Because of its high cement consumption, which limits its use in concrete construction, self-compacting concrete requires a higher cement content and various admixtures.Therefore, it is prudent to explore alternative options to minimize environmental impacts while creating environmentally friendly self-compacting concrete.This study examines the use of fly ash (FA) and ultrafine slag (UFS) in self-compacting geopolymer concrete (SGC), supplemented with color block iphone case fayalite slag aggregates (FSA).These aggregates, in varying quantities up to 60%, were used instead of traditional sand.

The rheological properties and compressive strength of SGC were investigated.The analysis revealed that the addition of FSA improved the flowability of SGC.Notably, using a combination comprising 60% FSA, the largest slump measurement of 683.5 mm was achieved.

Substituting up to 20% of FSA generally improved the properties of SGC at all ages.After one year, the mixture containing 20% FSA 7gm pravana outperformed other compositions, with a maximum compressive strength of 49.38 MPa.
