International Conference on
Stainless steel slag waste as a replacement for cement in mortars
Francisco Agrela, Julia Rosales
and

University of Cordoba, Spain
H
uge quantities of stainless Steel Slags are produced
in several European Production Plants of this type of
steel. Normally, these waste are moved to dumpfields, and
minimum percentages are recycled. In the University of
Cordoba the group of Construction Engineering have studied
during last three years the feasibility of replacing cement
by stainless steel slag waste and improving the mechanical
properties of the slag waste by using different types of
treatments.
The application of stainless steel slag waste could reduce the
use of raw materials for manufacturing cement and provides
a profit from the large amount of waste generated.
In these studies, we analyzed the cementation and pozzolanic
reaction characteristics of stainless steel slag waste to
evaluate its strength activity index and its environmental
impact. The cement was replaced with different substitution
percentages of untreated stainless steel slag waste and slag
waste that was processed through crushing, burning and
both treatment to determine the optimum replacement
ratio according to its mechanical properties.
We determined that replacing cement with stainless steel
slag waste for the manufacture of mortar could improve the
mechanical properties up to a certain degree of substitution.
This use can provide some value to the large amount of waste
produced and reduce the consumption of raw materials.
