Properties of Concrete Modified with Ultra-Fine Slag

Karbala International Journal of Modern Science, 2019
The supplementary cementitious materials (SCM) can be used as a replacement of cement in the construction industry to minimize the drawbacks of normal concrete such as the emission of carbon dioxide so as to be eco-friendly. This paper presents the effect of ultra-fine slag (i.e.

Evaluation of Flexural Behaviour of Steel Slag Fine Aggregates in Concrete [PDF]

E3S Web of Conferences
This paper examines the flexural behavior of reinforced and plain concrete beams with steel slag as a partial substitute for natural fine aggregate. Four concrete mixes were made using 0, 20, 40, and 60 percent replacement of steel slag.
