<p>The use of a mixture consisting of a) alkaline hydraulic binder, b) cellulose ether, c) blowing agent, d) filler as a tile adhesive is claimed, wherein the blowing agent c) comprises peroxo compounds and/or percarbonates and/or aluminum powder and wherein the tile adhesive mixture has a maximum and stable volume increase of 50% by volume within five minutes after admixing of water. This mixture, which may also comprise further additives such as, for example, retardants, antifoams and polymer dispersion powders, in addition to said four components, has the advantage that the blowing agent used reacts virtually completely within 5 min and thus leads to a volume increase of the tile adhesive mixture of not more than 50% by volume. After it has hardened, the mixture has a high intrinsic strength but also sufficient bonding strength and adhesive strengths with respect to the tile/substrate system.</p> |
