<p>The use of a mixture comprising a) alkaline reactive hydraulic binder, b) cellulose ether, c) propellant, d) filler as a tile adhesive is claimed, characterized in that the propellant c) is peroxo compounds and/or percarbonates and/or aluminum powder, and the tile adhesive mixture has a maximum and stable volume increase of 50 vol.-% within five minutes after the admixture of tempering water. This mixture, which can also contain further additives such as retarding agents, antifoaming agents, and polymer dispersion powder in addition to the four listed components, has the advantage that the propellant used reacts almost completely within 5 minutes and thus results in a volume increase of the tile adhesive mixture of at most 50 vol.-%. After it hardens, the mixture has a high intrinsic strength, but also a sufficient composite strength and adhesive tensile strength in regard to the system tile/substrate.</p> |
