Process for producing phosphomagnesia cements having reduced sensitivity to water

Phosphomagnesia compositions settable into improvedly water-insensitive cements that retain their mechanical properties comprise an intimate admixture of (i) a binder phase including (a) at least one phosphorous compound (P2O5 or derivative/precursor thereof) and (b) at least one magnesium compound...

Zusammenfassung:Phosphomagnesia compositions settable into improvedly water-insensitive cements that retain their mechanical properties comprise an intimate admixture of (i) a binder phase including (a) at least one phosphorous compound (P2O5 or derivative/precursor thereof) and (b) at least one magnesium compound reactive therewith in the presence of water, (ii) an effective amount of cementitious aggregate, and (iii) a water sensitivity-reducing amount of at least one silicone homogeneously distributed therethrough.
