Composición seca basada en aglutinante mineral y destinada a la preparación de una formulación húmeda curable para construcción
Composición seca a base de aglutinante mineral (a) y que incorpora al menos un Polímero SuperAbsorbente - PSA- (b) y un componente acelerador de fraguado (c), esta composición estando destinada a la preparación de una formulación húmeda para construcción y caracterizada por que: - comprende al menos una fuente de iones aluminio; - el aglutinante (a) no es una fuente de iones de aluminio; - el componente (c) comprende al menos una fuente de iones aluminio; -- la concentración de aglutinante (a) está comprendida en los siguientes intervalos de concentraciones, expresadas en % en peso seco de la composición y dadas en orden creciente de preferencia: [15-99,5]; [20-98]; [25-97]; [25-96]; [30-95]; -- la concentración del componente (c) está incluida en los siguientes intervalos de concentraciones, expresadas en % en peso seco de la composición y dadas en orden creciente de preferencia: [0,10-20]; [0,15-20]; [0,15-15]; [0,15-10]; [0,2-10].
The invention relates to a dry composition for the preparation of a wet formulation for the construction industry. The aim of the invention is to provide a dry composition that results in hardened products for the construction industry having an excellent compromise between its lightweight properties and mechanical properties; optimizing the hydration of the binder; and making possible a stable lightweight property without excessive increase in volume. To this end, the composition according to the invention is based on a mineral binder (a) and incorporates at least one SuperAbsorbent Polymer (SAP) (b) and an accelerator component (c), characterized in that it comprises at least one source of aluminum ions and, optionally, (d) a setting retarder, (e) an additional setting accelerator; (f) a water-retaining agent; (g) a filler; (h) a lightweight filler, (i) a water repellent; (j) a coloring agent; (k) fibers; (l) an anti-foaming agent; (m) a redispersible powder resin; (n) a rheological agent; (o) an air-entraining or foaming agent; (p) a gas-generating agent; (q) a fire retardant. The wet formulation obtained by mixing this dry composition with water, the methods for preparing this dry composition and the corresponding wet formulation, the construction products obtained from the wet formulation and the structures produced with these products, are other subjects of the invention.
