Composition, preferably dry matter, comprises a cement alkaline-resistant, redispersible polymer powder, in a proportion of more than 30 (preferably at least 40) wt.%, at least one hydraulically hardening binder based on silicates, preferably cement, and optionally water glass. Independent claims are included for: (1) a multi-chamber container comprising: the composition in a first chamber and optionally water and water glass in a second chamber, where the first and the second chamber are brought into connection with each other so that the materials are mixed with each other; or the hydraulically hardening binder based on silicates, preferably cement, and optionally water glass in a first chamber, and at least an aqueous dispersion of the cement alkaline-resistant, redispersible polymer powder and optionally water glass; and (2) bonding fiberboard under use of the dry matter. |
