Among other stainless steel slags (SSS), argon oxygen decarburisation (AOD)-slag has the potential to be recovered as a binder during the production of new construction materials. Alkali activation and carbonation processes can, in fact, activate the binding properties of the AOD-slag.
Stainless steel is used for buildings for both practical and aesthetic reasons. Stainless steel was in vogue during the art deco period. The most famous example of this is the upper portion of the Chrysler Building (pictured). Some diners and fast-food restaurants use large ornamental panels and stainless fixtures and furniture.

Nevertheless, re-bar steel slag presents a higher concentration of Cr2 O3 compared to the quality steel slag since the former requires strong oxidation to remove the impurities within the scraps. Generally, these slag are characterized by small and dispersed Cr-spinels (max 20 µm), as can be seen in Figure 2.

Introduction. As a ubiquitous by-product of steel production, around 61 million tonnes (Mt) of steel slag is generated yearly worldwide. Over half of this (33 Mt per annum) is produced within the USA and Europe (Proctor et al. 2000; Motz and Geiseler 2001), with an additional 27 Mt from China and Japan (Shen and Forssberg 2003), and 1.2 Mt from Russia (Smirnov et al. 2009).
The current utilization rate of steel slag is only 22% in china, far behind the developed countries. At present, the amount of slag deposited in storage yard adds up to 30Mt, leading to the occupation of farm land and serious pollution to the environment.
