Abstract
The invention relates to a mixture of a calcium sulfate-based mineral binder and at least one additive that imparts hydrophobic properties to the calcium sulfate-based mineral binder. Said additive is a salt, a hydrophilic fatty acid, or a binder mixture containing fatty acid salts. 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, or the content of fatty acids that have 8 to 14 C atoms amounts to at least 10 percent by weight relative to the total amount of fatty acid salts in the fatty acid salt mixture, or both. The construction materials according to the invention can be gypsum boards, gypsum blocks, or other molded parts, especially gypsum plasterboards.
