PRODUCTION OF SOLID PHOSPHORUS PENTOXIDE CONTAINING MATERIALS FOR FAST-SETTING CEMENTS ABSTRACT OF THE DISCLOSURE A solid phosphorus pentoxide containing material suitable for use in fast-setting cements can be pro- duced 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 compo- nent 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 mono- lithic solid.
