Use Of Compounds Containing Aluminium Oxide And Silicon Oxide For Producing A Hydrophilic Building Product

Abstract

The use of a binder system comprising compounds containing aluminium oxide and silicon oxide for producing a hydrophilic building product, characterized in that the sum of the oxides calculated as Al2O3 and SiO2 in the binder system is ≧40% by weight, based on the water-free binder system, and the contact angle of an oil drop placed on the surface of the cured building product is ≧90°, where the contact angle determination is carried out under water, is proposed. The said hydrophilicity makes the building product easy to clean, with simple rinsing with water often being sufficient.
