Steel Slag as a Substitute for Natural Aggregate in the ...

This article presents the results of an experimental research dealing with the use of steel slag as a partial substitute for natural aggregates in the production of concrete composite. Comparative mixture based on natural aggregates was prepared from the fractions of 0/4, 4/8 and 8/16 mm, which were represented in the volume ratio of 40:30:30.

2018-8-1  One section was built with 100% steel slag, another with aggregates as a mixture of 50% steel slag and 50% diabase, and the third for comparison with 100% diabase aggregates. The test results showed that the skid resistance measured on the top of the surface layer in different sections was similar from 1993 to 1998 ( Motz and Geiseler, 2001 ).

Steel Slag - an overview ScienceDirect Topics

Depending on the used production technology, the steel slag can be divided into a basic oxygen steel slag, an electric arc furnace slag and a ladle furnace slag (De Brito and Saika, 2013). The steel slag is used as a secondary cementitious binder, or aggregates for road construction ( Sheen et al., 2013 ; Manso et al., 2004 ).

The results also indicated the removal of the cross-section (ΣR) of the fast neutrons for the heavy concrete mixes increase by 9% and 10% upon replacing fine sand by the fine aggregates of lead-slag and magnetite, respectively. This is due to the increase in the iron content with addition fine magnetite and lead slag aggregates.

Comprehensive Analysis of Steel Slag as Aggregate for

The BOF slag analysed shows a Los Angeles coefficient of 14, which is lower than limestone value (LA = 25) and other natural aggregates such as basalt (LA = 14.9) and siliceous aggregates (LA = 20). Thus, BOF slag has good toughness and abrasive properties, and it meets the requirements established for the most demanding pavements (T00 and T0).
