a laminate, the coating, while serving only transitorily as a heat barrier, effectively prevents the ignition of and flame spread of fire on the coated substrate. When placed between substrates at the partial sacrifice of the surface directly exposed to flame, it protects the back-substrate, and thus maintains structural integrity, as well as preventing the spread of flame to adjacent areas. The coating thus acts as a "fire-barrier" for which there are numerous applications.

    摘要： Rapid setting magnesium phosphate (Mg glass) cementitious materials consisting of magnesium phosphate cement paste, polyborax and water-saturated aggregate exhibiting rapid setting and high early strength characteristics. The magnesium glass cement is prepared from a cation-leachable powder and a bivalent metallic ion-accepting liquid such as an aqueous solution of diammonium phosphate and ammonium polyphosphate. The cation-leachable powder includes a mixture of two different magnesium oxide powders processed and sized differently which when mixed with the bivalent metallic ion-accepting liquid provides the magnesium glass cement consisting primarily of magnesium ortho phosphate tetrahydrate, with magnesium hydroxide and magnesium ammonium phosphate hexahydrate also present. The polyborax serves as a set-retarder. The resulting magnesium mono- and polyphosphate cements are particularly suitable for use as a cementing matrix in rapid repair systems for deteriorated concrete structures as well as construction materials and surface coatings for fireproof structures.

    摘要： A highly stable metal oxide oil slurry useful in reducing slag, facilitating removal of deposits from boiler tubes, and reducing corrosion on the heating surfaces of boilers has been developed. Such a slurry consists essentially of about 50% by weight magnesium oxide or the entity of magnesium oxide and alumina oxide, together with an oil-soluble emulsifier such as alkanolamide and preferably ethanolamide, or an alkanol with a carbon chain greater than a C.sub.3 alcohol, an oil-soluble dispersant such as a C.sub.12 -C.sub.22 entity selected from an unsaturated or saturated fatty acid; e.g., oleic acid. Also, as a constituent is an anionic surfactant such as magnesium lauryl sulfate in an oil base such as No. 2 fuel oil. The alkanolamide is fashioned from heating alkanolamines and fatty acids either in a 1:1 ratio or 2:1 ratio. The reactant amino alcohol is in the range C.sub.10 -C.sub.24. The alcohol itself is greater than C.sub.3 and up to C.sub.16, with a preferred range C.sub.12 -C.sub.16.
