Abstract:
The use of a mixture of at least one polyol and at least one cyclohexanepolycarboxylic acid derivative for reducing or minimizing the dust emission when handling pulverulent construction chemistry products, processes for the preparation of the pulverulent construction chemistry products and hydraulically setting materials containing the mixture according to the invention are proposed.
