More Information
Summary:The invention relates to a method for producing an aggregate for the production of building materials, wherein a starting material containing at least one fibre-containing waste fraction has had heavy materials removed and been comminuted in order to obtain a substantially free-flowing aggregate. Improved product properties can be achieved in such a way that the fibre content is set between 3% and 45%, preferably between 5% and 25%, and more preferably between 7% and 12%, and a mass fraction of between 2% and 25%, preferably between 2% and 10%, and more preferably between 3% and 8%, of a fine-grain inorganic additive is set. The invention further relates to an aggregate produced according to this method, and to asphalt or concrete.
