Compressive Strength and Microstructure Properties of Alkali‐Activated Systems with Blast Furnace Slag, Desulfurization Slag, and Gypsum [PDF]
This study investigates the effect of desulfurization slag (DS) and gypsum (G) on the compressive strength and microstructure properties of blast furnace slag‐(BFS‐) based alkali‐activated systems. DS is produced in a Kambara reactor process of molten iron produced in a steel production process.

ABSTRACT Characteristics of high alkali in Zhundong coal ash may cause ash‐related slag discharge problems at entrained‐flow‐bed (EFB) gasifier. In this study, through exploring melting characteristics and viscosity–temperature characteristics, it is found that MN05, MN14, and MN23 show low FTs (< 1160°C).

The Influence of Corporate Sustainability Rating Methodology on Disclosure Behavior
ABSTRACT The rise of environmental, social, and governance (ESG) investing has illuminated long‐standing concerns over the ability for sustainability rating schemes to accurately convey sustainability‐related performance of firms. This study theorizes and empirically examines how a detailed and transparent rating methodology influences what information
