Abstract

Une famille de compositions de ciment contenant du calcium et du phosphate est divulguée. Le calcium est présent dans la matière de départ sous forme d'oxydes contenant du calcium tels que des silicates de calcium, des aluminates de calcium, des aluminosilicates de calcium et des verres comprenant du calcium et de la silice. Le phosphate est présent en tant qu'une ou plusieurs espèces de polyphosphate, telles que le triphosphate et le métaphosphate. Le polyphosphate est dissous dans l'eau et mélangé avec la matière de départ contenant du calcium, après quoi il est réglé pour former un béton dur et durable. Ces bétons offrent des performances améliorées par rapport au ciment Portland, telles qu'une résistance et une résistance chimique améliorées. Une caractéristique particulière de ces ciments est une liaison améliorée du ciment de prise avec des matériaux ou des agrégats de renforcement contenant du calcium, tels que le calcaire, le granit et la fibre de verre. D'autres caractéristiques comprennent l'émission de CO2 inférieure impliquée dans la fabrication de ciment par rapport au ciment Portland, et la capacité de l'hydrogel de phosphate de calcium formé lors du réglage pour séquestrer de nombreux radionucléides, y compris ceux présents dans des déchets de réacteur nucléaire.
