Use of aliphatic hydrocarbons and hydrocarbon mixtures in powdery building chemical products

The invention relates to the use of hydrocarbons or hydrocarbon mixtures used as additives for the reduction of dusting of dry, in particular pulverulent construction chemistry products, in particular hydraulically setting or cement-based materials, such as tile adhesives, joint fillers, putties, sealing slurries and the like. Such Entstaubungsadditive based on hydrocarbons or Kohlenwasserrstoffgemischen cause Langzeitentstaubungswirkung with respect to the treated therewith construction chemical products, which is retained both in closed storage as in open storage, in particular atmospheric oxygen, and this without affecting the processing and performance properties of the way limited to those treated construction chemical products.
