Abstract
The work aims to reuse two different industrial solid wastes (Dealuminated kaolin (DK) and Electric arc
furnace slag (EAFS)) in the manufacture of eco-friendly binder. The probability of producing the more durable ecofriendly geo-polymer binders is produced from blending EAFS, and DK solid wastes sections with different dosages
of alkaline activator solution. The produced binder was treated at ± 30oC at relative humidity (RH) 98 ± 1 %.
Different experimental tests were performed such as, compressive strength, combined water, and free slag content.
In addition to instrumental techniques such as XRD, DTA/TGA, SEM and FTIR were performed. DK hindered the
formation of micro cracks through EAFS-geopolymer and enhanced the C-S-H formation beside enhanced the
durability of the binder matrixes.
