New Geopolymers Based on Electric Arc Furnace Slag

Electric arc furnace slag (EAFS), coming from a steel productive plant in Italy, has been used as new source for geopolymers synthesis. The slag has been geopolymerized alone and with different content of metakaolin (MK) with the aim to investigate if EAFS content plays a role in geopolymerization process. Mechanical properties results and microstructure analysis highlight that the optimum ...
