Abstract: ABSTRACT GEOPOLYMER-BASED PERVIOUS CONCRETE PAVEMENT BLOCKS WITH RECYCLED CARBON BLACK A geopolymer-based pervious concrete composition for pavement blocks includes a geopolymer binder (102) produced by alkali activation of fly ash using an alkaline activator solution containing sodium hydroxide and sodium silicate, a coarse aggregate (104) distributed throughout the geopolymer binder (102), and recycled carbon black (106) derived from end- of-life tires as a functional additive incorporated into the geopolymer binder (102). The composition is free of ordinary Portland cement and exhibits an interconnected pore structure configured to permit water infiltration through a pavement surface. The geopolymer binder (102) coats the surfaces of the aggregate particles and bonds the aggregate particles together upon curing. The arrangement of the coarse aggregate (104) within the geopolymer binder (102) creates interstitial voids that form the interconnected pore structure extending through the pavement.
