(EN) IMPROVED CEMENT COMPOSITION
(FR) COMPOSITION CEMENTEUSE AMELIOREE
Abstract
(EN)
The present invention concerns the field of cement, and relates particularly to phosphate cements. According to one aspect of the present invention there is provided a phosphate cement composition which comprises, in combination, a component A and a component B wherein the component A comprises an acid-treated wollastonite compound, an acid aqueous solution of metal phosphate, and a setting retarder; and component B comprises a setting accelerator.
(FR)
L'invention concerne le domaine des ciments, et notamment les ciments en phosphate. Selon un aspect de celle-ci, l'invention porte sur une composition de ciment en phosphate qui comprend, en combinaison, un composant A et un composant B. Le composant A comprend un composé de wollastonite traité à l'acide, une solution aqueuse acide de phosphate métallique, et un retardeur de prise; et le composant B comprend un accélérateur de prise.
