    摘要： The invention relates to hydrophobing agents for mineral construction materials, the use thereof, methods for the production thereof, mineral construction materials, and constructional parts. The hydrophobing agents according to the invention contain fatty acid salts that comprise a mixture of fatty acid salts of at least two different metal cations or two different ammonium cations or a mixture of at least one metal cation and at least one ammonium cation. The metal cations are selected from the group comprising alkali metals, alkaline earth metals, zinc, aluminum, and rare earths. The content of fatty acid salts of fatty acids that have 8 to 17 C atoms amounts to at least 20 percent by weight relative to the total amount of fatty acid salts in the fatty acid salt mixture.
