Effect of blast-furnace slag on physicochemical properties of pozzolan-based geopolymers
, 2021This research focuses on the synthesis and characterization of geopolymers based on French pozzolan (P) by adding two types of blast-furnace slags with different chemical compositions (L1 and L2). The slags amount varied between 0% and 50%.

This chapter is dedicated to several kinds of natural pozzolans that occur around the globe and describes their specific characteristics, origin and use in concrete. Moreover, the advantages and disadvantages of their use in concrete mixes are highlighted in terms of concrete properties. In particular, the referenced properties in this chapter are that
