Mechanical properties of ferrochromium slag in granular layers of flexible pavements

Research on the use of Ferro-Chrome slag in civil engineering applications

“…Both the molten FeCr and the slag flow out into ladles. After gravity separation from the metal, the molten slag, slowly cools in the air, forming a stable and dense crystalline product having an excellent mechanical properties similar to basalt [5,6]. The granulated slag (size less than 4.75mm) samples result from water cooling of the slag whereas lumped slag (size between 8 to 20 mm) samples produced when slag is air-cooled [7].…”

“…Studies [5,6,8,[12][13][14][15] reported that FeCr slag possesses excellent physical properties compared to other aggregate since it has good adhesion and good abrasion, has a rough and porous surface (figure 1) and it lacks clay and organic ingredients in tis composition. However, the water absorption rate is relatively high due to the porous nature of the slag.…”

“…In the last decade, the potential application of FeCr as an alternative aggregate in pavements and road construction has been investigated [2], [3], [5], [7], [12], [14], [21]. In 2001, Lind et al [2] investigated the environmental impact of FeCr slag in road construction.…”

“…Yilmaz and Karaşahin [5] studied the mechanical properties of FeCr slag in granular layers of flexible pavements. The experimental program consisted of two parts: 1) study of the physical and chemical properties of slag, and 2) study of the mechanical properties of specimens made with FeCr slag and limestone as aggregate.…”

Utilization of Steel Slag As Road Base And Subbase Material

“…Yüksek Fırın Cürufu dünyada olduğu gibi Türkiye'de de çimento sanayi, hazır beton gibi pek çok alanda kullanılmaktadır. Ancak entegre tesislerden elde edilen çelikhane cürufu ile ilgili kullanım ve çalışmalar ülkemizde sınırlıdır[40,41]. ABD'de 2003-2009 yılları arasında çelikhane cürufunun kullanıldığı alanlar Çizelge 9 görülmektedir[10].…”
