Passivation of Prestressed Steel in Concrete With Slag and Exposed to Chlorides

open access: yesMaterials and Corrosion, EarlyView.
The presence of free sulphides in slag will not adversely affect the long‐term corrosion performance of prestressed concrete structures. The possible adverse effect of free sulphides on early‐stage passivation can subside at later stages as the steel in slag‐based binders has good ability to repassivate.

Reduction, Softening, and Melting Characteristics of Mill Scale‐Based Briquettes for Blast Furnace Ironmaking

open access: yessteel research international, EarlyView.
The study evaluates mill scale‐based briquettes, which meet industrial standards for shatter strength and exhibit a low decrepitation index. Despite their limited reducibility in nonisothermal reduction experiments, softening and melting results indicate potential application as a substitute for conventional acidic iron‐bearing materials for use in ...
