Abstract

La invención hace referencia a formulaciones de bajo costo basadas en un aglutinante alcalino activado. El material para construcción del tipo hormigón, contiene arena, agregados finos y gruesos, agua y un aglutinante que comprende: desde 55 a 80% en peso de ceniza volátil que contiene menos del 8% en peso de CaO; - desde 15 a 40% en peso de escoria de alto horno; y un activador químico que contiene desde 0.8 a 4% en peso de silicatos alcalinos y/o desde 1.5 a 9% en peso de carbonatos alcalinos; en donde el activador químico tiene silicio para una proporción molar de álcali desde 0.1 a 0.55; un impulsor que comprende al menos una base fuerte. La invención también hace referencia a un método para la producción de tal material de hormigón para la construcción. 1.- Un material para la construcción del tipo hormigón, que contiene arena, agregados finos, agregados gruesos, agua y un aglutinante que comprende: - Del 55 al 80% en peso de ceniza volátil con un contenido inferior al 8% en peso de CAO; - Del 15 al 40% en peso de escoria de alto horno ; y, - Un activador químico que contiene: o Del 0,8 al 4% en peso de silicatos alcalinos; y, o Del 1,5 al 9% en peso de carbonatos alcalinos; o En donde el activador químico tiene una ratio molar de sílice/álcali del 0,1 al 0,55; - Un impulsor que comprende por lo menos una base fuerte. 2.- Material de construcción del tipo hormigón de conformidad con la reivindicación 1 en el que el aglutinante se mezcla con agua con una ratio de agua/aglutinante situada entre 0,3 y 0,45. 3.- Un material de construcción del tipo hormigón de conformidad con cualquiera de las reivindicaciones 1 ó 2 en el que el impulsor se disponga para establecer el pH del agua en valores situados entre 12,1 y 13,75. 4.- Un material de construcción del tipo hormigón de conformidad con cualquiera de las reivindicaciones 1 a 3 en el que el impulsor comprende por lo menos una base fuerte, la concentración molar de la(s) base(s) fuerte(s) mencionada(s) situada entre 0,05 y 2,5 con respecto al contenido del agua. 5.- Un material de construcción del tipo hormigón de conformidad con cualquiera de las reivindicaciones 1 a 4 en el que la(s) base(s) fuerte(s) es un álcali fuerte.The invention relates to low cost formulations based on an activated alkaline binder. The concrete construction material contains sand, fine and coarse aggregates, water and a binder comprising: from 55 to 80% by weight of volatile ash containing less than 8% by weight of CaO; - from 15 to 40% by weight of blast furnace slag; and a chemical activator containing from 0.8 to 4% by weight of alkali silicates and / or from 1.5 to 9% by weight of alkali carbonates; wherein the chemical activator has silicon for a molar ratio of alkali from 0.1 to 0.55; an impeller comprising at least one strong base. The invention also refers to a method for the production of such concrete material for construction. 1. A material for the construction of the concrete type, which contains sand, fine aggregates, coarse aggregates, water and a binder comprising: - From 55 to 80% by weight of volatile ash with a content of less than 8% by weight of CAO; - From 15 to 40% by weight of blast furnace slag; and, - A chemical activator containing: o 0.8 to 4% by weight alkali silicates; and, or 1.5 to 9% by weight of alkali carbonates; o Where the chemical activator has a silica / alkali molar ratio of 0.1 to 0.55; - An impeller comprising at least one strong base. 2. Construction material of the concrete type according to claim 1 wherein the binder is mixed with water with a water / binder ratio between 0.3 and 0.45. 3. A construction material of the concrete type according to any one of claims 1 or 2 wherein the impeller is arranged to establish the pH of the water at values between 12.1 and 13.75. 4. A concrete construction material according to any of claims 1 to 3 wherein the impeller comprises at least one strong base, the molar concentration of the strong base (s) mentioned (s) between 0.05 and 2.5 with respect to the water content. 5. A concrete construction material according to any one of claims 1 to 4 wherein the strong base (s) is a strong alkali.
