Cover surface for sports grounds

摘要

The subject matter of the present invention is a cover surface for sports grounds. The claimed cover surface for tennis courts or sports pitches is made using a ternary mixture based on blast-furnace slag gravel and sand, preground binder, ash and water. It is quite particularly intended for covering tennis courts of the type known by the name "clay", but may also be applied to municipal sports grounds such as for volleyball, for example.
