A Review of Current Research on the Use of Geopolymer Recycled Aggregate Concrete for Structural Members.

A noticeable increase in the ultimate deflection, i.e., the deflection of the post-peak softening branch at which the specimen attains 85% of its load capacity, was only found when ten vertical reinforcing bars were put in place (21% and 25% for pitch reduction from 250 mm up to 150 mm and 50 mm, respectively), while a clear trend was not revealed for six and eight longitudinal rebars [ 51 ].
