slag applications in aggregate crushing

Aggregates - general information - Euroslag

2021-7-20  The use of slag aggregates from iron and steel production in construction dates back to the Romans who used crushed slag from the crude iron production of that time to build their roads. Nowadays, slag is still used to build roads. However, slag use is not limited to roads anymore, but slag aggregates are widely used in all kinds of civil works.
