Abstract: Improved magnesium phosphate fast-setting cementitious compositions containing a synergistic combination of an oxy-boron compound and hydroxycarboxylic acid, or its salt or acid derivative. These compositions form a hardened mass when water is added at ambient temperatures. The incorporation of the oxy-boron compound and hydroxycarboxylic acid, or its salt or acid derivative within these compositions retards the initial setting time, increases the early compressive strength of the resulting hardened mass by allowing a reduced amount of water to be added to the compositions and increases the final compressive strength. These compositions include a solid activator containing a P₂O₅ material, e.g. ammonium phosphate fertilizer, absorbed onto a porous material, e.g. diatomaceous earth.

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 translation: 通过用有效量的酸性磷酸盐添加剂处理磷酸铵肥料溶液可以制备改进的磷酸镁快速凝固水泥。 该添加剂可以包括多磷酸，正磷酸，磷酸一铵，磷酸一镁及其混合物。 肥料溶液用足够的添加剂处理，以将磷肥的焦磷酸盐含量降低到低于8重量％，表示为P2O5。 处理的磷酸铵肥料溶液在与含镁化合物和任选的聚集体混合时能够在环境温度下形成快速凝固的水泥。

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.
