An article of manufacture including reinforcement material embedded in a phosphate cement composition is provided. The phosphate cement composition includes about 10 to 40 percent by weight calcium or magnesium oxide, about 10 to 40 percent by weight acid phosphate, and about 10 to 50 percent by weight vermiculite or perlite or mixture thereof.

Heat resistant phosphate cement

Waste storage vessels formed from a composition including calcium silicate, magnesium or calcium oxides and an acid phosphate are provided. The composition may also include fly ash or kaolin with or without the calcium silicate.

Waste storage vessels and compositions therefor

A phosphate cement composition is provided. The cement composition comprises about 10 to 40 percent by weight calcium or magnesium oxide, about 10 to 40 percent by weight acid phosphate, and about 10 to 50 percent by weight vermiculite or perlite or mixture thereof.

A sprayable and pourable cement composition is provided. The cement composition comprises about 30 to 40 percent by weight calcium silicate, about 20 to 35 percent by weight magnesium oxide and about 25 to 45 percent by weight monopotassium phosphate.

Sprayable and pumpable phosphate cement

A dry mix particulate composition of a calcined oxide of Mg and/or Ca, an acid phosphate, and fly ash or equivalent, wherein the calcined oxide is present in the range of from about 17% to about 40% by weight and the acid phosphate is present in the range of from about 29% to about 52% by weight and the fly ash or equivalent is present in the range of from about 24% to about 39% by weight when sand is added to the dry mix, it is present in the range of from about 39% to about 61% by weight of the combined dry mix and sand. A method of forming a structural member is also disclosed wherein an aqueous slurry of about 8&#x2013;12 pounds of water is added to dry mix and sand.
