Abstract: improved magnesium phosphate fast-setting cements can be prepared by treating ammonium phosphate fertilizer solution with an effective amount of an acidic phosphate additive. This additive can include polyphosphoric acid, orthophosphoric acid, monoammonium phosphate, monomagnesium phosphate and mixtures thereof. The fertilizer solution is treated with sufficient additive to reduce the pyrophosphate content of the fertilizer below 8 weight percent expressed as
P 2 0 5 . The treated ammonium phosphate fertilizer solution is capable of forming a fast-setting cement at ambient temperatures when mixed with a magnesium-containing compound and an optional aggregate.

Abstract: A solid phosphorus pentoxide containing material suitable for use in fast-setting cements can be produced by a process which comprises mixing a porous material with a liquid, phosphorus pentoxide containing material and heating the mixture until a dry solid is produced. The solid phosphorus pentoxide containing material thus formed can then be dry blended with a solid component comprising magnesium oxide, magnesium hydroxide, magnesium carbonate or mixtures thereof. An aggregate can optionally be added into this dry blend. The components of the resulting dry blend react in the presence of an aqueous component to form a monolithic solid.
