Slags as Thermal Energy Storage Media for Concentrated Solar Power and Renewable Energy Integration
ABSTRACT The growing demand for low‐cost, high‐performance thermal energy storage (TES) materials has prompted interest in repurposing metallurgical slags in concentrated solar power (CSP) systems. This review critically evaluates the potential of various steel, copper, and aluminum slags as high‐temperature TES media in packed‐bed configurations ...

Fine ground granulated blast furnace slag for saving quantity of binder [PDF]
Nowadays, it is acknowledged that the use of mineral additives based on ground slag is one of ways of resource saving and improvement of technical properties of cement composites. Mineral additives with fineness similar to the Portland cement fineness are often used to replace part of Portland cement.

Physical Changes and Performance at High Temperatures of Cement‐Slag Blended Concretes
ABSTRACT This study investigates the physical transformations and assesses the performance of blended‐cement concretes exposed to temperatures ranging from ambient to 800°C. Three different grades of cement: 32.5, 42.5, and 52.5, with various contents of ground granulated blast furnace slag (GGBFS), were employed in this research.

CEMENTS AND CONCRETES USING GROUND GRANULATED BLAST-FURNACE SLAG
Abstract. The Russian cement industry is increasing the share of Portland cement production without mineral additives every year, reducing the consumption of granulated blast-furnace slag. This prompted the emergence of a relatively new product – ground granulated blast-furnace slag (GGBS), supplied directly to consumers of Portland cement, who use it ...

Toward Zero Waste Mining: Circular Economy of Copper Slags
Mining and metal extraction processes generate over 90% of global waste. With the rapid increase in population and urbanization, the demand for geotechnical applications and construction materials constantly increases and can absorb the entire quantity of slags generated.

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