Effects Of Steel Slag Aggregate Size And Content On ...

Apr 15, 2020· Abstract. This study investigated the self-sensing characteristics of smart ultra-high-performance concretes (UHPCs) containing steel slag aggregates (SSAs) and steel fibers under compression. We used SSAs as functional fillers in smart UHPCs, instead of silica sands, to obtain a uniform filler distribution.

Mechanical Performance Study Of Pervious Concrete Using ...

Jul 20, 2020· The SSA is a by-product of steel production, and it is composed of oxides of calcium, iron, magnesium, aluminum, and other oxides. Steel slag contains a high content of amorphous SiO 2 and CaO, and it can be used as cementitious materials when ground into powder (Tsakiridis et al., 2008; Wang et al., 2013). Further, it has a slightly higher specific gravity and compressive strength than that …
