Abstract
Accelerators for the reaction of high-silica aluminosilicates with water are selected from the group made of alkanolamines, reducing agents, sugars, sugar acids, carboxylic acids or their salts, amino acids or their salts, sulfamic acid, glyoxal, acetylacetone, pyrocatechol, nitrilotri(methylphosphonic acid), etidronic acid, mineral salts, or mixtures thereof. The binders include high-silica aluminosilicates and the accelerators and are used in construction materials.
Claims16
A method comprising applying an accelerator for the reaction of high-silica aluminosilicates with water, said accelerator being selected from the group consisting of alkanolamines, reducing agents, sugars, sugar acids, carboxylic acids and their salts, amino acids and their salts, sulfamic acid, glyoxal, acetylacetone, pyrocatechol, nitrilotri(methylphosphonic acid), etidronic acid, mineral salts, or mixtures thereof.
A binder based on high-silica aluminosilicate, said binder comprising or consisting of
- a) at least one high-silica aluminosilicate,
- b) at least one accelerator for the reaction of the at least one high-silica aluminosilicate with water, said accelerator being selected from the group consisting of alkanolamines, reducing agents, sugars, sugar acids, carboxylic acids or their salts, amino acids or their salts, sulfamic acid, glyoxal, acetylacetone, pyrocatechol, nitrilotri(methylphosphonic acid), etidronic acid, mineral salts, or mixtures thereof,
- c) optionally at least one co-binder,
- d) optionally further additives different from b).
