More Information
Summary:A colored cementitious composition is provided that is composed of hydraulic cement and a liquid coloring suspension. The liquid coloring suspension for cementitious compositions contains polycarboxylate dispersant, pigment, and a polysaccharide thixotropic additive. The liquid coloring suspension has improved viscosity consistency, improved shelf-life, anti- settling and anti- sludging properties, and decreased polycarboxylate dispersant requirements. Cette invention concerne une composition de ciment colorée qui est constituée de ciment hydraulique et d'une suspension colorante liquide. La suspension colorante liquide pour compositions de ciment contient un dispersant de type polycarboxylate, un pigment et un additif thixotropique à base d'un polysaccharide. La suspension colorante liquide a une consistance améliorée en termes de viscosité, une durée de conservation, et des propriétés anti-sédimentation et anti-boue améliorées, et des besoins réduits en dispersant de type polycarboxylate.
