Abstract
In an effort to reduce the environmental damage that comes from the open disposal of non-biodegradable waste rubber, the use of scrap tires as building materials has been encouraged. By using tyre grinds instead of natural aggregates, geopolymer concrete (GPC) would have a higher sustainability value. This work was intended to ascertain the amount of potential adverse effects of employing crumb rubber (CR) in GPC, despite the paucity of literature addressing the harm done to GPC properties by rubber aggregates. Furthermore, by adding additives like cement and fibers, this research seeks to alleviate any associated loss in strength and durability. Geopolymer specimens with CR replacement of fine aggregates by volume (0, 5, 10 and 15%) showed a compressive strength reduction of up to 17% when tested according to ASTM standards. Substituting the total binder by weight with Ordinary Portland cement (OPC) (0%, 5%, 10%, 15%, and 20%) improved the microstructural integrity of the rubberised geopolymer mix with the highest percentage of OPC.
