Aggregates – general information. 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

Using such by-products for lightweight aggregate production is a feasible way in recycling of waste materials. Manufacturing artificial lightweight aggregates can be achieved by cold bonding, autoclaving or sintering procedures [1, 2, 5–7, 11, 19].
