Title (EN) STABILIZED REFRACTORY COMPOSITIONS
(FR) COMPOSITIONS RÉFRACTAIRES STABILISÉES
Abstract:
(EN) A refractory composition including refractory aggregate, one or more matrix components, and silicate-coated set accelerator particles. The silicate-coated set accelerator particles can include one more of silicate-coated calcium hydroxide, magnesium hydroxide, calcium chloride, calcium carbonate, magnesium carbonate and calcium sulfate. Suitable silicate coatings include sodium silicate, potassium silicate, lithium silicate and mixtures thereof. A method of recovering an aged refractory composition, a settable composition and a method of manufacturing silicate-coated calcium hydroxide particles are also provided.
(FR) L'invention concerne une composition réfractaire comprenant un agrégat réfractaire, un ou plusieurs composants de matrice, et des particules d'accélérateur de prise revêtues de silicate. Les particules d'accélérateur de prise revêtues de silicate peuvent comprendre un ou plusieurs composés parmi l'hydroxyde de calcium, l'hydroxyde de magnésium, le chlorure de calcium, le carbonate de calcium, le carbonate de magnésium et le sulfate de calcium revêtus de silicate. Les revêtements de silicate appropriés comprennent le silicate de sodium, le silicate de potassium, le silicate de lithium et leurs mélanges. Un procédé de récupération d'une composition réfractaire vieillie, une composition durcissable et un procédé de fabrication de particules d'hydroxyde de calcium revêtues de silicate sont en outre décrits.
