Applications of Steel Slag Powder and Steel Slag Aggregate ...

The applications of steel slag powder and steel slag aggregate in ultra-high performance concrete (UHPC) were investigated by determining the fluidity, nonevaporable water content, and pore structure of paste and the compressive strength of concrete and by observing the morphologies of hardened paste and the concrete fracture surface. The results show that the fluidity of the paste containing ...

Slag Cement - Lehigh Hanson, Inc.

This rapid cooling, called quenching, creates glassy granules, which are then ground into the fine powder known as slag cement. Slag cement is as old as iron-making itself. In the 1700s, it was combined with lime to make mortar. One of the first major uses of slag-lime cements was construction of the Paris underground in the late 1800s.

Applications of Steel Slag Powder and Steel Slag Aggregate ...

When the cement replacement ratio is 20%, the fluidity of paste containing steel slag powder is approximately 25 mm higher than that of paste without steel slag powder. These results indicate that using steel slag powder as a mineral admixture could improve the fluidity of paste, which is beneficial for the workability of concrete.
