Investigation of mechanical and microstructural performance of alkali activated electrical arc furnace slag mortars
Abstract
The production of Portland cement, resulting in the release
of CO2 gas, excessive energy and natural resource consumption, has
led to search for alternative materials with similar physical and mechanical properties
to the Portland cement of the scientific community. Geopolymers as alternative
to conventional cement have a great potential for use in terms of their
mechanical and durability properties. For this reason, it is necessary to
investigate the usability of a new material alternative to cement, to reduce
the environmental impact and for the disposal of Electric Arc Furnace Slag
(EAFS), which is produced in large quantities in the primary target world and
in Turkey and which causes storage space bottleneck. For this purpose, the
mechanical and microstructure of the activated EAFS exposed to different curing
conditions at three different sodium concentrations with a silicate module was
investigated. When the results are examined, it is obvious that the strength
increases with the increase of the sodium concentration. In addition, the
literature on which alkali activation of EAFS has been added for the first
time.
