CA 2591444

The invention relates to a process for the stabilization of dusting surfaces characterized in that the dusty ground is tilled or scarified and mixed with polymers in form of water-redispersible polymer powders, which are optionally reemulsifiably modified, or reemulsifiable modified aqueous polymer dispersions, which are optionally sprayed on to the untreated dusty ground. In a preferred embodiment the redispersible polymer powder, respectively the reemulsifiable modified redispersible polymer powder or the reemulsifiable modified aqueous polymer dispersion, is combined with hydraulically setting compounds, preferably cement and/or gypsum.

L'invention concerne un procédé de stabilisation de surfaces produisant de la poussière, caractérisé en ce que le sol poussiéreux est cultivé ou scarifié et mélangé à des polymères sous forme de poudres polymères redispersibles dans l'eau, qui sont éventuellement modifiées par réémulsion, ou à des dispersions polymères aqueuses modifiées réémulsionnables, qui sont éventuellement pulvérisées sur le sol poussiéreux non traité. Dans un mode de réalisation préféré, la poudre polymère redispersible, respectivement, la poudre polymère redispersible modifiée réémulsionnable ou la dispersion polymère aqueuse modifiée réémulsionnable, est combinée avec des composés à prise hydraulique, de préférence du ciment et/ou du gypse.
