How to improve chemical and physical stability of Waelz slag to withstand long term exposure to weathering and leaching conditions


To investigate the possibilities to use WAELZ slag as a civil engineering material, not harmful to the environment, instead of dumping it.

The project consists of the following main tasks :

- to compare existing standards and specific testing procedures for leachability and mechanical stability;

- to better understand :

* the processes controlling the leaching mechanisms,
* the changes occurring in chemical speciation during long-term exposure to external (weathering factors),
* the physical processes occurring during long-term exposure to weathering and how they govern the alteration of mechanical characteristics.

- to specify operating parameters of WAELZ furnaces which change the mineralogical constitution of slags in order to decrease the leachability and to increase mechanical strength.
