text: All of the gypsum-containing products described above could benefit if the strength of their component set gypsum crystal structures were increased in order to make them more resistant to the stresses they may encounter during use.
text: However, before the material strength reaches to the peak value, the water content is reduced and the strength is increased.
text: Some preferred embodiments of the invention concern making such products by hydration of calcined gypsum in the presence of an enhancing material that causes the set gypsum produced by such hydration to have increased strength, resistance to permanent deformation (e.g., sag resistance), and dimensional stability (e.g., non-shrinkage during drying of set gypsum).
text: When the water in the mixture reacts spontaneously with the calcined gypsum to form set gypsum, the set gypsum is unexpectedly found to have increased strength, resistance to permanent deformation (e.g., sag resistance), and dimensional stability, compared with set gypsum formed from a mixture containing no trimetaphosphate ion.
