Title
(EN) IMPROVED GEOPOLYMER CEMENT
(FR) CIMENT GÉOPOLYMÈRE AMÉLIORÉ
Abstract
(EN)
The present invention provides a geopolymer cement, comprising: a geopolymer binder; and a setting control composition comprising: a viscosity control agent, a polymeric binder, and a retarding additive. The invention also relates to a geopolymer concrete comprising the geopolymer cement of the invention and aggregate material. The invention further relates to a method for controlling open time in a geopolymer composition, wherein a sufficient quantity of the setting control composition is added such that the open time is between 30 and 120 minutes. The present invention provides particular uses in construction of walls, flooring, and roofing, especially lightweight prefabricated panels intended to be used as structural, insulating or cladding elements.
(FR)
La présente invention concerne un ciment géopolymère, comprenant : un liant géopolymère ; et une composition de contrôle de prise comprenant : un agent de contrôle de viscosité, un liant polymère, et un additif retardateur. L’invention porte également sur un béton géopolymère comprenant le ciment géopolymère selon l’invention et du matériau d’agrégat. L’invention porte en outre sur un procédé de fabrication destiné à contrôler le temps de prise dans une composition géopolymère, une quantité suffisante de la composition de contrôle de prise étant ajoutée de sorte que le temps de prise soit compris entre 30 et 120 minutes. La présente invention concerne des usages particuliers dans la construction de murs, de sols, et de toitures, en particulier des panneaux préfabriqués légers prévus pour servir d’éléments structurels, isolants ou de revêtement.
